Strange. I'm looking at the commit history at github and I see no gmp.h in the repository in commits as old as 2009. Am I misunderstanding or not noticing something?

There's one in ghc/libraries/integer-gmp/gmp/gmp.h On Apr 26, 2013, at 10:08 AM, Jan Stolarek wrote:

Thanks to everyone for the comments. I didn't try to fix the build system. I took the easy approach and just used macports to install gmp on my system and added macports' lib and include paths to the C_INCLUDE_PATH and LIBRARY_PATH variables. The build succeeded now. Maybe I should add a note to the wiki page on build prerequisites for mac os x regarding this issue? Or will the build be fixed to pick up gmp from the in-tree GMP? -Andi On Fri, Apr 26, 2013 at 11:55 AM, Páli Gábor János wrote:

As far I know, there is an "in-tree" GMP packaged as a tarball under the ghc/libraries/integer-gmp/tarball directory. GNU/Linux can pick up the gmp headers and libraries because they are some expected location (perhaps in /usr/include and /usr/lib), while FreeBSD cannot, because GMP is installed as a third-party software and resides under some prefix, which is usually /usr/local/{include,lib} so it would fall back to the in-tree version.

The solution is use the --with-gmp-includes and --with-gmp-libraries flags for the "configure" script. The x86 FreeBSD builder fails because these flags are not specified and it cannot pick up the in-tree GMP any more (I have mentioned Ian this problem, but probably he did not have time to fix this up), while the x86_64 FreeBSD builder works because it picks up the system GMP due to these flags.

Actually, the x86_64 FreeBSD builder were also able to pick up the in-tree GMP, but unfortunately it causes some linking error if I recall this correctly (c.f. #4022).
