Does MissingH's cabal file have a line
Ghc-Prof-Options: -prof -auto-all
No, it doesn't. None of my Cabal files do. Could anyone confirm if this fixes it?
The rhs of the option is added to compiler command line when the --enable-library-profiling option is included to configure. Without this, the --enable-library-profiling switch doesn't do anything. (Arguably a bug that cabal silently does nothing instead of reporting an error.)
I'd argue that Cabal should make this a default. It seems silly to have to add this boilerplate code to every cabal file out there just to have a sensible default.
Actually, for some reason my brain missed that your were talking about a library, not an application. As lemmih said, --enable-executable- profiling will make you a profiling library. If you are building an app however, unless you include a "Ghc-Prof-Options" something like the above, or add cost center annotations yourself, you just get a profile that tells you that Main took 100% of the time. Best, Greg
Thanks for the info.
