Take a patch from meta-riscv, which was submitted upstream by Khem Raj to fix a build issue on RISC-V 32-bit musl configurations. This issue has been discussed with musl developers who believe this is a Busybox issue. The patch from Khem works around the issue by making it a runtime failure just affecting hwclock on RISC-V 32-bit musl instead of a build failure. The correct fix is not really clear, as there seems to be a disagreement between Busybox people and musl people on what the C library settimeofday() function should do, and that's why Busybox is bypassing settimeofday() on musl by making a direct system call, except this system call doesn't exist on RISC-V 32-bit. In the mean time, this patch fixes the long standing Gitlab CI issue: - tests.toolchain.test_external_bootlin.TestExternalToolchainBootlinRiscv32ilp32dMuslStable https://gitlab.com/buildroot.org/buildroot/-/jobs/8954291684 - tests.toolchain.test_external_bootlin.TestExternalToolchainBootlinRiscv32ilp32dMuslBleedingEdge https://gitlab.com/buildroot.org/buildroot/-/jobs/8954291683 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> 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 OFTC IRC.
