See +the License for the specific language governing rights and limitations +under the License. + +%CopyrightEnd% + +=============================================================================== + +This document describes how to cross compile Erlang/OTP. Note that the support +for cross compiling Erlang/OTP is in its early stage of development, and +should be considered as experimental. You are encouraged to read the whole +document before attempting to cross compile Erlang/OTP. + +Building Erlang/OTP can be done either by using the `$ERL_TOP/otp_build' +script, or by invoking `configure' and `make' directly. The +`erl-xcomp.conf.template' file contains all available configuration variables +and can be used as a template when creating a configuration. See +`erl-xcomp-TileraMDE2.0-tilepro.conf` and `erl-xcomp-x86_64-saf-linux-gnu.conf' +for examples of working configurations. + +The configuration files can be passed to `$ERL_TOP/otp_build configure' using +the `--xcomp-conf' command line argument. Note that `configure' doesn't accept +this command line argument. When using the `configure' script directly, pass +the configuration variables as arguments to `configure' (or exported in the +environment). If the default behavior of a variable is satisfactory, the +variable doesn't need to be set. However, the `configure' script will issue a +warning when a default value is used. When a variable has been set, no warning +will be issued. + +All Erlang/OTP applications except the `wx' application can be cross compiled. +The build of the `wx' driver will currently be automatically disabled when +cross compiling. + +Note, that `$ERL_TOP/otp_build configure' will produce a default configuration +that differs from what `$ERL_TOP/configure' will produce by default. For +example, currently `--disable-dynamic-ssl-lib' is added to the +`$ERL_TOP/configure' command line arguments unless `--enable-dynamic-ssl-lib' +has been explicitly passed. The defaults used by `$ERL_TOP/otp_build configure' +may change at any time without prior notice. + +The build system, including cross compilation configuration variables used, +may be subject to non backward compatible changes without prior notice. +Current cross build system has been tested when cross compiling some Linux/GNU +systems, but has only been partly tested for more esoteric platforms. The +VxWorks example file is highly dependent on our environment and is here more +or less only for internal use. + +Please submit any patches for cross compiling in a way consistent with this +system. All input is welcome as we have a very limited set of cross compiling +environments to test with. If a new configuration variable is needed, add it +to `$ERL_TOP/xcomp/erl-xcomp.conf.template', and use it in `configure.in'. +Other files that might need to be updated are: +- `$ERL_TOP/xcomp/erl-xcomp-vars.sh' +- `$ERL_TOP/erl-build-tool-vars.sh' +- `$ERL_TOP/erts/aclocal.m4' +- `$ERL_TOP/xcomp/README' +- `$ERL_TOP/xcomp/erl-xcomp-*.conf' +Note that this might be an incomplete list of files that need to be updated. + +General information on how to submit patches can be found at: + http://wiki.github.com/erlang/otp/submitting-patches + +======= Build and Install ===================================================== + + [1] + +Change directory into the top directory of the Erlang/OTP source tree. + + $ cd $ERL_TOP + +------- Build ----------------------------------------------------------------- + +In order to compile Erlang code, a small Erlang bootstrap system has to be +built, or an Erlang/OTP system of the same release as the one being built +has to be provided in the `$PATH'. The Erlang/OTP for the target system will +be built using this Erlang system, together with the cross compilation tools +provided. + +If you want to build using a compatible Erlang/OTP system in the `$PATH', +jump to [3]. + +-- Building a bootstrap system -- + + [2] + + $ ./configure --enable-bootstrap-only + $ make + +The `--enable-bootstrap-only' argument to `configure' isn't strictly necessary, +but will speed things up. It will only run `configure' in applications +necessary for the bootstrap, and will disable a lot of things not needed by +the bootstrap system. If you run `configure' without `--enable-boostrap-only' +you also have to run make as `make bootstrap'; otherwise, the whole system will +be built. + +-- Cross building the system -- + + [3] + + $ ./configure --build=<BUILD> --host=<HOST> [Other Configure Args] + $ make + +<BUILD> should equal the CPU-VENDOR-OS triplet of the system that you build +on. If you execute `$ERL_TOP/erts/autoconf/config.guess', it will in most +cases print the triplet you want to use for this. + +<HOST> is the system that you build for. It does not have to be a full +CPU-VENDOR-OS triplet, but can be. The full CPU-VENDOR-OS triplet will be +created by executing `$ERL_TOP/erts/autoconf/config.sub <HOST>'. If +`config.sub' fails, you need to be more specific. + +Pass the cross compilation variables as command line arguments to `configure' +using a `<VAR>=<VALUE>' syntax (or export them in the environment). Note that +you can *not* pass a configuration file using `--xcomp-conf=<FILE>' when you +invoke `configure' directly. The `--xcomp-conf=<FILE>' argument can only +be