roll back directory to original after compiling.
 

following some directions on a website i git cloned into a repository and issued the following commands

autogen.sh
make
sudo make install.

since then the git repo went down. i want to be able to use the same software on a re-installation in the future if I cannot find the software on another repo.

What files do i have to delete to be able to run autogen.sh on on another computer, or on the same computer after a fresh install.

Unless you are altering the configure/Makfile stubs, ie configure.ac/Makefile.am and so on you should just need to do a ./configure ... as normal, if the new machine is drastically differerent you can just re-run autogen again, there shouldnt be any need to manually remove files, also to be safe run make distclean on the the new machine before the configure.
