-Versions Known NOT to Work
---------------------------
+*   GNU `autoconf` of at least version 2.59. Note that `autoconf` is not
+    needed when building an unmodified version of the released source.
 
-*   Suse linux 9.1 is shipped with a patched GCC version 3.3.3, having the
-    rpm named `gcc-3.3.3-41`. That version has a serious optimization bug
-    that makes it unusable for building the Erlang emulator. Please
-    upgrade GCC to a newer version before building on Suse 9.1. Suse Linux
-    Enterprise edition 9 (SLES9) has `gcc-3.3.3-43` and is not affected.
+#### Building on OS X ####
 
-*   `gcc-4.3.0` has a serious optimizer bug. It produces an Erlang emulator
-    that will crash immediately. The bug is supposed to be fixed in
-    `gcc-4.3.1`.
+*   Xcode -- Download and install via the Mac App Store.
+    Read about [Building on a Mac][] before proceeding.
 
-*   FreeBSD had a bug which caused `kqueue`/`poll`/`select` to fail to detect
-    that a `writev()` on a pipe has been made. This bug should have been fixed
-    in FreeBSD 6.3 and FreeBSD 7.0. NetBSD and DragonFlyBSD probably have or

+*   An `install` program that can take multiple file names.
 
-*   `getcwd()` on Solaris 9 can cause an emulator crash. If you have
-    async-threads enabled you can increase the stack size of the
-    async-threads as a temporary workaround. See the `+a` command-line
-    argument in the documentation of `erl(1)`. Without async-threads the
-    emulator is not as vulnerable to this bug, but if you hit it without
-    async-threads the only workaround available is to enable async-threads
-    and increase the stack size of the async-threads. Sun has however

 ### Configuring ###
 
-Step 3: On some platforms Perl may behave strangely if certain locales are
-set, so optionally you may need to set the LANG variable:
-
-    # Bourne shell
-    $ LANG=C; export LANG
+Run the following commands to configure the build:
 
-or
+    $ ./configure [ options ]
 
-    # C-Shell
-    $ setenv LANG C
+> *NOTE*: If you are building Erlang/OTP from git you will need to run `./otp_build autoconf` to generate
+> the configure scripts.
 
-Step 4: Run the following commands to configure the build:
+By default, Erlang/OTP release will be installed in `/usr/local/{bin,lib/erlang}`.
+If you for instance don't have the permission to install in the standard location,
+ you can install Erlang/OTP somewhere else. For example, to install in
+`/opt/erlang/%OTP-VSN%/{bin,lib/erlang}`, use the `--prefix=/opt/erlang/%OTP-VSN%` option.
 
-    $ ./configure  [ options ]
+On some platforms Perl may behave strangely if certain locales are

-Step 5: Build the Erlang/OTP package.
+Build the Erlang/OTP release.

+
+### Testing ###
+
+Before installation you should test whether your build is working properly
+by running our smoke test. The smoke test is a subset of the complete Erlang/OTP test suites.
+First you will need to build and release the test suites.
+
+    $ make release_tests
+
+This creates an additional folder in `$ERL_TOP/release` called `tests`.
+Now, it's time to start the smoke test.
+
+    $ cd release/tests/test_server
+    $ $ERL_TOP/bin/erl -s ts install -s ts smoke_test batch -s init stop

-Let us go through them in some detail.
+### Running ###
+
+You should now have a working release of Erlang/OTP!
+Jump to [System Principles][] for instructions on running Erlang/OTP.
+
+
+### How to Build the Documentation ###
+
+Make sure you're in the top directory in the source tree.
+
+    $ cd $ERL_TOP
+
+If you have just built Erlang/OTP in the current source tree, you have
+already ran `configure` and do not need to do this again; otherwise, run
+`configure`.
+
+    $ ./configure [Configure Args]
+
+When building the documentation you need a full Erlang/OTP-%OTP-VSN% system in
+the `$PATH`.
+
+    $ export PATH=$ERL_TOP/bin:$PATH     # Assuming bash/sh
+
+Build the documentation.

