I'm trying to update CEDICT to work with the new Cabal (after many years of neglect). http://github.com/jsnx/cedict/tree/40d426c6d7db65948cef5c357633628a5275d877 Right now, it can't seem to find the data header `c/data.h` no matter what I put in the Cabal file. I'd think these lines would do the job: includes : c/data.h c-sources : c/data.c extra-lib-dirs : c include-dirs : c The message I get is: Resolving dependencies... Found existing header file at c/data.h Configuring cedict-0.2.6... setup: Missing dependency on a foreign library: * Missing header file: c/data.h This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. It takes like a minute to err out, too. This isn't urgent or anything but it would be nice to know how to get this build process -- C generation followed by compilation -- to work again. -- Jason Dusek
