Nice work! Two minor suggestions, apart from the the paths issue already discussed here: * Either include a license file in the source distribution or remove the corresponding line in the .cabal file. Cabal won't work if it is specified and missing. * List all your build dependencies directly, so users can simply do a "cabal install", pulling all missing dependencies automatically. No need for Makefiles or a long description in the README anymore... Patch for those items attached. As a side note, I get a very bad feeling when Hipmunk gets compiled on my x86_64 box: chipmunk/cpCollision.c: In function ‘findVerts’: chipmunk/cpCollision.c:174:0: warning: cast from pointer to integer of different size chipmunk/cpCollision.c:180:0: warning: cast from pointer to integer of different size chipmunk/cpCollision.c: In function ‘findPointsBehindSeg’: chipmunk/cpCollision.c:233:0: warning: cast from pointer to integer of different size chipmunk/cpCollision.c: In function ‘seg2poly’: chipmunk/cpCollision.c:274:0: warning: cast from pointer to integer of different size chipmunk/cpCollision.c:276:0: warning: cast from pointer to integer of different size chipmunk/cpSpace.c: In function ‘queryFunc’: chipmunk/cpSpace.c:411:0: warning: cast from pointer to integer of different size chipmunk/cpSpace.c:411:0: warning: cast from pointer to integer of different size This can't be correct, but I'll probably have to take a look at that. Or is it a know bug that Hipmunk ist not 64bit-clean? Cheers, S.