+    $ make docs
+
+#### Build Issues ####
+
+We have sometimes experienced problems with Oracle's `java` running out of
+memory when running `fop`. Increasing the amount of memory available
+as follows has in our case solved the problem.
+
+    $ export FOP_OPTS="-Xmx<Installed amount of RAM in MB>m"
+
+More information can be found at
+*   <http://xmlgraphics.apache.org/fop/0.95/running.html#memory>.
+
+
+### How to Install the Documentation ###
+
+The documentation can be installed either using the `install-docs` target,
+or using the `release_docs` target.
+
+*   If you have installed Erlang/OTP using the `install` target, install
+    the documentation using the `install-docs` target. Install locations
+    determined by `configure` will be used. `$DESTDIR` can be used the
+    same way as when doing `make install`.
+
+        $ make install-docs
+
+*   If you have installed Erlang/OTP using the `release` target, install
+    the documentation using the `release_docs` target. You typically want
+    to use the same `RELEASE_ROOT` as when invoking `make release`.
+
+        $ make release_docs RELEASE_ROOT=<release dir>
+
+
+### Accessing the Documentation ###
+
+After installation you can access the documentation by
+
+*   Reading man pages. Make sure that `erl` is referring to the
+    installed version. For example `/usr/local/bin/erl`.
+    Try viewing at the man page for Mnesia
+
+        $ erl -man mnesia
+
+*   Browsing the html pages by loading the page `/usr/local/lib/erlang/doc/erlang/index.html`
+    or `<BaseDir>/lib/erlang/doc/erlang/index.html` if the prefix option has been used.
+
+
+### How to Install the Pre-formatted Documentation ###
+
+Pre-formatted [html documentation][] and [man pages][] can be downloaded from
+* <http://www.erlang.org/download.html>.
+
+Extract the html archive in the installation directory.
+
+    $ cd <ReleaseDir>
+    $ tar -zxf otp_html_%OTP-VSN%.tar.gz
+
+For `erl -man <page>` to work the Unix manual pages have to be
+installed in the same way, i.e.
+
+    $ cd <ReleaseDir>
+    $ tar -zxf otp_man_%OTP-VSN%.tar.gz
+
+Where `<ReleaseDir>` is
+
+*   `<PrefixDir>/lib/erlang` if you have installed Erlang/OTP using
+    `make install`.
+*   `$DESTDIR<PrefixDir>/lib/erlang` if you have installed Erlang/OTP
+    using `make install DESTDIR=<TmpInstallDir>`.
+*   `RELEASE_ROOT` if you have installed using
+    `make release RELEASE_ROOT=<ReleaseDir>`.
+
+
+Advanced configuration and build of Erlang/OTP
+----------------------------------------------
+
+If you want to tailor your Erlang/OTP build and installation, please read
+on for detailed information about the individual steps.
+
+### make and $ERL\_TOP ###
+
+All the makefiles in the entire directory tree use the environment
+variable `ERL_TOP` to find the absolute path of the installation. The
+`configure` script will figure this out and set it in the top level
+Makefile (which, when building, it will pass on). However, when
+developing it is sometimes convenient to be able to run make in a
+subdirectory. To do this you must set the `ERL_TOP` variable
+before you run make.
 
-Step 4 runs a configuration script created by the GNU autoconf utility, which
+For example, assume your GNU make program is called `make` and you
+want to rebuild the application `STDLIB`, then you could do:

+
+where `<Dir>` would be what you find `ERL_TOP` is set to in the top level
+Makefile.
+
+### otp\_build vs configure/make ###
+
+Building Erlang/OTP can be done either by using the `$ERL_TOP/otp_build`
+script, or by invoking `$ERL_TOP/configure` and `make` directly. Building using
+`otp_build` is easier since it involves fewer steps, but the `otp_build` build
+procedure is not as flexible as the `configure`/`make` build procedure. The binary
+releases for Windows that we deliver are built using `otp_build`.

 checks for system specific features and then creates a number of makefiles.

+
+#### How to Build a Debug Enabled Erlang RunTime System ####
+
+After completing all the normal building steps described above a debug
+enabled runtime system can be built. To do this you have to change
+directory to `$ERL_TOP/erts/emulator`.
+
+In this directory execute:
+
+    $ make debug FLAVOR=$FLAVOR
+
+where `$FLAVOR` is either `plain` or `smp`. The flavor options will
+produce a beam.debug and beam.smp.debug executable respectively. The
+files are installed along side with the normal (opt) versions `beam.smp`
+and `beam`.
+
+To start the debug enabled runtime system execute:
+
+    $ $ERL_TOP/bin/cerl -debug
 
-    $ bin/erl
-    Erlang/OTP %OTP-REL% [erts-%ERTS-VSN%] [source] [smp:4:4] [async-threads:0] [kernel-poll:false]
+The debug enabled runtime system features lock violation checking,
+assert checking and various sanity checks to help a developer ensure
+correctness. Some of these features can be enabled on a normal beam
+using appropriate configure options.
 
-    Eshell V%ERTS-VSN%  (abort with ^G)
-    1> _
+There are other types of runtime systems that can be built as well
+using the similar steps just described.
 
-#### Installing ####
+    $ make $TYPE FLAVOR=$FLAVOR
+
+where `$TYPE` is `opt`, `gcov`, `gprof`, `debug`, `valgrind`, or `lcnt`.
+These different beam types are useful for debugging and profiling
+purposes.
 
