I'm trying to upgrade from ghc 6.8.3 to 6.10.1. Unfortunately, there seem to be problems with the Windows version. (I've installed it on two different machines, both Windows XP, and they've both had the same problem. Both worked fine with 6.8.3.) When I run hsc2hs, on an hsc file, I get the error, "Can't find gcc". Just as an experiment, I tried adding c:\ghc\ghc-6.10.1 to my path. That lets it find gcc, but then it can't find cc1. If I go even further down this road and add c:\ghc\ghc-6.10.1\gcc-lib to my path, it can find cc1, but then I get a stream of errors about not being able to find header files, such as HsFFI.h. Does anybody have any clues here to help me? I can provide code, or even access to the machine, if needed. We're also happy to pay for support, if someone out there is offering commercial support for ghc. cjs -- Curt Sampson <cjs@starling-software.com> +81 90 7737 2974 Functional programming in all senses of the word: http://www.starling-software.com
