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:
List of primary targets for GCC 4.8
List of secondary targets for GCC 4.8
List of all the targets that reported build results during 2011 (collected from the 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:
- To claim a target, simply write down your name in the 'Tester' column.
- Once your target is built:
- Write PASS or FAIL in the 'Status' column.
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.
If you find a bug during the build, please file it in Bugzilla and add it as a dependency to the meta-bug 44433.
The criteria for switching the default to C++ is:
- All the primary targets work.
- All the secondary targets work.
- 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.
