The MacOS build on the page is quite old, and doesn't reflect recent fixes/enhancements. If you want to build it from source for MacOS the included instructions won't work because Simon's 'halibut' documentation tool will be missing. So you need to: 1) Build Halibut from source: git clone https://git.tartarus.org/simon/halibut.git cd halibut cmake -B build -DCMAKE_BUILD_TYPE=Release cmake --build build -j # binary lands at: halibut/build/halibut 2) Build the puzzles app, pointing CMake at that halibut binary. Do this in a fresh build dir (don't reuse a stale top-level CMakeCache.txt that already recorded HALIBUT-NOTFOUND): cd /path/to/puzzles cmake -B build-osx -DCMAKE_BUILD_TYPE=Release \ -DHALIBUT=/full/path/to/halibut/build/halibut cmake --build build-osx -j 3) Now you have build-osx/Puzzles.app and can (optionally) build the dmg: cd build-osx && cpack
