I don't think Cabal currently has support for installing .h files, I guess that's something we need to look into (Isaac?).

Sounds like it.

How would this look? Let's say that include-dirs=./includes or something relative to the top of the source tree while building. This is so that ghc can find the "includes" while building.

include-dirs gets put into ghc's package.conf file, correct? But then will the installed package need an absolute path for include-dirs? Or can it be relative to ghc's library directory or the package root? If the later, it sounds like no big deal, just create the directory and put anything from the "includes" field into it while installing.

Hmm. Maybe I lost you, but didn't you mean the "include-dirs" field? I'd say that you should recursively find .h files in the directories specified, and copy them.

But then sometimes the include dirs might be an absolute path, maybe? To indicate a .h file that this package is build-depending on? In which case, we might assume that the include files in there are not a part of the package, so we don't try to install them, but they are a dependency and they should be installed on the target system already.

That makes sense. Or, you could have separate include-dirs-nocopy or something. -- John
