This is a helpful batch script to automate building the LLVM toolchain on Windows using MSVC or Clang itself!

Usage

NOTE: If you want to build clang with clang itself, use the Ninja generator instead.

1. Open a command prompt (cmd.exe) and change directory to the root of where you want the root of your LLVM directory tree.

    >cd C:\llvm-7.0.0
   

2. Place the build scripts at the root of the LLVM directory tree.

    >git clone https://github.com/ajkhoury/LLVM-Build-Windows .
   

3. See here on how to obtain the LLVM source code for building:

   https://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary

4. Use the -help argument for the script for more information:

    >build-llvm.bat -help
    Detected 64 bit system...
    Usage:
        build-llvm.bat [options]
   
    Options:
        -configure                   Configure the project
        -build                       Build the project
        -static                      Configure and build the project statically
        -debug                       Build project with debug configuration
        -target ARCH                 Set the target architecture
        -directory DIRECTORY         Use specified DIRECTORY for build directory
        -help | --help | -? | /?     Display this help and exit
   

5. Run the build script for the target of your choice:

   x64

    >build-llvm.bat -configure -build -static -target x64 -directory build-release-x64
   

   x86

    >build-llvm.bat -configure -build -static -target x86 -directory build-release-x86
