Cabal not installing dependencies when needing profiling libraries?

Question

I want to compile my program with profiling, so I run:

$ cabal configure --enable-executable-profiling
...
$ cabal build
...
    Could not find module \'Grap         


        

Answer 1

I've enabled library-profiling: True in my ~/.cabal/config file. From then on, any new installations will automatically enable profiling.

Unfortunately that still means I had to manually reinstall for the old packages already installed. Although, after a while of doing this manually, I now have most packages reinstalled with profiling enabled...
