FatELF: Universal Binaries For Linux
FatELF is an ELF binary-format extension which adds Fat binary capabilities. It is aimed for Linux and other Unix-like operating systems. Additionally to the CPU architecture abstraction (byte order, word size, CPU instruction set etc.), there is the potential advantage of software-platform abstraction e.g. binaries which support multiple kernel ABIs versions. A proof-of-concept Ubuntu 9.04 image (VM image of Ubuntu 9.04 with Fat Binary support) and development tools are available. As of 2011, support for FatELF is not integrated in the kernel mainline.

Famous quotes containing the word universal:
“Necessity does everything well. In our condition of universal dependence, it seems heroic to let the petitioner be the judge of his necessity, and to give all that is asked, though at great inconvenience.”
—Ralph Waldo Emerson (1803–1882)
