- * Some notes about how inet (currently only tcp) works on OSE.
- * The driver uses OSE signals to communicate with the one_inet
- * process. Because of the difference in how signals and file descriptors
- * work the whole select/deselect mechanic is very different.
- * In ose when a sock_select is done a function is called. That function
- * notes the changes that the driver want to do, but does not act on it.
- * later when the function returns the new desired state is compared
- * to the previous state and the apprioriate actions are taken. The action
- * is usually to either request more data from the stack or stop requesting
- * data.
- *
- * One thing to note is that the driver never does select/deselect. It always
- * listens for the signals. Flow of data is regulated by sending or not sending
- * signals to the ose inet process.
- *
- * The interesting functions to look at are:
- * * inet_driver_select : called when sock_select is called
- * * tcp_inet_ose_dispatch_signal : checks state changes and sends new signals
- * * tcp_inet_drv_output_ose : ready output callback, reads signals and calls
- * dispatch_signal
- * * tcp_inet_drv_input_ose : ready input callback.

- Erlang/OTP has been ported to the realtime operating
- system OSE. The port supports both smp and non-smp
- emulator. For details around the port and how to started
- see the User's Guide in the <seealso
- marker="ose:ose_intro">ose</seealso> application. </p>
- <p>
- Note that not all parts of Erlang/OTP has been ported. </p>
- <p>
- Notable things that work are: non-smp and smp emulators,
- OSE signal interaction, crypto, asn1, run_erl/to_erl,
- tcp, epmd, distribution and most if not all non-os
- specific functionality of Erlang.</p>
- <p>
- Notable things that does not work are: udp/sctp, os_mon,
- erl_interface, binding of schedulers.</p>

- <description>
- <p>Writing Linked-in drivers that also work on Enea OSE is very similar for
- how you would do it for Unix. The difference from Unix is that
- driver_select, ready_input and ready_output all work with signals
- instead of file descriptors. This means that the driver_select is
- used to specify which type of signal should trigger calls to
- ready_input/ready_output. The functions described below are available
- to driver programmers on Enea OSE to facilitate this.

- <title>Starting Erlang/OTP</title>
- <p>
- Starting Erlang/OTP on OSE is not as simple as on Unix/Windows (yet).
- First of all you have to explicitly use the beam (or beam.smp) executables
- found in erts-X.Y.Z/bin as the load module that you run. This in turn
- means that you have to supply the raw beam arguments to the emulator
- when starting. Fortunately <c>erl</c> on Unix/Windows has a
- undocumented flag called <c>-emu_args_exit</c> that can be used to
- figure out what the arguments to beam look like. For example:</p>
- <code># erl +Mut false +A 10 +S 4:4 +Muycs256 +P 2096 +Q 2096 -emu_args_exit
--Mut
-false
--A
-10
--S
-4:4
--Muycs256
--P
-2096
--Q
-2096
---
--root
-/usr/local/lib/erlang
--progname
-erl
---
--home
-/home/erlang
---</code>
- <p>
- The arguments are printed on separate lines to make it possible to know
- what has to be quoted with &quot;. Each line is one quotable unit.
- So taking the arguments above you can supply them to pm_create or
- just execute directly on the command line. For example:</p>
- <code>rtose@acp3400> pm_install erlang /mst/erlang/erts-6.0/bin/beam.smp
-rtose@acp3400> pm_create -c ARGV="-Mut false -A 10 -S 4:4 -Muycs256 -P 2096 -Q 2099 -- -root /mst/erlang -progname erl -- -home /mst/erlang --" erlang
-pid: 0x110059
-rtose@acp3400> pm_start 0x110059</code>
- <p>
- Also note that since we are running erl to figure out the arguments on a
- separate machine the paths have to be updated. In the example above
- <c>/usr/local/lib/erlang</c> was replaced by <c>/mst/erlang/</c>. The
- goal is to in future releases not have to do the special argument handling
- but for now (OTP 17.0) you have to do it.
- </p>
- <note>
- Because of a limitation in the way the OSE handles stdio when starting
- load modules using pm_install/create the Erlang shell only reads every
- other command from stdin. However if you start Erlang using run_erl
- you do not have this problem. So it is highly recommended that you
- start Erlang using run_erl.
- </note>
- </section>
-
- <section>
- <title>run_erl and to_erl</title>
- <p>
- In OSE run_erl and to_erl are combined into a single load module called
- run_erl_lm. Installing and starting the load module will add two new
- shell commands called run_erl and to_erl. They work in exactly the same
- way as the unix variants of run_erl and to_erl, except that the read
- and write pipes have to be placed under the /pipe vm. One additional
- option also exists to run_erl on ose:
- <taglist>
- <tag><c>-block Name</c></tag>
- <item>The name of the install handle and block that will be created/used by
- installing and exectuting the first part of the command. If nothing
- if given the basename of the load module will be used for this value.
- Example:
- <code>pm_install erlang /path/to/erlang/vm/beam.smp
-run_erl -daemon -block erlang /pipe/ /mst/erlang_logs/ "beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"</code>
- </item>
- </taglist>
- The same argument munching as when starting Erlang/OTP without run_erl
- has to be done. If <c>-daemon</c> is given then all error printouts
- are sent to the ramlog.
- See also
- <seealso marker="erts:run_erl">run_erl</seealso> for more details.
- </p>
- <p>
- Below is an example of how to get started with <c>run_erl_lm</c>.
- <code>rtose@acp3400> pm_install run_erl_lm /mst/erlang/erts-6.0/bin/run_erl_lm
-rtose@acp3400> pm_create run_erl_lm
-pid: 0x1c005d
-rtose@acp3400> pm_start 0x1c005d
-rtose@acp3400> mkdir /mst/erlang_log
-rtose@acp3400> run_erl -daemon /pipe/ /mst/erlang_log/ "/mst/erlang/erts-6.0/bin/beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"
-rtose@acp3400> to_erl
-Attaching to /pipe/erlang.pipe.1 (^C to exit)
-os:type().
-{ose,release}
-2>
-'to_erl' terminated.</code>
- Note that Ctrl-C is used instead of Ctrl-D to exit the to_erl shell.

