Description leonbaum2 2012-09-08 14:32:10 UTC 
On a fresh gentoo install, ghc is failing to compile because it can't find ffi.h.

# file /usr/lib64/libffi-3.0.11/include/ffi.h
/usr/lib64/libffi-3.0.11/include/ffi.h: ASCII English text

I've attached emerge --info ghc and the build.log.



Reproducible: Always

I get a similar error on a fresh ~ppc64 install, this time it is:

/var/tmp/portage/dev-lang/ghc-7.4.2/temp/ghc29476_0/ghc29476_0.c:4:17:
     fatal error: ffi.h: No such file or directory

Comment 4 Sergei Trofimovich (RETIRED) gentoo-dev 2013-02-17 15:54:09 UTC 
Current workaroung is to use USE=ghcmakebinary.

The trouble is our gentoo's libffi patch, which works only on
registerised bings with native codegen. Sorry.
Comment 5 Sergei Trofimovich (RETIRED) gentoo-dev 2014-02-15 10:48:24 UTC 
I hope to get proper fix upstream around 7.8.1 as a part of

    https://ghc.haskell.org/trac/ghc/ticket/8748

We can even get ghci working on ppc64 (current state on ghc-7.8.1_rc1 in ::gentoo-haskell overlay).
Comment 6 Sergei Trofimovich (RETIRED) gentoo-dev 2014-06-27 10:04:58 UTC 
Fixed upstream. Will be fine for ghc-7.8+.

Available in overlay as:
dev-lang/ghc-7.8.2::gentoo-haskell