passed to `$ERL_TOP/otp_build configure'. + +`make' will verify that the Erlang/OTP system used when building is of the +same release as the system being built, and will fail if this is not the case. +It is possible, however not recommended, to force the cross compilation even +though the wrong Erlang/OTP system is used. This by invoking `make' like this: +`make ERL_XCOMP_FORCE_DIFFERENT_OTP=yes'. Note that this build might fail, +silently produce suboptimal code, or silently produce erroneous code. + +-- Installing -- + +You can either install using the installation paths determined by `configure' +[4], or install manually using [5]. + + [4] + + $ make install DESTDIR=<TEMPORARY_PREFIX> + +`make install' will install at a location specified when doing `configure'. +`configure' arguments specifying where the installation should reside are for +example: `--prefix', `--exec-prefix', `--libdir', `--bindir', etc. By default +it will install under `/usr/local'. You typically do not want to install your +cross build under `/usr/local' on your build machine. Using `DESTDIR' will +cause the installation paths to be prefixed by `$DESTDIR'. This makes it +possible to install and package the installation on the build machine without +having to place the installation in the same directory on the build machine as +it should be executed from on the target machine. + +When `make install' has finished, change directory into `$DESTDIR', package +the system, move it to the target machine, and unpack it. Note that the +installation will only be working on the target machine at the location +determined by `configure'. + +Installing manually: + + [5] + + $ make release RELEASE_ROOT=<RELEASE_DIR> + +`make release' will copy what you have built for the target machine to +`<RELEASE_DIR>'. The `Install' script will not be run. The content of +`<RELEASE_DIR>' is what by default ends up in `/usr/local/lib/erlang'. + +The `Install' script used when installing Erlang/OTP requires common Unix +tools such as `sed' to be present in your `$PATH'. If your target system +does not have such tools, you need to run the `Install' script on your +build machine before packaging Erlang/OTP. The `Install' script should +currently be invoked as follows in the directory where it resides +(the top directory): + `./Install [-cross] [-minimal|-sasl] <ERL_ROOT>' + where: + -minimal - Creates an installation that starts up a minimal amount + of applications, i.e., only `kernel' and `stdlib' are + started. The minimal system is normally enough. + -sasl - Creates an installation that also starts up the `sasl' + application. + -cross - For cross compilation. Informs the install script that it + is run on the build machine. + <ERL_ROOT> - The absolute path to the Erlang installation to use at run + time. This is often the same as the current working + directory, but does not have to be. It can follow any other + path through the file system to the same directory. +If neither `-minimal', nor `-sasl' is passed as argument you will be +prompted. + +You can now either: + + [6] + +* Decide where the installation should be located on the target machine, run + the `Install' script on the build machine, and package the installed + installation. The installation just need to be unpacked at the right + location on the target machine: + + $ cd <RELEASE_DIR> + $ ./Install -cross [-minimal|-sasl] <ABSOLUTE_INSTALL_DIR_ON_TARGET> + + [7] + +* Package the installation in <RELEASE_DIR>, place it wherever you want on + your target machine, and run the `Install' script on your target machine: + + $ cd <ABSOLUTE_INSTALL_DIR_ON_TARGET> + $ ./Install [-minimal|-sasl] <ABSOLUTE_INSTALL_DIR_ON_TARGET> + +-- Building with the `otp_build' script -- + + [8] + + $ cd $ERL_TOP + + [9] + + $ ./otp_build configure [--build=<BUILD>] [--host=<HOST>] \ + [--with-xcomp-conf=<FILE>] [Other Configure Args] + +If you have your cross compilation configuration in a file, pass it using the +`--xcomp-conf=<FILE>' command line argument. If not, pass the configuration +variables on the command line using a `<VAR>=<VALUE>' syntax (or in the +environment). + +`--build=<BUILD>', and `--host=<HOST>' are the same as described at [3]. +The `--xcomp-conf=<FILE>' argument causes `otp_build' to read the cross +compilation configuration from `<FILE>'. All of these arguments are in this +case optional, but `<BUILD>', and `<HOST>' must be given either by passing +`--build=<BUILD>' and `--host=<HOST>' on the command line, or by setting +`erl_xcomp_build=<HOST>', and `erl_xcomp_host=<HOST>' in `<FILE>' and +passing the `--xcomp-conf=<FILE>' argument. + +`otp_build configure' will configure both for the boostrap system on the +build machine and the cross host system. + + [10] + + $ ./otp_build boot -a + + 'otp_build boot -a' will first build a bootstrap system +for the build machine and then do the cross build of the system. + + [11] + + $ ./otp_build release -a <RELEASE_DIR> + +'otp_build release -a' will do the same as [5], and you will after this have +to do a manual install either by doing [6], or [7]. + +======== Currently used configuration variables =============================== + +Note that you cannot define arbitrary variables in a cross compilation +configuration file. Only the ones listed