Adam Bilbrough (Gibbon)


Adam Bilbrough, commonly known as Gibbon within the Doom community and atsb elsewhere, is a British programmer. Gibbon's work focuses around maintaining 64-bit derivatives of older source ports such as WinMBF and Boom and doing so for several architectures.

Additionally, he is known for compiling several builds of ports that do not have any compiled binaries, again to several platforms such as Microsoft Windows, Linux, ARM based Apple Mac models (such as the Apple M1), and Intel based Apple Mac models.


In regards to Doom history, Bilbrough has created the following source ports:

Source port builds[edit]

In addition to his own custom ports, Bilbrough hosts a service called Source port builds where several source ports, left in a unmaintained or otherwise compile-only state, are compiled into a playable binary for various platforms and maintained. No changes are made except which are required (upstream devs will be notified) and are compiled for Windows (64-bit), for Linux, for FreeBSD and MacOS, both for Intel x86 processors and Apple ARM based silicon. The following ports have been compiled:

Other developments[edit]

Outside of Doom, Bilbrough is a maintainer of several packages for the Debian operating system and the GNU Project. These include the document organizing program OrgaDoc and the job scheduler program Mcron, a fork of the software utility cron.
