So it seems the GHCi linker is not using the metadata in the library file correctly? The libpng.dll.a library file clearly contains a reference to libpng3.dll, and I guess since GHC is using the GCC linker, this works fine, but GHCi most likely has its own linker?
If this is correct, we should file a bug report?
This seems to be the same bug: http://hackage.haskell.org/trac/ghc/ticket/1883 The ghci linker is a custom one (AFAIK) and is "different" from GNU ld. That's a feature, not a bug :-) GNU ld, for example, can find either of libxxx.dll or xxx.dll if you say -lxxx. See this ticket for another difference between ghci and GNU ld (ghci's linker tries to link _all_ symbols in the library archive, rather than just the modules that you're using): http://hackage.haskell.org/trac/ghc/ticket/1477 Alistair
