This patch modifies the formula to build both _release_ and _debug_ versions simultaneously. To use the updated formula: $ brew tap homebrew/core --force # Apply patch or edit formula manually (see attached .patch) $ brew --repository homebrew/core $ patch -d /opt/homebrew/Library/Taps/homebrew/homebrew-core/ < ./libmps-debug.patch # edit formula manually $ brew edit --print-path libmps # Compile from latest source with debug symbols $ HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source libmps --HEAD --
