Why aren't you using the specific options for profiling?

$ cabal configure --help | grep profiling  -p --enable-library-profiling     Enable Library profiling    --disable-library-profiling    Disable Library profiling    --enable-executable-profiling  Enable Executable profiling    --disable-executable-profiling Disable Executable profiling

This gives the following error: $ cabal configure --enable-executable-profiling ... $ cabal build ... cannot find normal object file `' while linking an interpreted expression However when I apply the same trick as before, first building normally then building with profiling enabled, it works: $ cabal configure ... $ cabal build ... $ cabal configure --enable-executable-profiling ... $ cabal build ... success! Thanks for the hint! Bas
