Hi, 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 ------------------------------------------------------------------------ ../../ghc/compiler/ghc-inplace -H32m -O -W -fno-warn-unused-matches -fwarn-unused-imports -Wall -fffi -Iinclude '-#include "HsOpenAL.h"' -cpp -DCALLCONV=ccall -ignore-package OpenAL -package base -package OpenGL -fgenerics -split-objs -c Sound/OpenAL/ALC/Capture.hs -o Sound/OpenAL/ALC/Capture.o -ohi Sound/OpenAL/ALC/Capture.hi 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' Here is where (I think) the problem lies (I added the line numbers): File Capture.hs: 42: type NumSamples = ALCsizei 83: captureNumSamples :: Device -> GettableStateVar NumSamples 84: captureNumSamples device = 85: makeGettableStateVar $ getInteger (Just device) CaptureSamples ALCsizei is defined in a file Config.hs two directories below this point: 108: -- | Non-negatitve 32-bit binary integer size 109: type ALCsizei = HTYPE_ALCSIZEI A C header file has the entry '#define HTYPE_ALCSIZEI Word32'. Know what's happening? Thanks _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
