Providing kernel headers
Prev Bering-uClibc 7.x - Developer Guide Next

Building the kernel headers tarball is different from building all other Packages.

The kernel headers are a requirement to build the toolchain. The command ./buildtool.pl headers linux builds those headers in the directory headers in the buildtool root directory and creates a link in repo/tolchain/linux-headers.

As we are moving away from the tarball code containers to a true git environment creating these tarballs has become obsolete.

Please note, that toolchains can support different kernel versions, which may be useful especially in transitions to a newer versions, where not all toolchains will be supported immediately. It is advised to keep the kernel headers for the oldest kernel a toolchain uses.
