#4022: GHC Bindist is Broken on FreeBSD/amd64
---------------------------------+------------------------------------------
Reporter: pgj | Owner: pgj
Type: bug | Status: new
Priority: normal | Component: libraries (other)
Version: 6.13 | Keywords: GMP,integer-gmp, x86_64,
FreeBSD, sharedlibs
Os: FreeBSD | Testcase:
Architecture: Unknown/Multiple | Failure: Building GHC failed
Patch: 0 |
---------------------------------+------------------------------------------
After correcting the name of the FreeBSD/amd64 platform in
`PlatformSupportsSharedLibs` it turned out that shared libraries do not
build on that platform at all. Log shows that the problem is with the
integer-gmp library where the sources are not compiled with the `-fPIC`
flag.
Excerpt from the build log:

According to Simon Marlow, it looks like it is building the in-tree gmp
library rather than using a local one, and perhaps there is no shared
version, so `gcc` picks up the static one and complains. There should be a
shared gmp library when shared Haskell libraries are being built.
