Hi Ivan, I tried doing

cabal install "parsec >= 3" --reinstall --enable-library-profiling This complained about bytestring ... so I did this - cabal install "bytestring" --reinstall --enable-library-profiling And this complained about base - Data/ByteString.hs:278:7: Could not find module `GHC.ST': Perhaps you haven't installed the profiling libraries for package `base'? Use -v to see a list of the files searched for. cabal: Error: some packages failed to install: bytestring-0.9.1.5 failed during the building phase. The exception was: exit: ExitFailure 1 [kashyap@trinity318 ~]$ cabal install "base" --reinstall --enable-library-profiling Resolving dependencies... cabal: internal error: impossible

Am I missing something? On Tue, Apr 20, 2010 at 6:59 PM, Ivan Lazar Miljenovic < ivan.miljenovic@gmail.com> wrote:

How did you install parsec? You need to rebuild it with profiling library support. If you used cabal-install, you have two options:

1) set library-profiling to True in ~/.cabal/config and then cabal install parsec --reinstall 2) cabal install parsec --reinstall --enable-library-profiling

...

When I build the project without the "-prof -auto-all", the project compiles without any error or warning. I build GHC (6.10.4) from source, without changing any build option.

This has nothing to do with GHC.

Thanks Daniel, that worked. On Tue, Apr 20, 2010 at 11:24 PM, Daniel Fischer wrote:

You cannot reinstall or upgrade core libs (basically, what comes with the compiler). If your GHC came from a system package (and I think the binaries from the GHC page include profiling libs and they're built by default when building GHC from source, so you wouldn't have that problem), you probably don't have installed the package with the profiling libraries, something like

yum/apt-get install libghc??-prof

should get you the profiling libraries for base, bytestring and a few others, then cabal install "parsec >= 3" --reinstall --enable-library-profiling should work. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
