== FatELF: universal binaries for Linux ==
FatELF is an ELF binary-format extension that adds fat binary capabilities.<ref name="fatelfspec">{{cite web|publisher=icculus.org| title=fatelf-specification v1| url=http://hg.icculus.org/icculus/fatelf/raw-file/tip/docs/fatelf-specification.txt| access-date=2010-07-25|last=Gordon| first=Ryan}}</ref> 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 ABI versions. {{as of|2021}}, FatELF has not been integrated into the mainline Linux kernel.<ref name="kernel1">{{cite web|publisher=icculus.org| title=FatELF: Turns out I liked the uncertainty better| url=https://icculus.org/cgi-bin/finger/finger.pl?user=icculus&date=2009-11-03&time=19-08-04|access-date=2010-07-13|last=Gordon|first=Ryan}}</ref><ref name="kernel2">{{cite web|publisher=osnews.com| title=Ryan Gordon Halts FatELF Project| url=https://www.osnews.com/story/22446/ryan-gordon-halts-fatelf-project|date=2009-11-03|access-date=2010-07-05|last=Holwerda|first=Thom}}</ref><ref name=selfanatomy>{{cite web|url=https://lwn.net/Articles/392862/ |title=SELF: Anatomy of an (alleged) failure|publisher= Linux Weekly News|date= June 23, 2010|first=Joe|last=Brockmeier|access-date=2011-02-06}}</ref>
