I've reproduced this on my system. I really don't think this is a
'gmp' issue, and I would not (yet) start fooling around with fink or
MacPorts. The problem seems more basic: the fact that "-lcrt0.o" is
the issue means (to me, at least) that the tool chain is really
In the future, please include this information, since it will help
diagnose this kind of problem:
- hardware platform (processor, if known)
- OS version
- GAP version and (if it's about a package) package version
I am running on a Mac Pro (Dual Quad Xeon, 3GHz), Mac OS X 10.4.11.
I tried this with Gap 4.4.10, and nq 2.2.
I find that my locally-built GMP is built as a 64-bit library, while
nq is built 32-bit. I think that is the problem (GMP seems to insist
on 64-bit builds if it's possible).
Let us know what the above information is, and whether you built GMP
yourself (and if not, where it came from).
