After fixing the <bits/local_lim.h> issue by using <limits.h>, the build still fail with udefined __WORDSIZE. Adding <sys/user.h> to define __WORDSIZE reveal that xenomai use <error.h> which is not provided by musl. The discussion on the musl mailing list [1] about glibc error reporting functions concluded to not add this support in the C library. For now, disable Xenomai user space support for musl toolchains since it require several patches to build correctly and needs to remove each glibc error reporting functions. Users interested in musl support for Xenomai can work with upstream to fix these issues and revert this patch.

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.
