Comments on: Criterion, a new benchmarking library for Haskell http://www.serpentine.com/blog/2009/09/29/criterion-a-new-benchmarking-library-for-haskell/ Bryan O'Sullivan's blog Wed, 08 Feb 2012 06:41:38 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Hartmut http://www.serpentine.com/blog/2009/09/29/criterion-a-new-benchmarking-library-for-haskell/comment-page-1/#comment-311432 Hartmut Tue, 19 Jul 2011 21:18:02 +0000 http://www.serpentine.com/blog/?p=461#comment-311432 If you encounter problems like "ERROR: output type Window 800 600 not supported on this platform", You can try the following (I got it working on my Linux machine with GHC 7.0.2: 1) cabal update && cabal install gtk2hs-buildtools cairo gtk 2) cabal install -fChart -fgtk (or change both flags in the .cabal-file to True if they are defaulted to False) 3) ./Fibber -t win -k win or ./Fibber -t png:450x175 -k png:450x175 Then the images will generate well :-) If you encounter problems like “ERROR: output type Window 800 600 not supported on this platform”, You can try the following (I got it working on my Linux machine with GHC 7.0.2:

1)
cabal update && cabal install gtk2hs-buildtools cairo gtk

2)
cabal install -fChart -fgtk
(or change both flags in the .cabal-file to True if they are defaulted to False)

3)
./Fibber -t win -k win
or
./Fibber -t png:450×175 -k png:450×175

Then the images will generate well :-)

It's purpose is to gather people concerned about the state of experimental computer science and the way in which we benchmark systems, languages, implementations, etc. because things are not as nice as we often like to think.

It has got so many useful info .. I installed Criterion package,libpng .. on ubuntu 9.10 which has got ghc 6.12 . Unfortunately when I run the command it gives me errors and says it can't plot the png output . ./profile -t png:500x175 -k png:500x175 output type PNG 500 175 not supported on this platform output type PNG 500 175 not supported on this platform Why is it so ?

This is just what I was searching for. Installation as usual, one blogpost to understand it and all the nice features one could want. Your library fills a niche for the run-of-the-mill developer.