- <title>Introduction</title>
- <p>The main way which programs on Enea OSE interact is through the
- usage of message passing, much the same way as Erlang processes
- communicate. There are two ways in which an Erlang programmer can
- interact with the signals sent from other Enea OSE processes; either
- through the provided <c>ose</c> module, or by writing a custom linked-in
- driver. This User's Guide describes and provides examples for both
- approaches.

- <title>Signals in Erlang</title>
- <p>Erlang/OTP on OSE provides a erlang module called
- <seealso marker="ose:ose">ose</seealso> that can be used to interact
- with other OSE processes using message passing. The api in the module
- is very similar to the native OSE api, so for details of how the
- functions work please refer to the official OSE documenation. Below
- is an example usage of the API.
- </p>
- <code>1> P1 = ose:open("p1").
-#Port&gt;0.344>
-2> ose:hunt(P1,"p2").
-{#Port&gt;0.344>,1}
-3> P2 = ose:open("p2").
-#Port&gt;0.355>
-4> flush().
-Shell got {mailbox_up,#Port&gt;0.344>,{#Port&gt;0.344>,1},852189}
-ok
-5> ose:listen(P1,[1234]).
-ok
-6> ose:send(P2,ose:get_id(P1),1234,&gt;&gt;"hello">>).
-ok
-7> flush().
-Shell got {message,#Port&gt;0.344>,{852189,1245316,1234,&gt;&gt;"hello">>}}

