This is a clue: Configured with: ../gcc-4.2.1/configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/sys/usr/local --bindir=/sys/usr --enable-threads --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.3.0.0 : (reconfigured) ../gcc-4.2.1/configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/sys/usr/local --with-slibdir=/sys/usr/lib --enable-threads --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.3.0.0 So, you configured and built gcc without specifying the dir for the shared libgcclibrary, and you then reconfigured with one.

It should be in /sys/usr/local/lib/libstdc++. Is it? Andrew.
