I'm not the original reporter, but I can confirm that I am able to install Criterion-0.5.0 with ghc-6.12.1 on OSX 10.6. One datum, anyway. The problem isn't with criterion itself, but with vector-algorithms. The vector library relies heavily on type families, which have dodgy support in ghc-6.10.

As a matter of fact, this particular problem is easy to fix by adding a couple of type signatures. I used to run into it frequently back when I was still working with 6.10. I'll send a patch.

I've incorporated the patch and released a bug fix version 0.3.1. -- Dan

Hi, Thanks for the replies .. I upgraded ghc to ghc 6.12 .. and installed Criterion through cabal .. There is another problem here which I really don't know if it is due to the ghc version or the dependencies or my OS version !!! I installed Criterion package,libpng, gnuplot .. and lots of other packages which seemed to be useful ! Unfortunately when I run the below command it gives me errors at the end and says it can’t plot the png output . ./profile -t png:500×175 -k png:500×175 .. .. .. output type PNG 500 175 not supported on this platform output type PNG 500 175 not supported on this platform Why is it so ? What else do I need to be able to actually see the graphical result ? Do I have to install gtk2hs as well ? Actually, I installed gtk2hs-0.10.1, but it seems that it can’t be installed completely on ghc 6.12 !! Below is the error I get after running make and make install : (before, I am not sure if my question is related to this thread or not .. sorry in advance) For example I get this error at the end, after I run make : make: *** [package.conf.inplace] Error 1 make: *** Deleting file `package.conf.inplace' and I get this one at the end, when I run make install : ghc: can’t find a package database at package.conf.inplace make: *** [glib/System/Glib.o] Error 1 Is there any way to get this fixed ? Do I really have to install gtk2hs ? Thanks, On Wed, Apr 14, 2010 at 3:24 PM, Simon Peyton-Jones wrote:

There hasn't been an official release of gtk2hs that supports GHC 6.12.1 yet, and gtk2hs is a nightmare on the Mac anyway. Unfortunately, this means that you get to produce CSV files and generate the charts yourself for now.

Someone sent me a gnuplot patch for criterion, but I haven't reviewed it yet.

Hi Bryan .. Actualy by the term OS , I meant my operating system is ubuntu 9.10 .. still gtk2hs will not work on my machine ? The thing is , I was told that Criterion package will not work on ghc 6.10 and I have to upgrade it to ghc 6.12 .. still it doesn't plot anything as an output .. What I don't understand it that, do I really need this gtk2hs in order to use the Criterion package and get it to work ?? If yes, then why one can't work with ghc 6.12 and one can't work with the older version ? Could you please help me out . Thanks ..