- <title>Signals in a Linked-in driver</title>
- <p>
- Writing Linked-in drivers for OSE is very similar to how it is done
- for Unix/Windows. It is only the way in which the driver subscribes
- and consumed external events that is different. In Unix (and Windows)
- file descriptiors (and Event Objects) are used to select on. On OSE
- we use signals to deliver the same functionality. There are two large
- differences between a signal and an fd.
- </p>
- <p>
- In OSE it is not possible for a signal number to be a unique identifier
- for a resource in the same way as an fd is. For example; let's say we
- implement a driver that does an asynchronous hunt that uses signal
- number 1234 as the hunt_sig. If we want to be able to have multiple
- hunt ports running at the same time we have to have someway of routing
- the signal to the correct port. This is achieved by supplying a secondary
- id that can be retrieved through the meta-data or payload of the signal,
- e.g:
- <code>ErlDrvEvent event = erl_drv_ose_event_alloc(1234,port,resolver);</code>
- The event you get back from
- <seealso marker="ose_erl_driver#erl_drv_ose_event_alloc">
- erl_drv_ose_event_alloc</seealso> can then be used by
- <seealso marker="erts:erl_driver#driver_select">driver_select</seealso>
- to subscribe to signals. The first argument is just the signal number
- that we are interested in. The second is the id that we choose to use,
- in this case the port id that we got in the
- <seealso marker="erts:driver_entry#start">start</seealso> callback is
- used. The third argument is a function pointer to a function that can
- be used to figure out the id from a given signal. The fourth argument can
- point to any additional data you might want to associate with the event.
- There is a complete. You can examine the data contained in the event with
- <seealso marker="ose_erl_driver#erl_drv_ose_event_fetch">erl_drv_ose_event_fetch</seealso>
- , eg:
- <code>erl_drv_ose_event_fetch(event, &amp;signal, &amp;port, (void **)&amp;extra);</code>
- example of what this could look like in
- <seealso marker="#example">the next section</seealso>.
- <note>It is very important to issue the driver_select call before
- any of the signals you are interested in are sent. If driver_select
- is called after the signal is sent, there is a high probability that it
- will be lost.</note>
- </p>
- <p>
- The other difference from unix is that in OSE the payload of the event
- (i.e. the signal data) is already received when the ready_output/input
- callbacks are called. This means that you access the data of a signal
- by calling <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
- erl_drv_ose_get_signal</seealso>. Additionally multiple signals might be
- associated with the event, so you should call
- <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
- erl_drv_ose_get_signal</seealso> until <c>NULL</c> is returned.

-
- <section>
- <title>Introduction</title>
- <p>To ease the use of Cover there is a web based user interface
- to Cover called WebCover. WebCover is designed to be started
- and used via WebTool. It is possible to Cover compile Erlang
- modules and to generate printable Cover and Call analyses via
- the web based user interface.</p>
- </section>
-
- <section>
- <title>Start the Web Based User Interface to Cover</title>
- <p>To start WebCover you can either start WebTool, point a
- browser to the start page of WebTool and start WebCover from
- there, or you can use the <c>start_webtool</c> script to start
- Webtool, WebCover and a browser. See WebTool documentation for
- further information.</p>
- <p>Currently WebCover is only compatible
- with Internet Explorer and Netscape Navigator 4.0 and higher.</p>
- </section>
-
- <section>
- <title>Navigating WebCover</title>
- <p>From the menu in the lefthand frame you can select the
- <c>Nodes</c>, <c>Compile</c>, <c>Import</c> or <c>Result</c>
- page.</p>
- <p>From the <c>Nodes</c> page you can add remote nodes to
- participate in the coverage analysis. Coverage data from all
- involved nodes will then be merged during analysis.</p>
- <p>From the <c>Compile</c> page you can Cover compile <c>.erl</c>
- or <c>.beam</c> files.</p>
- <p>From the <c>Import</c> page you can import coverage data from
- a previous analysis. Imported data will then be merged with
- the current coverage data. <em>Note</em> that it is only possible to
- import files with the extension <c>.coverdata</c>.</p>
- <p>From the <c>Result</c> page you can analyse, reset or export
- coverage data.</p>
- <p>Please follow the instructions on each page.</p>

