So I downloaded the source of the same version of gmp that I have and copied gmp.h from there to the directory where I was compiling Math::GMP. That allowed me to do the make

 cp /exlibris/sfx_ver/src-v3/gmp-4.1.4/gmp.h .
make

But now I get an error during the make test!

This is my environment:
SunOS lakeview 5.9 Generic sun4u sparc SUNW,Ultra-80
perl 5.8.6
cc: Forte Developer 7 C 5.4 2002/03/09
GNU Make 3.80

Any ideas? (I wonder if should I try to use my gcc? How can I tell make to use gcc instead of Solaris cc?)

Thanks

Update - Problem solved!

The key is to have GMP compiled from source, using the same compiler as perl and with 32bits binaries.

This is what I did:

1. Downloaded GMP (http://www.swox.com/gmp/) and compiled it.

2. Run Makefile.PL pointing to the recently compiled GMP.
