Oh, hmm, I actually looked at the code and we do already inspect the error string from `dlopen` and try to parse a linker script. The problem is that we don't support `INPUT(-llibrary)`. I guess we can transform the name to `liblibrary.so` in that case?
I think that's what's needed. I don't run Arch Linux right now. Maybe I'll have some time to install it in a VM and try out this approach. When I fixed #2615, the hardest part was generating a test to prove it worked. I envision the same difficulty here.
I still would like to avoid incurring dependencies on `.so`s that are really linker scripts, if possible...
I don't see any way to avoid this unless we find a way to call `ld` as a helper. Doing this would be way beyond my level of understanding. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9237#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
