Hello @miconda Just as a comment, I thought about this, too, but in the end decided against it because the python3(.x)-config scripts don't send out error messages to stderr. exit_with_usage() echoes to stdout. So if there is an error message it'll be saved inside "tmp_py3_libs". Kind regards, Seb -- You are receiving this because you are subscribed to this thread.
