While musl and glibc provide the ucontext structure definition on all architectures they support, it is not the case of uClibc. We have been excluding more and more architectures over time, but this isn't really nice as we continuously need to add more. Latest example: the fact that ucontext on ARM is only available on ARM platforms that support the ARM instruction set (i.e not on the Thumb-2 only Cortex-M platforms). Therefore, we introduce a BR2_PACKAGE_LIBSIGSEGV_ARCH_SUPPORTS variable, which: - is set to 'y' for musl and glibc - is set to 'y' for uClibc for the only architectures that are known to provide ucontext (those are the ones that select ARCH_HAS_UCONTEXT in uClibc. Note that we remove the comment, as it would become a way too complicated comment, and we usually don't add comment for such complicated situations (see libunwind for a similar example).

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
