When trying to use Cabal (e.g. running `runghc Setup.lhs' for HSQL or running `ghci -package Cabal') on Windows 98, I get an error like the following: C:/GHC/GHC-6.4.1/HSCabal.o: unknown symbol `_SHGetFolderPathA' This happens with GHC 6.4 and ghc-6.4.1.20050803-i386-unknown-mingw32.tar.gz. I believe that the problem is that the SHGetFolderPath function is not included in SHELL32.DLL in Windows 98. If the appropriate updates are installed (new IE, I think) then it is available in SHFOLDER.DLL. It is also available in SHFOLDER.DLL in later versions of Windows. I also believe, but haven't been able to verify, that #includeing before using SHGetFolderPath will fix it. I guess changing something in libraries/Cabal/Distribution/Simple/Configure.hs will do the trick, but I don't know much about the FFI. Cheers, Toby.
