install: To install from the .tgz: opengallery is (almost) ready-to-run out-of-the-box; just un-tar (tar -xzf) the ".tgz" file to some place you have permissions to untar something (maybe your home dir?) and then go to the directory that tar creates and run "make" from there. After that, you're ready to run ogre from that same directory. Alternately, there's an "install-script" to install it to "/usr/local/bin" (by default), or an arbitrary directory (if one is specified on the command line). "make install" works too; it just runs "install-script". The install script is the recommended way of installing it from .tgz, however you must have super-user (root) priviledges to write to "/usr/local/bin". If more than one version of opengallery is installed in a particular dir, then the "ogre" symlink that gets put there in that dir will point to the version that was most recently installed. To install from the .src.rpm: The source rpm, when installed (via "rpm -i") will put the .tgz of the program in /usr/src/redhat/SOURCES, so just follow the instructions above for the .tgz. Need to have permission to write to /usr/src/redhat/SOURCES, which might mean you need to be the super-user (root). To install from an .rpm: Run "rpm -i" on the rpm file of the latest release; or use "rpm --upgrade filename.rpm" (or "rpm -U filename.rpm") if there's an earlier version already installed. Installing with rpm is the easiest way to do it (unless you don't have one of the required packages installed). Need to be root to install from an .rpm. uninstall: If opengallery was installed from the "install-script", use "install-script -u". "install-script -a" will uninstall all opengallery versions from the install directory (/usr/local/bin by default). "make uninstall" will also uninstall it. If it was installed from rpm, use "rpm -e opengallery" (ie, without the version-release numbers nor the .blah.rpm). Probably have to be root to do each.
