This problem is also true for Sun Solaris (which I tried the same
thing on). We develop on Mac's
First, you need to install libgmp - Math::GMP is just a wrapper
around that. Ideally, Math::GMP's Makefile.PL would detect that
libgmp isn't present, and complain with an informative message
instead of just failing to compile, but it doesn't. :-( That would
absolutely be a problem worth being reported to the Math::GMP
maintainer.
Installing libgmp *might* be a bit of an adventure if you're using an
Intel Mac. Google "libgmp intel mac" for details - the messages I
found relate to gmp 4.2.0 and are dated April '06; the latest release
is 4.2.1, which was released in May '06, so I don't know if those
problems are still relevant or not. I'd try it "out of the box"
first, and then read about the problems if that fails.
I'm on an old G4, so I used the standard "configure; make; make
check; sudo make install" routine which built & installed libgmp
without any problems.
Once you've installed libgmp, you're ready to install Math::GMP. To
do that, I needed to add to the linker flags that CPAN.pm would use.
(You may not need to do this on your Solaris machines.)
From inside the CPAN shell:
cpan> o conf makepl_arg "LDDLFLAGS='-bundle -undefined
dynamic_lookup -read_only_relocs suppress'"
The '-read_only_relocs suppress' is the important one here - the rest
are there because I couldn't figure out how to *add* to the linker
flags that Perl uses, instead of *replacing* the whole set of them. :-(
Once I'd done that, I got a clean compile and all the self-tests passed:
