How to enable php-gmp on Mac OS X 10.6.6? (no macports)

Question

I want to enable my php-gmp and I don\'t want to use macports because I use homebrew.

First I

brew install gmp

and I go

Answer 1

Php-gmp is incompatible with GMP 5.0.1. This is a known bug, reported on bugs.php.net over a year ago. Check the comments on the bug to see if there's a workaround that works for you. If not, and if homebrew doesn't have a GMP 4.x package you can install instead, I think you're stuck building a copy of GMP 4.x manually. :-(

Answer 2

If you have the homebrew-php tap installed, you can now do:

$ brew install php55 --with-gmp