below will be guaranteed to be +visible throughout the whole execution of all `configure' scripts. Other +variables needs to be defined as arguments to `configure' or exported in +the environment. + +-------- `otp_build' only variables ------------------------------------------- + +Variables in this section are only used, when configuring Erlang/OTP for +cross compilation using `$ERL_TOP/otp_build configure'. + +NOTE! These variables currently have *no* effect if you configure using the +`configure' script directly. + +* erl_xcomp_build - Build system. + This value will be passed as `--build=$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: + `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_build' + If `erl_xcomp_build=guess', the build system will be guessed using: + `$ERL_TOP/erts/autoconf/config.guess'. + +* erl_xcomp_host - Cross host system. + This value will be passed as `--host=$erl_xcomp_host' argument to the + `configure' script. It does not have to be a full CPU-VENDOR-OS triplet, + but can be. The full CPU-VENDOR-OS triplet will be created by: + `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host' + +* erl_xcomp_configure_flags - Extra configure flags. + Extra flags to pass to the `configure' script. + +-------- Cross compiler and other tools to use -------------------------------- + +If the cross compilation tools are prefixed by `<HOST>-' you probably do +not need to set these variables (where `<HOST>' is what has been passed as +`--host=<HOST>' argument to `configure'). + +* CC - C compiler. + +* CFLAGS - C compiler flags. + +* STATIC_CFLAGS - Static C compiler flags. + +* CFLAG_RUNTIME_LIBRARY_PATH - C compiler runtime library path flag. + This flag should set a specific runtime library path for the shared + library at link time. Note that this is actually a linker flag, but it + needs to be passed via the compiler. + +* CPP - C pre-processor. + +* CPPFLAGS - C pre-processor flags. + +* CXX - C++ compiler. + +* CXXFLAGS - C++ compiler flags. + +* LD - Linker + +* LDFLAGS - Linker flags. + +-- Dynamic Erlang Driver linker flags. -- + +NOTE! Either define all or non of the DED_LD* variables. + +* DED_LD - Linker. + +* DED_LDFLAGS - Linker flags. + +* DED_LD_FLAG_RUNTIME_LIBRARY_PATH - Linker runtime library path flag. + This flag should set a specific runtime library path for the shared + library at link time. + +-- Other tools -- + +* RANLIB - ranlib + +* AR - ar + +-------- Cross System Root Locations ------------------------------------------ + +* erl_xcomp_sysroot - Absolute cross system root path. + The absolute path to the system root of the cross compilation + environment. Currently, the `crypto', `odbc', `ssh' and `ssl' + applications need the system root. These applications will be skipped + if the system root has not been set. The system root might be needed + for other things too. If this is the case and the system root has not + been set, `configure' will fail and request you to set it. + +* erl_xcomp_isysroot - Absolute cross include system root path. + The absolute path to the system root for includes of the cross + compilation environment. If not set, this value defaults to + `$erl_xcomp_sysroot', i.e., only set this value if the include system + root path is not the same as the system root path. + +-------- Optional feature, or bug tests --------------------------------------- + +These tests cannot (always) be done automatically when cross compiling. You +usually does not need to set these variables. Only set these if you really +know what you are doing. + +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_bigendian - yes|no + 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. No default value is used, i.e., `configure' will try to figure + this out automatically. + +* 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_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_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 less than 2.2) + used these signals and made them unusable by the ERTS. + +* 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_poll - yes|no (defaults to `no' on Darwin/MacOSX; otherwise, `yes') + If `yes', the target system must have a working `poll()' implementation + that also can handle devices. If `no', `select()' will be used instead of + `poll()'. + +* 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_putenv_copy - yes|no (defaults to `no') + If `yes', the target system must have a `putenv()' implementation that + stores a copy of the key/value pair. + +* erl_xcomp_reliable_fpe - yes|no (defaults to `no') + If `yes', the target system must have reliable floating point exceptions. + +* 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_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_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_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. + +* 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. + +=============================================================================== diff --git a/xcomp/README.xcomp b/xcomp/README.xcomp deleted file mode 100644 index 4df9226a96..0000000000 --- a/xcomp/README.xcomp +++ /dev/null @@ -1,25 +0,0 @@ -This directory contains configuration file templates and examples for -cross compiling Erlang/OTP.
