Openmoko Linux is an operating system for smartphones developed by the Openmoko project. It is based on the Ångström distribution, comprising various pieces of free software.
The main targets of Openmoko Linux were the Openmoko Neo 1973 and the Neo FreeRunner. Furthermore there were efforts to port the system to other mobile phones.
Openmoko Linux was developed from 2007 to 2009 by Openmoko Inc. The development was discontinued because of financial problems. Afterwards the development of software for the Openmoko phones was taken over by the community and continued in various projects, including SHR, QtMoko and Hackable:1.
Openmoko Linux uses the Linux kernel, GNU libc, the X.Org Server plus their own graphical user environment built using the EFL toolkit, GTK+ toolkit, Qt toolkit and the illume window manager (previously Matchbox window manager). The OpenEmbedded build framework and opkg package management system, are used to create and maintain software packages.
