Requirement

• 20GB+ of disk size.
  • Using highspeed disk(e.g. SSD or NVMe) preferred.
• ninja-build
• cmake
• C/C++ compiler
• llvm-mingw cross compiler
  • https://github.com/mstorsjo/llvm-mingw : 20200325(LLVM 10.0) or newer

Setup

Clone llvm-project repo.

$ ./clone-repo.sh

Ubuntu 18.04(x86-64) build

Requirements

• llvm-mingw cross compiler toolchain(llvm-mingw-20200325-ubuntu-18.04.tar.xz)

Set path to llvm-mingw in environment variable See github actions workflow file for details.

Build native llvm/clang tools

First we need to build native tools(e.g. clang-tblgen) on host.

$ ./build-native-tools.sh

Build libclang, libllvm for Windows target.

Edit path to llvm-mignw in build-llvm-mingw-cross.sh, then

$ ./build-llvm-mingw-cross.sh

Build libcxx, libcxxabi, compiler-rt

Edit path to llvm-mignw in build-libcxx-mingw-cross.sh, then

$ ./build-libcxx-mingw-cross.sh

Build compiler-rt

You can build compiler-rt solely(no dependency with libclang, libllvm, etc). Only you need is llvm-mingw clang compiler.

Edit path to llvm-mignw in build-compiler-rt-mingw-cross.sh, then

$ ./build-compiler-rt-mingw-cross.sh

TODO

• Create artiface and release using git tag.
