Previously, it was possible to select an external toolchain that did not support the GCC arch tuning the user had selected. This is problematic because it can lead to confusing error messages during builds [0]. Now, external toolchain selections will be filtered to only those that support the required GCC version specified by the target arch tuning. Note: this patch does not touch the Bootlin toolchain config file as it is generated by a script. Additional note: there is "soft" support for toolchains prior to GCC 4.8 but there are no accompanying BR2_ARCH_NEEDS_GCC_AT_LEAST_X symbols. Instead of adding those, just use BR2_ARCH_NEEDS_GCC_AT_LEAST_4_8 which is the minimum GCC version with claimed support [1].

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
