Read the link I sent, which says "DESTDIR should be supported only in the install* and uninstall* targets, as those are the only targets where it is useful." You use DESTDIR with "make install" as in the example on that page. > If the former is the case, then I would simply copy > /transfer/gcc-build-archive to the target machines and run make install on > each, right? No. You do not run make on the target machines. # configure gcc make make install DESTDIR=/tmp/stage "If your installation step would normally install ‘/usr/local/bin/foo’ and ‘/usr/local/lib/libfoo.a’, then an installation invoked as in the example above would install ‘/tmp/stage/usr/local/bin/foo’ and ‘/tmp/stage/usr/local/lib/libfoo.a’ instead." So then you package up all the files under /tmp/stage, which are arranged in a directory hierarchy exactly as you want in their final installed location, but under /tmp/stage not /, so you just package that directory tree up and then extract it on the target machine cd /tmp/stage tar czf /tmp/gcc.tar.gz . # copy archive to target machine and extract > Also, do I have to install texinfo and ncurses on the target machines? No, because all you do on the target machine is extract an archive.
