This issue is not only apparent in the binary I am compiling, but also shows up in all the couts and stringstreams in the libraries that I link to it

Unfortunately, it leaves files lying around, as a git status shows a big list of untracked files. How do you tell git "Just bring it back to EXACTLY what was in the last pull, nothing more, nothing less"? 回答1: You have to use git clean -f -d to get rid of untracked files and directories in your working copy. 回答2: If you have files you still want to keep: git clean -di will do an interactive clean which allows you to only
