• https://github.com/clasp-developers/clasp/wiki/Build-Instructions

MacOS installation of dependencies

While Clasp requires a specific release of llvm and does not use the Xcode version, it does use Xcode files. You will need to first install Homebrew.

1. brew install cmake llvm@6 libffi bdw-gc gmp boost libunwind-headers sbcl
2. git clone https://github.com/clasp-developers/clasp.git
3. If on mojave, after reinstalling xcode execute (from the gui):
   • /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg to get the headers in /usr/include/
4. cd clasp
5. ./waf configure; if ./waf configure fails, see hint in linux instructions.
6. ./waf build_cboehm

The executables will be in clasp/build/boehm/cclasp-boehm and clasp/build/mps/cclasp-mps
