I have a working cygwin llvm and llvm-gcc, but had no time to produce a proper package yet. Attached are my cygport files and my local config. No patches were needed. But I haven't bothered to build clang yet, just the Clang llvmc plugin and llvm-gcc, which I thought is harder to build and gives us more gcc compatibility. > Could it be possible to provide an implementation ? cygwin has only dlsym() not the SGI DL_info + dladdr() yet. clang just needs it to get the path for the CIndex dll. This should be possible with the code in the LLVM_ON_WIN32 section, and convert then the path from win to posix with cygwin_conv_path(). -- Reini Urban http://phpwiki.org/ http://murbreak.at/
