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