The Linux kernel offers a nice and easy-to-use infra to build out-of-tree kernel modules. Currently, we have quite a few packages that build kernel modules, and most duplicate (or rewrite) the same code over-and-over again. Introduce a new infrastructure that provides helpers to build kernel modules, so packages do not have to duplicate/rewrite that. The infrastructure, unlike any other package infra, is not standalone. It needs another package infra to be used. This is so that packages that provide both userland and kernel modules can be built easily. So, this infra only defines post-build and post-install hooks, that will build the kernel modules after the rest of the package. We need to override PWD, because some packages will use it to find their own includes (and other helper files). PWD is inherited from the environment, so it gets whatever value it had when make was launched, which happens to be Buildroot's own top source tree. So, we just force PWD to the proper value, rather than cd-ing first. Also, no host version is provided, since it does not make sense to build kernel modules for the host. Signed-off-by: "Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
