I filed a bug report for a compile error in the latest GHC build, but nobody
has responded to it for 4 days. I might as well try to fix it myself, but I'm
just a functional programming and Haskell beginner.
Here's the bug I filed:
http://hackage.haskell.org/trac/ghc/ticket/715
Here's what the output of GHC says:
------------------------------------------------------------------------
==fptools== make all -wr -f Makefile;
in /home/ayqazi/src/packages/ghc/ghc-build/libraries/OpenAL
------------------------------------------------------------------------

Sound/OpenAL/ALC/Capture.hs:85:3:
Couldn't match expected type `NumSamples'
against inferred type `Sound.OpenAL.Config.ALCint'
Expected type: GettableStateVar NumSamples
Inferred type: GettableStateVar Sound.OpenAL.Config.ALCint
In the expression:
makeGettableStateVar $ (getInteger (Just device) CaptureSamples)
In the definition of `captureNumSamples':
captureNumSamples device
= makeGettableStateVar $ (getInteger (Just
device) CaptureSamples)
make[2]: *** [Sound/OpenAL/ALC/Capture.o] Error 1
make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/ayqazi/src/packages/ghc/ghc-build/libraries'
make: *** [build] Error 1
make: Leaving directory `/home/ayqazi/src/packages/ghc/ghc-build'
Unless you need the OpenAL library, you could try configuring with
--disable-openal as a workaround. I imagine the OpenAL maintainer will
get to this bug in due course.
Cheers,
Simon
