Hi.

I have no experience with gmp, and little with c++. However, I had been looking at ld today, and thought I would try a few things.

Briefly, I downloaded gmp 5.x from gnu.org, compiled it with your .configure line (into ~/gmp), ran make, make check, make install. Then I created a script, s1, to try the test code compile, link, execute. The (lengthy) results are below in 3 sections: my environment, the script, and the "link trace" compile, link, execute.

Code:

OS, ker|rel, machine: Linux, 2.6.26-2-686, i686
Distribution        : Debian GNU/Linux 5.0 
g++ (Debian 4.3.2-1.1) 4.3.2
GNU ld (GNU Binutils for Debian) 2.18.0.20080103

At first I thought the link had included everything in libgmp.a, but there are 450+ entries (according to nm | grep T | wc, and ar t | wc), so I concluded it was a selective link.

I am not using OS X, but I'd guess it's worth a try to do it this way if you cannot install into /lib, /usr/lib.

Good luck ... cheers, drl
