I successfully compiled cedar 5.1.0 under macOS sierra 10.12 but it won't run, just giving this output:
dyld: Library not loaded: /usr/local/opt/libtiff/lib/libtiff.5.dylib Referenced from: /path/to/cedar5.1.0-mac/build/../bin/cedar Reason: Incompatible library version: cedar requires version 8.0.0 or later, but libtiff.5.dylib provides version 6.0.0 Abort trap: 6
I've installed all dependencies via
homebrew, in particular libtiff is installed (neither version 6.0.0 nor 8.0.0 but homebrew's current):
> brew info libtiff libtiff: stable 4.0.8 (bottled) TIFF library and utilities
I also tried to compile the newest cedar development version (current development master) but this failed probably due to problems installing QGLViewer under mac (it's not available anymore under Mac and manually installing is ... an adventure) and/or qt4/qt5 problems. I could open another issue for that, if you like.
