Fixes build errors seen with Gitlab pipeline and this defconfig: support/config-fragments/autobuild/bootlin-aarch64-glibc-old.config https://gitlab.com/bkuhls/buildroot/-/jobs/14570080455 aarch64-linux-gcc.br_real: error: unrecognized command line option ‘-Wimplicit-fallthrough=5’; did you mean ‘-Wno-fallthrough’? aarch64-linux-gcc.br_real: error: unrecognized command line option ‘-Wshadow=local’; did you mean ‘-Wshadow-ivar’? Removing all the unrecognized command line options from CMakeLists.txt showed more build errors during compile: output/build/odhcp6c-24485bb4b35ab84c17c2e87bd561d026d4c15c00/src/odhcp6c.h:47:46: error: expected ‘)’ before ‘__VA_OPT__’ #define error(fmt, ...) __iflog(LOG_ERR, fmt __VA_OPT__(, ) __VA_ARGS__) Another pipeline with gcc 9 showed other errors: https://gitlab.com/bkuhls/buildroot/-/jobs/14570080479 /builds/bkuhls/buildroot/br-test-pkg/br-arm-basic/build/odhcp6c-24485bb4b35ab84c17c2e87bd561d026d4c15c00/src/dhcpv6.c:1126:4: error: a label can only be part of a statement and a declaration is not a statement 1126 | struct dhcpv6_auth *r = (void*)&odata[-DHCPV6_OPT_HDR_SIZE]; so we raise the minimum gcc version to 10.

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