It's nothing to do with not using clang++ or the wrong stdlib, as I
could have told you at the very beginning if you had shown the actual
compile command and error message.
Those symbols appear to be somthing that should be provided by the code
being built. Bottom line is, the code is trying to use some functions or
global variables that are not defined anywhere. Figuring out why would
involve digging into the code.
