Hey,

does anyone know about this? Resending as I got no replies (yet) ;)

Just for the record, I have no idea; I've never really used profiling and couldn't figure out how to make it work in general (at least not in a short amount of time).

Are you sure your problem is restricted to MissingH? I can't think of anything special about it that would throw off profiling.

Does MissingH's cabal file have a line Ghc-Prof-Options: -prof -auto-all ? 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.) Best Wishes, Greg

No, it doesn't. None of my Cabal files do. Could anyone confirm if this fixes it?

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.

Use Cabal to compile and install the profiling libraries. There is a flag called --enable-profiling, or something like that. If you use GHC you will get two libraries, one without profiling, and one with, but that is a technical detail that Cabal takes care of. Just use the flag, and things should work. -- /NAD

Thanks, this works! I had to build all the other libraries that are required with profiling support too. I also wrote it down on the MissingH wiki, see http://software.complete.org/missingh/wiki/Profiling -chris On 12 Jan, 2007, at 4:08 , Spencer Janssen wrote:

The typical way to add profiling support to a Cabal lib is to add - p at configure time (ie "runhaskell Setup.hs configure -p"). Have you tried this?

Hey all,

When compiling without those options, everything works just fine. I built missingh from source, and added -prof -auto-all to GHCPARMS, and did a ./setup configure,make,install and still no result. Does anyone know what could be wrong? I'd really like to keep using MissingH and having profiling support at the same time.

Thanks, -chris
