Hi, I have compiled gcc-4.4.0 on AIX 5.3 (using my current gcc-4.3.3 and GNU toolchain) with no problem (I also compiled PPL and CLoog). I use the AIX linker and used --disabled shared. However, when trying to compile a simple c++ program, I get this error: collect2: library libstdc++ -lsupc++ not found That's very strange, because 4.3.3 had no problem finding these libraries. My GNU toolchain and libs are in a local directory and are very parallel: $PREFIXGNU/lib/gcc/powerpc-ibm-aix5.3.0.0/4.3.3 contains: finclude/ include-fixed/ libgcc.a libgomp.a libgomp.spec libstdc++.la* libsupc++.la* pthread/ include/ install-tools/ libgcov.a libgomp.la* libstdc++.a libsupc++.a ppc64/ and $PREFIXGNU/lib/gcc/powerpc-ibm-aix5.3.0.0/4.4.0 contains the same file names. gcc-4.4.0 was configured with: bash-2.05a$ gcc -v Using built-in specs.

I don't understand the problem with 4.4.0. Thanks for your help, Eric
