Hello all, I have exactly the same error like described in http://gcc.gnu.org/ml/gcc-help/2009-05/msg00323.html namely collect2: library libstdc++ -lsupc++ not found I have a POWER6 with AIX 6.1.2, for the build --disable-shared was used (i think this is the reason why this error does not show up in regular shared library builds). When i invoke g++ with both -v and -save-temps and then invoke the final collect2 step manually (using cut and paste) the link succeeds. According to my investigations, the reason for this kind of failure is * collect2 is executed via execvp in gcc.c resp. pex-unix.c * the link line (i.e. the collect2 invocation) contains -lstdc++ -lsupc++ since we are in the C++ realm. * The error now is, that -lstdc++ -lsupc++ is given in the execvp argument vector as one argument instead two separate arguments. * As a result the call to resolve_lib_name in collect2.c fails, since it can handle only one -lxxx per call and not multiple ones. Should i file a bug report and is there an easy resolution? Best regards Franz
