Hugin Compiling Fedora
The hugin and enblend stable releases are part of default fedora, available via the Add/Remove Software menu. Note that there is no autopano-sift in fedora due to patent issues, but autopano-sift-C can be found in the livna 3rd party package repository.
Otherwise, recent-ish hugin snapshots and other panorama-related software can usually be found at the fedora panorama repository. To subscribe just follow this panorama release link, use the Package Installer option, and each time you do a Software Update hugin will be upgraded to the latest snapshot.
If you want to compile hugin yourself, just follow the instructions in the INSTALL_cmake file, you will need these development packages (June 2008): libpano13-devel zlib-devel libtiff-devel libjpeg-devel libpng-devel gettext-devel wxGTK-devel boost-devel cmake desktop-file-utils OpenEXR-devel gcc-c++ exiv2-devel
The source RPM package contains an hugin.spec file which is both the build documentation and the script for an automated build (other linux packaging systems work basically the same way).
