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-126.96.36.199'? ... $ # 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-188.8.131.52'? ...
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?
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...
