The simplest thing from the cabal pov would be to just include the asm inline into a .c file. > So, two problems.. > > - First, I need to make cabal detect yasm's presence, and call out to > it when appropriate. The former I can do with a configure script; That's the bit that's actually easy within a Setup.hs, no need for non-portable ./configure scripts. > the latter, I'm not quite sure how to do.

You'd have to use the hooks. > - Second, having manually compiled the C/asm bits to .a and .so form, > I did eventually get cabal to link (seemingly) correctly against it, > but it then did not proceed to copy libaes.so into > ~/.cabal/lib/AES/.... I'm not sure how to make it do that, either. I > suppose I'll have to use hooks, but I'd appreciate a little advice on > how, exactly Right, it's only expecting one library. You could either link the stuff into the same lib or add copying code in the copy hook.
