in thread Math::GMP won't install on Darwin

Are there any newer insights about this issue? I tried gcc 3.3 and gcc 4.0 from the latest XCode 2.3 release, but both failed in exactly the same way. I need to build Math::GMP for a demo installation of a project requiring Net::SSH, and currently I'm stuck. Thanks in advance, Peter Eckel.

    I haven't had time to get back to this problem since my last posting.

    What's the exact problem ? Sorry ... I've gone back through this thread but I'm not sure what the exact issue is - and rt.cpan.org seems to be down at the moment so I can't even get to the bug reports. I did see an earlier suggestion that compiler bugs may be the problem - but my understanding is that if 'make check' passed all tests (when building the GMP library) then you haven't got any compiler bugs. If GMP has been successfully built and installed then I feel there shouldn't be much of a problem in getting Math::GMP installed ... though, admittedly, I know stuff-all about Macs.

    I could speculate about what the problem could be ... but it's probably quicker if someone provides a refresh of the situation.

    Cheers,

      OK, so here's what I did.

      1. Downloaded, configured and compiled libgmp 4.2.1 using gcc 4.0.1 (the latest version from XCode).

      2. "make check" on libgmp. No errors.

      3. Installed libgmp (make install), again, no errors.

      4. Tried to install Math::GMP using CPAN. This fails:

      6. Switch gcc to version 3.3

      8. make check (no errors)

      9. Tried to install Math::GMP. Same result as above.

      Please feel free to contact me if you need any further information. I'll be glad to help.

      Thanks,

      Peter.

        There are some ideas on things to try in the thread called "how do I force PIC code in libgmp.a on MacOSX (Intel)...?" beginning at http://swox.com/list-archives/gmp-bugs/2006-April/000341.html. Unfortunately it doesn't seem to resolve the problem - beyond the suggestion that you revert to GMP-4.1.4 (which should be quite adequate for your needs ... assuming that solution does, in fact, work).

        I'm puzzled by the reference to 'modelo.o' (which I can't find anywhere in any of my GMP builds), and by the 'cc' (as opposed to 'gcc') call you report just before the failure occurs. I wonder whether the 'cc' call might have something to do with the error, though the thread I referred to above suggests that it has more to do with the 'bundle' switch ... and I have no idea what that switch does, or why it is being invoked.

        My only other idea is to build GMP as a shared library (./configure --disable-static --enable-shared) .... and, if linking to the import lib still produces the same error, then amend the Math::GMP source so that it links directly to the GMP '.so'. (I have no idea whether that will help in this instance ... it's just something I would try.)

        Cheers,
        Rob