- <title>Introduction </title>
- <p>WebTool provides an easy and efficient way to implement web
- based tools with Erlang/OTP. WebTool configures and starts the
- webserver and the various web based tools.</p>
- <p>All tools that shall run under WebTool must have a *.tool
- file in the code path or in its priv directory. When WebTool
- starts it searches the code path for such files. For each
- <c>ebin</c> directory in the path, the <c>priv</c> directory is
- also searched. The *.tool files contain the configuration data
- for each web based tool.</p>
- </section>
-
- <section>
- <title>Starting WebTool</title>
- <p>Start WebTool by calling the function <c>webtool:start/0</c> or
- <c>webtool:start/2</c>. If <c>webtool:start/0</c> is used the
- start page of WebTool is available at
- <em>http://localhost:8888/</em> or
- <em>http://127.0.0.1:8888/</em>, and the directory containing
- the root directory for the webserver, is assumed to be
- <c><![CDATA[webtool-<vsn>/priv]]></c>.</p>
- <p>Use <c>webtool:start/2</c> if the default path for the root
- directory, port, ip-number or server name can not be used. See
- the Reference Manual for <seealso marker="webtool">webtool</seealso> for more information.</p>
- <p>WebTool, with the default configuration as in <c>start/0</c>,
- can also be started with the <c>start_webtool</c> script which
- is available in the <c>priv</c> directory of the WebTool
- application. See the Reference Manual for <seealso marker="start_webtool">start_webtool</seealso> for further
- information about this script. For Windows users, the batch file
- <c>start_webtool.bat</c> can be used for the same purpose.</p>
- </section>
-
- <section>
- <title>Using WebTool</title>
- <p>Start WebTool and point the browser to the corresponding URL.
- At the top of the page there is a frame with a link named
- <em>WebTool</em>. Click that link and a page where it is
- possible to start the available tools will appear in the main
- frame.</p>
- </section>
-
- <section>
- <title>Start a web based tool</title>
- <p>Click on the link labeled <em>WebTool</em> in the topmost frame,
- select the checkbox for each tool to start and
- click on the button labeled <em>Start</em>. A link to each tool
- that WebTool succeeded to start will appear in the topmost frame.</p>
- </section>
-
- <section>
- <title>Stop a web based tool</title>
- <p>Click on the link labeled <em>WebTool</em> in the topmost
- frame. Select <em>Stop Tools</em> in the left frame. Select the
- checkbox for each tool to stop and click on the button labeled
- <em>Stop</em>.</p>
- </section>
-
- <section>
- <title>Develop new web based tools</title>
- <p>WebTool can be used as a framework when developing new web based
- tools.</p>
- <p>A web based tool running under WebTool will typically consist of
- three parts.</p>
- <list type="bulleted">
- <item>A *.tool file which defines how WebTool can find the tool's
- configuration data</item>
- <item>The Erlang code generating the web interface to the tool (HTML
- code)</item>
- <item>The tool itself.</item>
- </list>
- <p>In most cases it is a good idea to separate the code for
- creation of the html-pages and the code for the logic. This
- increases the readability of the code and the logic might be
- possible to reuse.</p>
-
- <section>
- <title>The *.tool file</title>
- <p>When WebTool starts it searches the current path for
- <c>*.tool</c> files to find all available tools. The *.tool
- file contains a version identifier and a list of tuples which
- is the configuration data. The version identifier specifies
- the *.tool file version, i.e. not the version of
- webtool. Currently the only valid version is "1.2" and the
- only valid configuration tag is
- <c>config_func</c>. <c>config_func</c> specifies which
- function WebTool must call to get further configuration data
- for the tool. This means that a *.tool file generally must
- look like this:</p>
- <code type="none">
- {version,"1.2"}.
- [{config_func,{Module,Function,Arguments}}]. </code>
- <p><c>Module</c> is the name of the module where the callback
- function is defined. <c>Function</c> is the name of the
- callback function, and <c>Arguments</c> is the list of
- arguments to the callback function.</p>
- </section>
-
- <section>
- <title>The configuration function</title>
- <p>The *.tool file points out a configuration function. This
- function must return a list of configuration parameters (see
- the Reference Manual for <seealso marker="webtool">webtool</seealso>).</p>
