haskell - How do I invoke the “--enable-stdcall-fixup” option? -


while building dll under windows following output:

linking main.exe ... warning: resolving _findpeakswrapper linking _findpeakswrapper@16 use --enable-stdcall-fixup disable these warnings creating library file: hsdll.dll.a use --disable-stdcall-fixup disable these fixups

it’s not clear me should placing --enable-stdcall-fixup flag. putting ghc-options field of .cabal file gives ghc error, while putting cc-options or ld-options seems not (the warnings still displayed). should flag go?

googling indicates --enable-stdcall-fixup option ld. there few different pathways cabal's final link step can happen, in case apparently

cabal -> ghc (link step) -> gcc -> ld

so match must specify

ghc-options: -optl-wl,--enable-stdcall-fixup
