He ran into a situation where he tried to move the binary from one machine to another and got an Illegal instruction fault. gmp is built in (i.e. not a shared library) on these systems. He put in a configure switch --enable/--disable-common-binary governing this. Even when this is disabled, host=mingw32 defaults to i386. One can do --host=i686-pc-mingw32 to get a higher capability build if desired. This is of course cross compiling so no cpu detection is pertinent. On a separate front, am a little puzzled why --build fails in place of --host. I think there should be a better way to handle this, and it needs extending to any system building the local gmp. Suggestions? BTW, where is open-axiom re: compiling under wine? I did ask about wine running win64 binaries, and it is very experimental. I'd need root on a amd64 box anyway to support it, which alas I do not have. If you can suggest a way I might try to extend gcl support here before release, I'd love to hear it.
