I am trying to install llvm-0.9.0.1 on Windows (through cygwin), on top of a clean install of Haskell Platform 2010.2.0.0.

I do cabal install llvm --configure-option --with-llvm-prefix="C:\\llvm" (which is where I unpacked llvm-gcc4.2-2.8-x86-mingw43.tar.bz2). This fails with

.....mingw\bin\ld.exe: cannot find -lLLVMXCoreAsmPrinter (which is indeed the first -l option on the gcc line).

Does the LLVMXCoreAsmPrinter library exist on your machine? If not, then certainly building LLVM went wrong. If it exists then my next question would be, whether this is a particular problem with LLVMXCoreAsmPrinter or whether this is just the first library GHC tried to bind to. I could suggest to try to build the current state of the package from http://code.haskell.org/llvm/ but I suspect that the building problem would be the same.

[I also tried the llvm-ht package, same issue; I can't tell which of the 2 packages is 'best' from the online doc]

llvm-ht was a little modification by me. In the meantime I could incorporate my changes to the main llvm package. I may flag llvm-ht as deprecated. Btw. there is also the haskell-llvm mailing list. http://projects.haskell.org/cgi-bin/mailman/listinfo/haskell-llvm
