Eventually, I think using cabal during development may be convenient. The only drawback is that you have to specify each dependency and -- above all -- every module each time you add one. Nevertheless, I'm not convinced regarding the use of Makefiles with Cabal. I happen to think it's a bit outsize. A shell script is enough. By the way, I've found another way to develop simultaneously a (or many) library(ies) and an executable. It would be to use a local ghc package database. In my project directory, I do: ghc-pky init pkg.conf.d It create a directory pkg.conf.d which will contain my local database. Then all the libs must be configured with: cabal configure --package-db pkg.conf.d (or 'runhaskell Setup.hs configure --package-db pkg.conf.d' if you don't use cabal-install) Then build normally ('cabal build') Then, the little trouble is that you have to register you newly-built manually with a: cabal register --inplace (Anyone knows how to tell cabal to register automatically to the local pkg database?) Then, to compile you executable with ghc (because Cabal is definitely not convient when you have a lib and an executable in the same package): ghc --make --package-conf pkg.conf.d main.hs Again, should you have better/simpler ways to achieve this, I would be glad to know them.

Another great thread. I'm another who uses both make and cabal. I try to automate a lot of things and find a makefile easier for quick scripting. Perhaps at some point I'll get by with just cabal. Here's an example:

An unusual feature, I think, is the use of the little-known sp tool for auto-recompiling (see "ci" rule). Typically I leave make ci running in an emacs shell window, where I can watch the errors as I edit and save source. I don't have clickable errors currently, I get by with linum-mode. When I need to explore I'll run ghci in another shell window. After reading this thread, I'm going to try using C-c C-l more.
