Simon, this is not a build issue, it breaks on all platforms in clang (tested on macOS and Debian+clang-11). There are tons of warnings in the C++ code (way over 1000 lines!) which lead to an error at link time (most of them are type mismatches leading to overrides of virtual methods). The particular one you see:
$ for i in `ls *.o`; do nm $i | sed "s:^:$i:" | grep __ZT.13ParStudentInd; done ParStudentInd.o0000000000001820 S __ZTI13ParStudentInd ParStudentInd.o0000000000001b50 S __ZTS13ParStudentInd ParStudentInd.o00000000000017a0 S __ZTV13ParStudentInd mcmc_student.o U __ZTT13ParStudentInd So mcmc_student expects a VTT, but there is none defined in the implementation (ParStudentInd). To make it clear pass it thought de-mangler like llvm-cxxfilt: ParStudentInd.o: 0000000000001820 S typeinfo for ParStudentInd ParStudentInd.o: 0000000000001b50 S typeinfo name for ParStudentInd ParStudentInd.o: 00000000000017a0 S vtable for ParStudentInd mcmc_student.o: U VTT for ParStudentInd The above is just one of many link errors (pretty much all classes are mismatched in the mcmc_*.cpp files).
