That's the answer I was hoping not to get :-) I can compile it fine as a 32 bit app. For example, this is my configure: /usr/src/gcc-10.2.0/configure --enable-languages=c,c++ --disable-werror --disable-libstdcxx-pch --with-cpu=power7 --disable-bootstrap --without-isl My interest was to create a pure 64-bit environment, and I spent a lot of hours trying! Is there a way to build 64 bit GCC on AIX? Thanks to all for the responses! Randal
