The riscv64 build of libsigsegv using musl fails due to a missing definition for REG_SP. This constant is used to index the __gregs array in the ucontext_t structure. This fix moves the musl defintion of REG_SP (and others) from arch/riscv64/bits/reg.h to arch/riscv64/bits/signal.h so that it is picked up correctly. The patch was downloaded from upstream: https://git.musl-libc.org/cgit/musl/commit/?id=329e79299daaa994b8e75941331a1093051ea5d9 Fixes: http://autobuild.buildroot.org/results/8fcd5cb912e513ac08a81e3ee726e29ac22212bb/ Signed-off-by: Mark Corbin <mark@dibsco.co.uk> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
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.