- <p>The <c>web_data</c> parameter is mandatory and it specifies
- the name of the tool and the link to the tool's start
- page. All other parameters are optional.</p>
- <p>If the tool requires any processes to run, the <c>start</c>
- parameter specifies the function that WebTool must call in
- order to start the process(es).</p>
- <p>The <c>alias</c> parameters are passed directly on to the
- webserver (INETS). The webserver has three ways to create
- dynamic web pages CGI, Eval Scheme and Erl Scheme. All tools
- running under WebTool must use Erl Scheme.</p>
- <p>Erl Scheme tries to resemble plain CGI. The big difference is
- that Erl Scheme can only execute Erlang code. The code will
- furthermore be executed on the same instance as the webserver.</p>
- <p>An URL which calls an Erlang function with Erl Scheme can have
- the following syntax:</p>
- <code type="none"><![CDATA[
-http://Servername:Port/ErlScriptAlias/Mod/Func<?QueryString> ]]></code>
- <p>An <c>alias</c> parameter in the configuration function can be
- an ErlScriptAlias as used in the above URL. The definition of
- an ErlScriptAlias shall be like this:</p>
- <p><c>{alias,{erl_alias,Path,[Modules]}}</c>, e.g.</p>
- <p><c>{alias,{erl_alias,"/testtool",[helloworld]}}</c></p>
- <p>The following URL will then cause a call to the function
- helloworld:helloworld/2 (if WebTool is started with default
- settings i.e. servername "localhost" and port 8888):</p>
- <p><c>http://localhost:8888/testtool/helloworld/helloworld</c></p>
- <p>Note that the module <c>helloworld</c> must be in the code
- path of the node running WebTool.</p>
- <p>Functions that are called via the Erl Scheme must take two
- arguments, <c>Environment</c> and <c>Input</c>.
- </p>
- <list type="bulleted">
- <item><c>Environment</c> is a list of key/value tuples.</item>
- <item><c>Input</c> is the part of the URL after the "?", i.e. the
- part of the URL containing name-value pairs. If the page was
- called with the URL:
- <br></br>
-<c><![CDATA[http://localhost:8888/testtool/helloworld/helloworld?input1=one&amp;input2=two]]></c> <br></br>
-<c>Input</c> will be the string
- <c><![CDATA["input1=one&amp;input2=two"]]></c>. In the module
- <c>httpd</c> in the INETS application there is a function
- <c>parse_query</c> which will parse such a string and return
- a list of key-value tuples.</item>
- </list>
- <p>An <c>alias</c> parameter in the configuration function can
- also be a normal path alias. This can e.g. be used to point
- out a directory where HTML files are stored. The following
- definition states that the URL
- <c>http://localhost:8888/mytool_home/</c> really points to the
- directory <c>/usr/local/otp/lib/myapp-1.0/priv</c>:</p>
- <p><c>{alias,{"/mytool_home","/usr/local/otp/lib/myapp-1.0/priv"}}</c></p>
- <p>See the INETS documentation, especially the module
- <c>mod_esi</c>, for a more in depth coverage of the Erl Scheme.</p>
- </section>
-
- <section>
- <title>A small example</title>
- <p>A Hello World example that uses Erl Scheme would look like
- this. Note that this example does not have a process running
- and thus does not need a <c>start</c> parameter in the
- configuration function.
- </p>
- <p><em>helloworld.erl:</em></p>
- <pre>
- -module(helloworld).
- -export([config_data/0]).
- -export([helloworld/2]).
-
- config_data()->
- {testtool,
- [{web_data,{"TestTool","/testtool/helloworld/helloworld"}},
- {alias,{erl_alias,"/testtool",[helloworld]}}]}.
-
- helloworld(_Env,_Input)-&gt;
- [header(),html_header(),helloworld_body(),html_end()].
-
- header() -&gt;
- header("text/html").
-
- header(MimeType) -&gt;
- "Content-type: " ++ MimeType ++ "\r\n\r\n".
-
- html_header() -&gt;
- "&lt;HTML&gt;
- &lt;HEAD&gt;
- &lt;TITLE&gt;Hello world Example &lt;/TITLE&gt;
- &lt;/HEAD&gt;\n".
-
- helloworld_body()-&gt;
- "&lt;BODY&gt;Hello World&lt;/BODY&gt;".
-
- html_end()-&gt;
- "&lt;/HTML&gt;".
- </pre>
- <p>To use this example with WebTool a *.tool file must be created
- and added to a directory in the current path, e.g. the same
- directory as the compiled <c>helloworld.beam</c>.</p>
- <p><em>testtool.tool:</em></p>
- <code type="none">
- {version,"1.2"}.
- [{config_func, {helloworld,config_data,[]}}].
- </code>
- <p>When <c>helloworld.erl</c> is compiled, start WebTool by
- calling the function <c>webtool:start()</c> and point your
- browser to <em>http://localhost:8888/</em>. Select WebTool in
- the topmost frame and start TestTool from the web page. Click
- on the link labeled <em>TestTool</em> in the topmost frame.</p>

