Can someone please tell me what I am doing wrong?
When building the 32bit libcillkrts you are linking against the 64-bit libstdc++. It's right there on your command line: /export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so. If that argument is needed at all, it needs to be /export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so (note added /32 in there). I guess the question is where the argument is coming from. I must admit that I don't know. Is it in some environment variable? Ian
