First, let me say that I surfed for a few hours both to find the right, recent binary install instructions and looking for feedback on the problem I encountered. Here is briefly what I came up with and my one problem. (1) Installed MinGW and MSYS using the latest new installer. Set path, modified fstab, etc. No problems. (2) Downloaded the three LLVM binaries archive files: clang-2.9-mingw32-i386.tar.bz2 llvm-2.9-mingw32-i386.tar.bz2 llvm-gcc4.2-2.9-x86-mingw32.tar.bz2 (3) Uncompressed the binaries using the MinGW directory as the "root" directory. (4) This worked just fine for the first two archives, with the no file name conflicts, the clang and llvm utility binaries ending up in MingGW\bin and so on. clang-2.9-mingw32-i386.tar.bz2 llvm-2.9-mingw32-i386.tar.bz2 (5) With the last binary archive, I got file name conflicts contrary to the Windows binary install docs (I just canceled the decompression of that archive: llvm-gcc4.2-2.9-x86-mingw32.tar.bz2 (6) Clang's gcc works just fine from the MSYS bash command line. I presume the utility suite will as well. (7) Can anyone shed light on the troublesome llvm-gcc4.2 archive? Do I need it, or can I just use Clang and the LLVM utilities? Or does it contain other essential LLVM system components, headers, libraries, etc. I might need? Does anyone know if the file name conflicts installing per instructions in the MingGW directory is a problem or just an inadvertent exact duplicate file(s) stored in multiple archives (either from MinGW or from the other two LLVM binary archives that installed without incident)? Mucho thanks in advance! - Scott