-## -- Optional Feature, and Bug Tests ------------------------------------------
-
-## These tests cannot (always) be done automatically when cross compiling. You

-
-## Note that some of these values will override results of tests performed
-## by `configure', and some will not be used until `configure' is sure that
-## it cannot figure the result out.
-
-## The `configure' script will issue a warning when a default value is used.
-## When a variable has been set, no warning will be issued.
-
-# * `erl_xcomp_after_morecore_hook' - `yes|no'. Defaults to `no'. If `yes',
-# the target system must have a working `__after_morecore_hook' that can be
-# used for tracking used `malloc()' implementations core memory usage.
-# This is currently only used by unsupported features.
-#erl_xcomp_after_morecore_hook=
-
-# * `erl_xcomp_bigendian' - `yes|no'. No default. If `yes', the target system
-# must be big endian. If `no', little endian. This can often be
-# automatically detected, but not always. If not automatically detected,
-# `configure' will fail unless this variable is set. Since no default
-# value is used, `configure' will try to figure this out automatically.
-#erl_xcomp_bigendian=
-
-# * `erl_xcomp_double_middle` - `yes|no`. No default. If `yes`, the
-# target system must have doubles in "middle-endian" format. If
-# `no`, it has "regular" endianness. This can often be automatically
-# detected, but not always. If not automatically detected,
-# `configure` will fail unless this variable is set. Since no
-# default value is used, `configure` will try to figure this out
-# automatically.
-#erl_xcomp_double_middle_endian
-
-# * `erl_xcomp_clock_gettime_cpu_time' - `yes|no'. Defaults to `no'. If `yes',
-# the target system must have a working `clock_gettime()' implementation
-# that can be used for retrieving process CPU time.
-#erl_xcomp_clock_gettime_cpu_time=
-
-# * `erl_xcomp_getaddrinfo' - `yes|no'. Defaults to `no'. If `yes', the target
-# system must have a working `getaddrinfo()' implementation that can
-# handle both IPv4 and IPv6.
-#erl_xcomp_getaddrinfo=
-
-# * `erl_xcomp_gethrvtime_procfs_ioctl' - `yes|no'. Defaults to `no'. If `yes',
-# the target system must have a working `gethrvtime()' implementation and
-# is used with procfs `ioctl()'.
-#erl_xcomp_gethrvtime_procfs_ioctl=
-
-# * `erl_xcomp_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the
-# target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
-# that can be used on `brk' and `sbrk' symbols used by the `malloc()'
-# implementation in use, and by this track the `malloc()' implementations
-# core memory usage. This is currently only used by unsupported features.
-#erl_xcomp_dlsym_brk_wrappers=
-
-# * `erl_xcomp_kqueue' - `yes|no'. Defaults to `no'. If `yes', the target
-# system must have a working `kqueue()' implementation that returns a file
-# descriptor which can be used by `poll()' and/or `select()'. If `no' and
-# the target system has not got `epoll()' or `/dev/poll', the kernel-poll
-# feature will be disabled.
-#erl_xcomp_kqueue=
-
-# * `erl_xcomp_linux_clock_gettime_correction' - `yes|no'. Defaults to `yes' on
-# Linux; otherwise, `no'. If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on
-# the target system must work. This variable is recommended to be set to
-# `no' on Linux systems with kernel versions less than 2.6.
-#erl_xcomp_linux_clock_gettime_correction=
-
-# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,
-# `no'. If `yes', the target system must have NPTL (Native POSIX Thread
-# Library). Older Linux systems have LinuxThreads instead of NPTL (Linux
-# kernel versions typically less than 2.6).
-#erl_xcomp_linux_nptl=
-
-# * `erl_xcomp_linux_usable_sigaltstack' - `yes|no'. Defaults to `yes' on Linux;
-# otherwise, `no'. If `yes', `sigaltstack()' must be usable on the target
-# system. `sigaltstack()' on Linux kernel versions less than 2.4 are
-# broken.
-#erl_xcomp_linux_usable_sigaltstack=
-
-# * `erl_xcomp_linux_usable_sigusrx' - `yes|no'. Defaults to `yes'. If `yes',
-# the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS. Old
-# LinuxThreads thread libraries (Linux kernel versions typically less than
-# 2.2) used these signals and made them unusable by the ERTS.
-#erl_xcomp_linux_usable_sigusrx=
-
-# * `erl_xcomp_poll' - `yes|no'. Defaults to `no' on Darwin/MacOSX; otherwise,

-
-## *NOTE*! These variables currently have *no* effect if you configure using

-
-# * `erl_xcomp_build' - The build system used. This value will be passed as
-# `--build=$erl_xcomp_build' argument to the `configure' script. It does
-# not have to be a full `CPU-VENDOR-OS' triplet, but can be. The full
-# `CPU-VENDOR-OS' triplet will be created by

