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

• Build Bering-uClibc 4.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 "host" system and installed onto the "target" system. The host system needs to run Linux but it can be any modern distribution which includes the pre-requisites described on the next page. One enhancement from Bering-uClibc 3.x is that the build environment can be 64-bit and still generate code for a 32-bit target system.

For Bering-uClibc 4.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 buildenv.
• 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.
