L.S., I downloaded OpenAL from Hackage and tried to compile a program that uses it (on a Windows XP computer). I got a long list of messages in the linking phase; I found a related ticket, http://hackage.haskell.org/trac/ghc/ticket/1140 with a patch. I applied the patch manually and removed the package and installed it again. The problem remained. The output from the compiler run: ghc -Wall --make TestOpenAL.hs -i"C:\Programs\Haskell\Libs" -dcore-lint -o TestO penAL.exe [1 of 1] Compiling Main ( TestOpenAL.hs, TestOpenAL.o ) TestOpenAL.hs:57:8: Warning: This binding for `s' shadows an existing binding In a pattern binding in a 'do' expression Linking TestOpenAL.exe ...

Then I downloaded OpenAL with the command: darcs get http://darcs.haskell.org/packages/OpenAL/ Trying to install this gives: Libs\OpenAL>runhaskell Setup.hs configure Configuring OpenAL-1.3.1.1... Libs\OpenAL>runhaskell Setup.hs build Preprocessing library OpenAL-1.3.1.1... Building OpenAL-1.3.1.1... Sound/OpenAL/Config.hs:40:0: HsOpenALConfig.h: No such file or directory My questions are: 1) How do I get a proper package installed? 2) How do I find tickets for a certain package? 3) Is there an automatic way of applying patches from the tickets? 4) Is the darcs repository version incomplete? -- Met vriendelijke groet, Henk-Jan van Tuyl -- http://functor.bamikanarie.com http://Van.Tuyl.eu/ --
