While building host-rust with a musl based toolchain without C++ compiler, the build fail since libunwind bundled in rust sources needs a C++ compiler. cargo:warning=i686-buildroot-linux-musl-gcc.br_real: error: [...]/host-rust-1.62.0/src/llvm-project/libunwind/src/Unwind-EHABI.cpp: C++ compiler not installed on this system Note: the issues can't be reproduced with a glibc based toolchain without C++ probaly due to extra steps required to support musl libc. We could add the C++ dependency direclty to host-rustc but it would requires adding the C++ reverse dependencies to all rust packages. Instread, we add the C++ dependency to BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS only when a musl toolchain is used. So we can still install a prebuilt rust compiler but without the rust standard library (rust-std). Usually we should not add toolchain dependencies in a _ARCH_SUPPORTS option but BR2_PACKAGE_HOST_RUSTC_TARGET_TIER... options contains already some BR2_TOOLCHAIN_USES_GLIBC or BR2_TOOLCHAIN_USES_MUSL.

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