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 'Graphics.UI.GLUT':       Perhaps you havent installed the profiling libraries for package 'GLUT-2.2.2.0'? ... $ # indeed I have not installed the prof libs for GLUT, so.. $ cabal install -p GLUT --reinstall ...     Could not find module 'Graphics.Rendering.OpenGL':       Perhaps you havent installed the profiling libraries for package 'OpenGL-2.4.0.1'? ... 

So, the problem is, that unlike cabal's usual welcome behavior, cabal doesn't resolve the dependencies and install them when needing profiling libraries.

I can work around it by resolving the dependencies manually (by following errors that appear after a while of compiling):

$ cabal install -p OpenGLRaw --reinstall $ cabal install -p StateVar --reinstall $ cabal install -p Tensor --reinstall $ cabal install -p ObjectName --reinstall $ cabal install -p GLURaw --reinstall $ cabal install -p OpenGL --reinstall $ cabal install -p GLUT --reinstall 

And then repeat for my next dependency..

Is there a better way to do this? i.e do make cabal do the work on its own as it does for normal libraries?

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...
