Note in the output below that as numpy is compiled, -m64 is shown on some lines, which is what I expect. But note also the messages about "wrong ELF class: ELFCLASS64" from the linker, indicating to me the linker is not expecting to find 64-bit objects. All the libraries in the directory /export/home/drkirkby/sage-4.5.alpha0/local/lib are 64-bit. Someone worked around this on OS X by creating a script called 'gcc_fake', with this content #!/bin/bash /usr/bin/gcc -m64 $@ If a 64-bit build was going to be done, this was remaned to 'gcc' and put in the path first before building numpy. Once numpy was built, the script can be deleted. All the script does is basically invoke gcc with the -m64 option, which is making me think that -m64 is being missed somewhere. I just deleted this gcc_fake, as it had a hard-coded path. I then created it dynamically, so the path of the real gcc does not need to be /usr/bin/gcc. Doing that, I can build numpy 64-bit on OpenSolaris. But of course this is a hack, and I'd rather avoid the hack if possible. BTW, if it would help, I could create you an account on this machine and test it yourself. I'm not trying to get out of doing the work, but the offer is there.
