The version of Cabal that comes with GHC (6.4 and 6.4.1) doesn't run on Windows 98 because of a missing SHGetFolderPathA function, so I thought I'd try to compile version 1.1.1 myself. I see that some work has been done in CVS for this problem, but I thought I'd post the changes I had to make to get 1.1.1 to work incase this is helpful to other people or to getting it fixed propoerly. I'm using MinGW 4.1, MSYS 1.0.10 and MSYS Developer Tool Kit 1.0.1. I've attached a patch against version 1.1.1. First, I tried compiling setup without any changes: $ make HCBASE=/c/ghc/ghc-6.4.1/bin/ setup ... Compiling Main ( Setup.lhs, dist/tmp/Main.o ) Linking ... dist/tmp/Distribution/Simple/Configure.o(.text+0xe41):fake: undefined reference to `SHGetFolderPath@20' make: *** [setup] Error 1 Ok, this seems to be because we need to pick either the A or W version. I'm not sure how to get this to happen automatically, but I guess we want the A version: $ diff ../cabal-1.1.1.orig/Distribution/Simple/Configure.hs Distribution/Simple /Configure.hs 256c256 < foreign import stdcall unsafe "SHGetFolderPath" ---

foreign import stdcall unsafe "SHGetFolderPathA"

Now, I try again: $ make HCBASE=/c/ghc/ghc-6.4.1/bin/ setup ... Skipping Main ( Setup.lhs, dist/tmp/Main.o ) Linking ... Yay, it compiled! Now I try to run it: $ make HCBASE=/c/ghc/ghc-6.4.1/bin/ config "The SETUP.EXE file is linked to missing export SHELL32.DLL:SHGetFolderPathA" (The message is GUI dialog box.) Ah, this is because SHGetFolderPathA is not in SHELL32.DLL on Windows 98, but in SHFOLDER.DLL. It is also in SHFOLDER.DLL on later versions, so this change should be safe: $ diff ../cabal-1.1.1.orig/GNUmakefile GNUmakefile 4c4 < GHCFLAGS= --make -Wall -fno-warn-unused-matches -cpp ---

GHCFLAGS= --make -Wall -fno-warn-unused-matches -cpp -lshfolder

Try again: $ make HCBASE=/c/ghc/ghc-6.4.1/bin/ config ... Skipping Main ( Setup.lhs, dist/tmp/Main.o ) Linking ... ./setup configure --ghc --prefix=/usr/local Configuring Cabal-1.1.1... configure: Using install prefix: C:/MSYS/1.0/local configure: Using compiler: c:\GHC\GHC-6.4.1\BIN\ghc.exe configure: Compiler flavor: GHC configure: Compiler version: 6.4.1 configure: Using package tool: c:\GHC\GHC-6.4.1\BIN\ghc-pkg.exe configure: No haddock found configure: No happy found configure: No alex found configure: Using hsc2hs: c:\GHC\GHC-6.4.1\BIN\hsc2hs.exe configure: No c2hs found configure: No cpphs found configure: No greencard found configure: Dependency base-any: using base-1.0 configure: Dependency util-any: using util-1.0 Yay!

Registering Cabal-1.1.1... Ok, it all seems fine. Now to try to use it: $ cd tests/HSQL $ runghc Setup.lhs configure ghc.exe: unable to load package `Cabal-1.1.1' <interactive>: C:/MSYS/1.0/local\Haskell\Cabal-1.1.1\ghc-6.4.1/HSCabal-1.1.1.o: unknown symbol `_SHGetFolderPathA' Bummer. We need to link with SHFOLDER.DLL. So, we change Cabal's cabal file (similarly to the comment that was in CVS recently): $ cd ../.. $ diff -u ../cabal-1.1.1.orig/Cabal.cabal Cabal.cabal --- ../cabal-1.1.1.orig/Cabal.cabal Sat Aug 6 11:50:00 2005 +++ Cabal.cabal Sat Aug 6 12:17:46 2005 @@ -48,6 +48,7 @@ Distribution.Compat.Exception, Distribution.Compat.RawSystem Extensions: CPP +Extra-Libraries: shfolder executable: cabal-setup main-is: DefaultSetup.lhs Then, install again and try the test again: $ make HCBASE=/c/ghc/ghc-6.4.1/bin/ install ...

Using this version I have successfully installed the real HSQL. How, it seems wrong to have to specify the A or W version explicitly because there is a #define for it that depends on whther UNICODE is defined. I don't know why that's not being picked up (it's in shldobj.h and I see that that's been specified in CVS, but adding it makes no difference for me.) The patch follows:
