= Building GCC in C++ =
This page documents the testing plan and status of all the targets that should be tested with C++.  This page is maintained by Diego Novillo ( dnovillo@google.com ).

If you have access to any of the targets mentioned in this page, and can spare a few machine cycles, you can help by testing your target in C++ mode.  Setting the build in C++ mode is trivial:

 * See if your target is still in need of testing (see the table below).
 * Get the most recent version of trunk via SVN or Git

{{{
$ svn co svn://gcc.gnu.org/svn/gcc/trunk
}}}
 * Configure the build with the flag {{{--enable-build-with-cxx}}}

{{{
$ mkdir bld && cd bld && ../gcc/configure --enable-build-with-cxx [... plus any other configure flags for your target ...]
}}}
 * Launch the build

{{{
$ make
}}}
 * Once the build finishes, please record its status in the table below and send mail to gcc@gcc.gnu.org and dnovillo@google.com .

= C++ Build Status =
This table contains targets that should be tested in C++ mode.  The target list was gathered from three sources:

 1. List of [[http://gcc.gnu.org/gcc-4.8/criteria.html|primary targets for GCC 4.8]]
 1. List of [[http://gcc.gnu.org/gcc-4.8/criteria.html|secondary targets for GCC 4.8]]
 1. List of all the targets that reported build results during 2011 (collected from the [[http://gcc.gnu.org/ml/gcc-testresults/|GCC test results mailing list archives]].

The list is sorted by target ''popularity''.  I defined ''popularity'' based on the number of postings made to gcc-testresults@gcc.gnu.org during all of 2011.  It is an imperfect metric, but it captures the commonly built and reported targets.

How to work with this list:

 1. To claim a target, simply write down your name in the 'Tester' column.
 1. Once your target is built:
  1. Write PASS or FAIL in the 'Status' column.
  1. Send mail to gcc@gcc.gnu.org and dnovillo@google.com describing the results you obtained or simply write them down in the 'Notes' column.

 1. If you find a bug during the build, please file it in [[http://gcc.gnu.org/bugzilla|Bugzilla]] and add it as a dependency to the meta-bug [[http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44433|44433]].

The criteria for switching the default to C++ is:

 1. All the primary targets work.
 1. All the secondary targets work.
 1. Targets with a popularity index larger than 0.01% work.

If you have access to a target not referenced in this table, feel free to add it and post results here.
