The file ApplicationStartup.cpp properties has file location set to ‘Absolute Path’ and therefore shows up as missing (unless you’re on Jules’ Mac, I guess). I think it should be set ‘Relative to Project’.
Is there any reason that the project is set to compile against the 10.3.9 SDK? (Other than a statically linked libstdc++?) It seems to compile fine with SDK set to ‘Current’. Is there something in the README about this requirement? I didn’t find it.
