Rick Felker suggested[1] this hack as a workaround to musl libc conflict with kernel headers: The problem is linux/libc-compat.h, which should fix this, only works on glibc, by design. See: #ifndef _LIBC_COMPAT_H #define _LIBC_COMPAT_H /* We have included glibc headers... */ #if defined(__GLIBC__) /* Coordinate with glibc netinet/in.h header. */ #if defined(_NETINET_IN_H) If you patch it like this: -#if defined(__GLIBC__) +#if 1 then it should mostly work but it's still all a big hack. I think that's what distros are doing. The problem is that the same header is trying to do two different things: 1. Provide extra linux-kernel-API stuff that's not in the libc/userspace headers. 2. Provide definitions of the standard types and constants for uClibc and klibc, which don't have complete libc headers and rely on the kernel headers for definitions. These two uses really should be separated out into separate headers so that the latter only get included explicitly by uClibc and klibc and otherwise remain completely unused. But that would require coordinated changes/upgrades which are unlikely to happen. :( Upstream musl still evaluates[2][3] a permanent solution. With this in place we can revert (at least) commits |

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
