2024.02 Bootlin toolchains have been released, so let's update the support in Buildroot. Notable changes: - Bleeding edge toolchains now use binutils 2.42, and stable toolchains use binutils 2.41. This fixes binutils bug 27597 for both. - glibc has been updated to 2.39 - musl has been updated to 1.2.5, which brings 32-bit RISC-V support. Due to this, 2 new toolchain variants are added: 32-bit RISC-V stable, 32-bit RISC-V bleeding edge. - Bleeding edge toolchains now use 5.15 kernel headers, and stable toolchains now use 4.19 kernel headers - Fortran support has been disabled on Microblaze, as the libgfortran build at -O2 causes an internal compiler error. All runtime tests are passing, except the ones for the new RISC-V 32-bit musl toolchain, for which Busybox fails to build due to an interaction between musl-specific code in Busybox and musl. This issue has been reported: https://www.openwall.com/lists/musl/2024/03/03/2 The runtime tests are nevertheless included, with the hope that this issue will reasonably quickly be resolved.

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.
