c++

Modify the cross-compiling shell script to configure GCC for building GCC with C++ support when building its second (i.e., final) version.

Compiling a most-trivial C++ program used to work with GCC 4.2 and 4.3 (and the resulting binaries would also work), but linking fails with GCC SVN trunk:

$ $TARGET-g++ -Wall a.cc -lpthread

collect2: ld returned 1 exit status

Whether this defect report also applies to a natively-build GCC from SVN trunk has not yet been checked.

Thomas Schwinge suspects the problem to be a configuration issue of a GCC helper library, whose configuration setup has changed after GCC 4.3.

The need for -lpthread is another story. See the Debian glibc patches repository for details.

For GCC trunk:

Debian package has patches (for 4.3). Some have been forwarded upstream. (And have been ignored.) Thomas Schwinge is working on getting them integrated.

Additionally:

  • Configure fragments that have *linux* cases might/should often contain those for us (and GNU/k*BSD) as well.

    • libgcc/configure.ac might need to be aligned for us to the *linux* cases. As well as at the end of libgcc/config.host. Check.

      checking whether decimal floating point is supported... no
checking whether fixed-point is supported... no

    • libgomp/configure.tgt

  • libmudflap.

  • C++.
