Hi Andrew,

I had the same problem with ghc-6.8.1 and solved it by adding C:\ghc \ghc-6.8.1\gcc-lib to my PATH variable in environment variables. A copy of ld.exe is in this directory.

In ghc-6.6.1, ld.exe was in the same place and it was working out of the box for me. I don't understand why it is not found any more with ghc-6.8.1.

It turned out that it was a bug that was introduced in Cabal shortly before the release that went with ghc-6.8.1. We added an extra test to check if ld supports the -x flag. This change inadvertently broke the code that finds ld on windows. I can tell you more of the gory details if you care :-). It's fixed now and will be in the release that goes with ghc 6.8.2. Duncan
