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