10 # We package libffi as Haskell package for two reasons:
12 # 1) GHC uses different names for shared and static libs, so it can
13 # choose the lib variant to link with on its own. With regular
14 # libtool styled shared lib names, the linker would interfer and
15 # link against the shared lib variant even when GHC runs in -static
17 # 2) The first issue isn't a problem when a shared lib of libffi would
18 # be installed in system locations, but we do not assume that. So,
19 # when running in -dynamic mode, we must either install libffi to
20 # system locations ourselves, or we must add its location to
21 # respective environment variable, (DY)LD_LIBRARY_PATH etc...before
22 # we call dynamically linked binaries. Especially, the latter is
23 # necessary as GHC calls binary it produced before its installation
24 # phase. However, both mechanism, installing to system locations or
25 # modifying (DY)LD_LIBRARY_PATH, are already in place for Haskell
26 # packages so with packaging libffi as Haskell package we reuse
