Introduction
Bering-uClibc 5.x - Developer Guide Next


This Developer Guide describes the recommended approach for people who want to:

  • Build Bering-uClibc 5.x from source code.
  • Modify an existing Package.
  • Add a new Package.


All LEAF variants are designed to run on small, embedded systems which do not provide a suitable platform for software development. The distribution therefore needs to be prepared on a separate "build" system and installed onto the "target" system. The build system needs to run Linux but it can be any modern distribution which includes the pre-requisites described on the next page.

One major enhancement from Bering-uClibc 4.x is that the build environment can have a different architecture than target environment, because true cross-compilation is used.


For Bering-uClibc 5.x there is a well-developed toolchain which consists of:

  • A utility called buildtool.pl which automates the process of compiling source code for Packages.
    • This also supports the compilation of the build environment itself, via a special pseudo-package called toolchain.
  • A utility called buildpacket.pl which automates the process of assembling an installable Package (.lrp) file from compiled code.
  • A utility called buildimage.pl which automates the process of preparing a disk Image from a full set of Package files.
