Building M2 from source on macOS

Using CMake

If Macaulay2 is bottled on Homebrew for your platform, you can reduce the compilation time by installing dependencies from Homebrew when compiling Macaulay2 from source.

brew tap Macaulay2/tap
brew trust Macaulay2/tap
brew install ccache $(brew deps --1 --include-build macaulay2/tap/M2)

OPT_PREFIX=$(brew deps --1 --include-build macaulay2/tap/M2 | \
	cut -d'/' -f3 | sed "s|^|$HOMEBREW_PREFIX/opt/|" | paste -sd';' -)

Then, from the top directory of the git repository, run:

cd M2/BUILD/build
cmake -GNinja -S ../.. -B . \
      -DBUILD_NATIVE=OFF \
      -DCMAKE_PREFIX_PATH=$OPT_PREFIX \
      -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_INSTALL_PREFIX=/usr

ninja M2-core

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
CC=/usr/bin/gcc CXX=/usr/bin/g++ ../../configure \
    --enable-download \
    --enable-build-libraries="readline"

gmake IgnoreExampleErrors=false