-## -- Optional Feature, and Bug Tests ------------------------------------------
-
-## These tests cannot (always) be done automatically when cross compiling. You
-## usually do not need to set these variables. Only set these if you really
-## know what you are doing.
-
-## Note that some of these values will override results of tests performed
-## by `configure', and some will not be used until `configure' is sure that
-## it cannot figure the result out.
-
-## The `configure' script will issue a warning when a default value is used.
-## When a variable has been set, no warning will be issued.
-
-# * `erl_xcomp_after_morecore_hook' - `yes|no'. Defaults to `no'. If `yes',
-# the target system must have a working `__after_morecore_hook' that can be
-# used for tracking used `malloc()' implementations core memory usage.
-# This is currently only used by unsupported features.
-#erl_xcomp_after_morecore_hook=
-
-# * `erl_xcomp_bigendian' - `yes|no'. No default. If `yes', the target system
-# must be big endian. If `no', little endian. This can often be
-# automatically detected, but not always. If not automatically detected,
-# `configure' will fail unless this variable is set. Since no default
-# value is used, `configure' will try to figure this out automatically.
-#erl_xcomp_bigendian=
-
-# * `erl_xcomp_double_middle` - `yes|no`. No default. If `yes`, the
-# target system must have doubles in "middle-endian" format. If
-# `no`, it has "regular" endianness. This can often be automatically
-# detected, but not always. If not automatically detected,
-# `configure` will fail unless this variable is set. Since no
-# default value is used, `configure` will try to figure this out
-# automatically.
-#erl_xcomp_double_middle_endian
-
-# * `erl_xcomp_clock_gettime_cpu_time' - `yes|no'. Defaults to `no'. If `yes',
-# the target system must have a working `clock_gettime()' implementation
-# that can be used for retrieving process CPU time.
-#erl_xcomp_clock_gettime_cpu_time=
-
-# * `erl_xcomp_getaddrinfo' - `yes|no'. Defaults to `no'. If `yes', the target
-# system must have a working `getaddrinfo()' implementation that can
-# handle both IPv4 and IPv6.
-#erl_xcomp_getaddrinfo=
-
-# * `erl_xcomp_gethrvtime_procfs_ioctl' - `yes|no'. Defaults to `no'. If `yes',

-# is used with procfs `ioctl()'.
-#erl_xcomp_gethrvtime_procfs_ioctl=
-
-# * `erl_xcomp_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the
-# target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
-# that can be used on `brk' and `sbrk' symbols used by the `malloc()'
-# implementation in use, and by this track the `malloc()' implementations
-# core memory usage. This is currently only used by unsupported features.
-#erl_xcomp_dlsym_brk_wrappers=
-
-# * `erl_xcomp_kqueue' - `yes|no'. Defaults to `no'. If `yes', the target
-# system must have a working `kqueue()' implementation that returns a file
-# descriptor which can be used by `poll()' and/or `select()'. If `no' and
-# the target system has not got `epoll()' or `/dev/poll', the kernel-poll
-# feature will be disabled.
-#erl_xcomp_kqueue=
-
-# * `erl_xcomp_linux_clock_gettime_correction' - `yes|no'. Defaults to `yes' on
-# Linux; otherwise, `no'. If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on
-# the target system must work. This variable is recommended to be set to
-# `no' on Linux systems with kernel versions less than 2.6.
-#erl_xcomp_linux_clock_gettime_correction=
-
-# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,
-# `no'. If `yes', the target system must have NPTL (Native POSIX Thread
-# Library). Older Linux systems have LinuxThreads instead of NPTL (Linux
-# kernel versions typically less than 2.6).
-#erl_xcomp_linux_nptl=
-
-# * `erl_xcomp_linux_usable_sigaltstack' - `yes|no'. Defaults to `yes' on Linux;
-# otherwise, `no'. If `yes', `sigaltstack()' must be usable on the target
-# system. `sigaltstack()' on Linux kernel versions less than 2.4 are
-# broken.
-#erl_xcomp_linux_usable_sigaltstack=
-
-# * `erl_xcomp_linux_usable_sigusrx' - `yes|no'. Defaults to `yes'. If `yes',
-# the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS. Old
-# LinuxThreads thread libraries (Linux kernel versions typically less than
-# 2.2) used these signals and made them unusable by the ERTS.
-#erl_xcomp_linux_usable_sigusrx=
-
-# * `erl_xcomp_poll' - `yes|no'. Defaults to `no' on Darwin/MacOSX; otherwise,
