Build failure on OSX

[joehuchette]

Looking over the repo, it appears that the issue is likely with a missing gmp header. However, I'm not sure how to track it down on OSX; AFAICT Homebrew doesn't have a dev version of gmp like pacman and friends.

Yes, Julia installs GMP libraries but not necessarily GMP headers :(
On Travis, both GMP headers and libraries were already there for Mac and for Linux I just had to add the libgmp-dev package.
Windows isn't supported yet and I thought all Mac would have the headers but apparently this is not the case :'(

Maybe I should just download GMP, unzip it and link to the headers like that. This sounds ugly since it may not be same version as the version of the libraries already installed by Julia but this could also work for Windows... Or maybe I should check how Julia handles the GMP installation and try to do something similar

It seems that what Julia does is either use GMP from a package manager of build GMP 6.1.0 from scratch (that might be the solution used for Windows).
If I can find a way to check whether the headers are available, I could just download GMP 6.1.0 if it is not the case.
Or maybe the easiest way would be to patch cddlib to let it handle it ^^ For instance GLPK.jl does not seem to worry to much about GMP in its deps/build.jl because I guess that glpk does all the job

I just looked more closely at your error. It seems that you have GMP and the issue is rather that you do not have -lgmp in the link commands that fail.
Which version of CDDLib.jl are you using ? Did you do Pkg.checkout("CDDLib") ?

Wow, I could've sworn I tried this before...it's working now (after checking out)! Thanks a bunch.