-Step 6 is optional. It installs Erlang/OTP at a standardized location (if you
-change your mind about where you wish to install you can rerun step 4,
-without having to do step 5 again).

-### Building in Git ###
-
-When building in a Git working directory you also have to have a GNU `autoconf`
-of at least version 2.59 on your system, because you need to generate the
-`configure` scripts before you can start building.
-
-The `configure` scripts are generated by invoking `./otp_build autoconf` in
-the `$ERL_TOP` directory. The `configure` scripts also have to be regenerated
-when a `configure.in` or `aclocal.m4` file has been modified. Note that when

-content, and you may therefore have to regenerate the `configure` scripts

-> *NOTE*: Running `./otp_build autoconf` is **not** needed when building
-> an unmodified version of the released source.
-
-Other useful information can be found at our github wiki:
-<http://wiki.github.com/erlang/otp>
-
-### make and $ERL\_TOP ###
-
-All the makefiles in the entire directory tree use the environment
-variable `ERL_TOP` to find the absolute path of the installation. The
-`configure` script will figure this out and set it in the top level
-Makefile (which, when building, it will pass on). However, when
-developing it is sometimes convenient to be able to run make in a
-subdirectory. To do this you must set the `ERL_TOP` variable
-before you run make.
-
-For example, assume your GNU make program is called `make` and you
-want to rebuild the application `STDLIB`, then you could do:
-
-    $ cd lib/stdlib; env ERL_TOP=<Dir> make
-
-where `<Dir>` would be what you find `ERL_TOP` is set to in the top level
-Makefile.
-
-The Erlang/OTP Documentation
-----------------------------
-
-### How to Build the Documentation ###
-
-Before you can build the documentation you need to either [native build][]
-or [cross build][] the Erlang/OTP system. After this you can build the
-documentation as follows.
-
-    $ cd $ERL_TOP
-    $ make docs
-
-The documentation can be installed either using the `install-docs` target,
-or using the `release_docs` target.
-
-*   If you have installed Erlang/OTP using the `install` target, install
-    the documentation using the `install-docs` target. Install locations
-    determined by `configure` will be used. `$DESTDIR` can be used the
-    same way as when doing `make install`.
-
-        $ make install-docs
-
-*   If you have installed Erlang/OTP using the `release` target, install
-    the documentation using the `release_docs` target. You typically want
-    to use the same `RELEASE_ROOT` as when invoking `make release`.
-
-        $ make release_docs RELEASE_ROOT=<release dir>
-
-#### Build Issues ####
-
-We have sometimes experienced problems with Sun's `java` running out of
-memory when running `fop`. Increasing the amount of memory available
-as follows has in our case solved the problem.
-
-    $ export FOP_OPTS="-Xmx<Installed amount of RAM in MB>m"
-
-More information can be found at
-<http://xmlgraphics.apache.org/fop/0.95/running.html#memory>.
-
-### How to Install the Pre-formatted Documentation ###
-
-Pre-formatted [html documentation][] and [man pages][] can be downloaded at
-<http://www.erlang.org/download.html>.
-
-For some graphical tools to find the on-line help you have to install
-the HTML documentation on top of the installed OTP applications, i.e.
-
-    $ cd <ReleaseDir>
-    $ gunzip -c otp_html_%OTP-VSN%.tar.gz | tar xf -
-
-For `erl -man <page>` to work the Unix manual pages have to be
-installed in the same way, i.e.
-
-    $ cd <ReleaseDir>
-    $ gunzip -c otp_man_%OTP-VSN%.tar.gz | tar xf -
-
-Where `<ReleaseDir>` is
-
-*   `<PrefixDir>/lib/erlang` if you have installed Erlang/OTP using
-    `make install`.
-*   `$DESTDIR<PrefixDir>/lib/erlang` if you have installed Erlang/OTP
-    using `make install DESTDIR=<TmpInstallDir>`.
-*   `RELEASE_ROOT` if you have installed using
-    `make release RELEASE_ROOT=<ReleaseDir>`.
-
-Support for SMP (Symmetric Multi Processing)
---------------------------------------------
-
-An emulator with SMP support will be built by default on most platforms
-if a usable POSIX thread library or native Windows threads is found.
 
-You can force building of an SMP emulator, by using
-`./configure --enable-smp-support`. However, if configure does not
-automatically enable SMP support, the build is very likely to fail.
+### Running ###
 
-Use `./configure --disable-smp-support` if you for some reason do not
-want to have the emulator with SMP support built.
-
-If SMP support is enabled, support for threaded I/O will also be turned on
-(also in the emulator without SMP support).
-
-The `erl` command will automatically start the SMP emulator if the
-computer has more than one logical processor. You can force a start
-of the emulator with SMP support by passing `-smp enable` as
-command line arguments to erl, and you can force a start of the
-emulator without SMP support by passing `-smp disable`.
