If you are seeing errors like this during the build process in macOS 10.14 (Mojave):
ld: library not found for -lstdc++ clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command 'g++' failed with exit status 1
try the solution suggested here
In summary, you might need to install the macOS developer SDK header
files separately in Mojave. Open the file
and follow the usual installer instructions.
Then try to build wobble again.
