Description Faker Moatamri 2009-04-17 12:31:28 UTC

The build works with gcc 4.4.0 but the checktests and the regression tests doesn't pass in the optimized mode.

Comment 1 Mathieu Lacage 2009-04-20 02:52:56 UTC

On a system with multiple compilers installed, we need to link explicitely against the compiler's c++ library:

For example:
bash-3.2$ g++-4.4.0 -print-file-name=libstdc++.so
/usr/local/lib/gcc/x86_64-unknown-linux-gnu/4.4.0/../../../../lib64/libstdc++.so

Would it be possible/would it make sense to use -rpath with the above command to link against the c++ stl library with waf ?

a patch

Patch implementing Mathieu's suggestion.  No idea if this solves the problem.  I don't think I have the correct environment to test.

Then again, Mathieu says rpath, so could be this patch instead.

patch using xxx_LIBRARY_PATH

Then again, if this works it is probably more portable.
