Hello,
Recently I was trying to profile some code, and GHC complained that it could not find profiling versions of some 3rd party libraries I was using. According to the GHC manual:
5.2. Compiler options for profiling -prof: To make use of the profiling system all modules must be compiled and linked with the -prof option.
Cabal already supports profiling (from the cabal manual section 3.1.3):
--enable-library-profiling or -p
Request that an additional version of the library with profiling features enabled be built and installed (only for implementations that support profiling).
So, perhaps in addition to the libghc6-*-dev packages, we should be providing libghc6-*-prof packages by default? Or is there some trick that will let me profile my application even if I link against some non-profiling-enabled modules?

I think that providing -prof libraries would be very good. Ian, got an opinion?

Yes providing profiled enabled library as well would be quite usefull. In my HaXml package[1] I already build a normal and a profiled version of the HaXml library.
I don't use Cabal though, but most package do and use dh_haskell and as such it would be nice if dh_haskell would support this as well. It should not be to hard to add this to dh_haskell I think.
Greetings Arjan

Absolutely agreed.
