On my Mac High Sierra 13.6 SVN1424 downloaded, configured, built. One issue as mentioned by Louis Chretian.
BUT If I make a standard Xcode C++ project and simply add only files main.hh and main.cc <http://main.cc/>, then compile I get 24 Value Conversion Issues all of the type Implicit conversion loses integer precision: So is this information deliberately not shown in Make? With some compiler -WnoXXX? Tracked down some of them just for fun and edited the source code to eliminate them. Fixing them all would probably be unproductive donkey work. respect Peter
