Mac Forum / Programming / Perl / August 2006

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:

    cpan> test Math::GMP

You just have to install those missing modules one by one. Some are software
libraries.
You just have to go to get those libs and install them by following the
instruction.

I have done this before. It took me quite a while to finish it.
But it can be done.

Since I have done this one year ago, I could not remember the details.
But this module has worked on my machine since then.
