Start with install.sh and the fairseq/clib/libbase/balanced_assignment.cpp build step, then inspect the reported Python, PyTorch, pip, and GCC versions in the environment. Compare the installation requirements with the no-sudo setup described in the issue; done means the installation path completes without the compiler failure.
