`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).
+Testing the cross compiled system
+--------------------------------------
+Some of the tests that come with erlang use native code to test. This means
+that when cross compiling erlang you also have to cross compile test suites
+in order to run tests on the target host. To do this you first have to release
+the tests as usual.
+
+ $ make release_tests
+
+or
+
+ $ ./otp_build tests
+
+The tests will be released into `$ERL_TOP/release/tests`. After releasing the
+tests you have to install the tests on the build machine. You supply the same
+xcomp file as to `./otp_build` in (9).
+
+ $ cd $ERL_TOP/release/tests/test_server/
+ $ $ERL_TOP/bootstrap/bin/erl -eval 'ts:install([{xcomp,"<FILE>"}])' -s ts compile_testcases -s init stop
+
+You should get a lot of printouts as the testcases are compiled. Once done you
+should copy the entire `$ERL_TOP/release/tests` folder to the cross host system.
+
+Then go to the cross host system and setup the erlang installed in (4) or (5)
+to be in your `$PATH`. Then go to what previously was
+`$ERL_TOP/release/tests/test_server` and issue the following command.
+
+ $ erl -s ts install -s ts run all_tests -s init stop
+
+The configure should be skipped and all tests should hopefully pass. For more
+details about how to use ts run `erl -s ts help -s init stop`

+## the variables needed below. Then pass the path to the copy of this file as
+## an argument to `otp_build' in the configure stage:
+## `otp_build configure --xcomp-conf=<FILE>'
+## -----------------------------------------------------------------------------
+
+## 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.
+
+## -- Variables for `otp_build' Only -------------------------------------------
+
+## Variables in this section are only used, when configuring Erlang/OTP for
+## cross compilation using `$ERL_TOP/otp_build configure'.
+
+## *NOTE*! These variables currently have *no* effect if you configure using
+## the `configure' script directly.
+
+# * `erl_xcomp_build' - The build system used. This value will be passed as
+# `--build=$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
+# `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_build'. If set to `guess',
+# the build system will be guessed using
+# `$ERL_TOP/erts/autoconf/config.guess'.

+
+# * `erl_xcomp_host' - Cross host/target system to build for. 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

+# `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host'.

+# `configure' script.
+erl_xcomp_configure_flags=--without-termcap
+
+## -- Cross Compiler and Other Tools -------------------------------------------
+
+## 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').

+
+## -- Cross System Root Locations ----------------------------------------------
+
+# * `erl_xcomp_sysroot' - 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

+# has not been set, `configure' will fail and request you to set it.
+erl_xcomp_sysroot="$DSO_SYSROOT_POWERPC"
+
+# * `erl_xcomp_isysroot' - The absolute path to the system root for includes
+# of the cross compilation environment. If not set, this value defaults

+# root path is not the same as the system root path.

+
+## -- 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.
+
