Hello,

I am new to Haskell. I have written a small quicksort function in Haskell. I want to profile it for time.

I have GHC 6.10.1 version and I have also installed the extra-libs that it has on the Haskell home page.

I followed the following steps for installing the extra-libs:

$ cd /to/the/library/source
$ runghc Setup.hs configure --enable-library-profiling
$ runghc Setup.hs build
$ runghc Setup.hs install

Following is the quicksort code that I’m using:

quicksort [ ] = [ ]

quicksort (x : xs) = quicksort larger ++ [x ] ++ quicksort smaller

                                                                        where

                                                                                    smaller = [a | a <- xs, a <= x ]

                                                                                    larger = [b | b <- xs, b > x ]

When I compile the code with the following command :

$ ghc --make Project.hs -prof -auto-all
 
Then I tested it with the following command :
 
$ Project +RTS -p
 
It generates the .hi and the .o file but I cannot get the .prof file. 
 
Please let me know if any of the steps is missing or where could I check my profiling info. 

Regards,

Sayali.
