Building M2 from source on macOS

Using CMake

You can reduce the compilation time by installing dependencies from Homebrew when compiling Macaulay2 from source. From the top directory of the git repository, run:

brew tap macaulay2/tap
brew install ccache
brew install $(brew deps --1 --include-build macaulay2/tap/M2)

deps=$(brew deps --1 --include-optional macaulay2/tap/M2 | tr '\n' ';')
paths=$HOMEBREW_PREFIX/opt/${deps//;/;$HOMEBREW_PREFIX/opt/}

cd M2/BUILD/build
git clone https://github.com/Macaulay2/M2.git
cmake -GNinja -S ../.. -B . \
      -DBUILD_NATIVE=OFF \
      -DCMAKE_PREFIX_PATH=$paths \
      -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_INSTALL_PREFIX=/usr

Using Autotools

From the top directory of the git repository, run:

brew install ccache ctags gnu-tar make wget yasm

cd M2
gmake get-libtool
gmake -f Makefile

cd BUILD/build
../../configure --enable-download --enable-build-libraries="readline" CC=/usr/bin/gcc CXX=/usr/bin/g++
gmake IgnoreExampleErrors=false
