Disclaimer

OSX builds have "best effort" support, i.e. build might not work at all, some tests may fail and some sub-projects are excluded from build.

This manual outlines OSX specific setup. For general building and testing instructions see "README" and "Building and Testing changes".

Homebrew is a popular package manager. JPEG XL library and binaries could be installed using it:

brew install jpeg-xl

Dependencies

Make sure that brew doctor does not report serious problems and up-to-date version of XCode is installed.

Installing (actually, building) clang might take a couple hours.

brew install llvm
brew install coreutils cmake giflib jpeg-turbo libpng ninja zlib

Before building the project check that which clang is /usr/local/opt/llvm/bin/clang, not the one provided by XCode. If not, update PATH environment variable.

Also, setting CMAKE_PREFIX_PATH might be necessary for correct include paths resolving, e.g.:

export CMAKE_PREFIX_PATH=`brew --prefix giflib`:`brew --prefix jpeg-turbo`:`brew --prefix libpng`:`brew --prefix zlib`
