DESTDIR comes from GNU Automake, I believe. Basically, it's a Makefile variable that is prepended to all installation paths--i.e., if you're installing /usr/bin/epic, you'd use something like "$(DESTDIR)/usr/bin/epic" as the installation path, and have DESTDIR set to an empty string near the top of Makefile. DESTDIR is not set by configure, nor should anything other than the installation rules in Makefile care about it; typical usage is "make install DESTDIR=/tmp/install" As for why you might want DESTDIR--RPMs generally want the files to be installed in a staging area which contains *only* the files from the package, but with paths corresponding to where the files should actually go--i.e., if your staging area is /tmp/install, you want /usr/bin/epic to show up in /tmp/install/usr/bin/epic. DESTDIR obviously makes this very easy to do. -- Kevin L. Mitchell <klmi...@mit.edu>
