Currently we only test a limited set of toolchains that are mostly prebuilt, add a flag to allow using randconfig for randomizing additional toolchain settings instead of randpackageconfig. To avoid invalid configs we need to add additional config validation filtering and fixups. Although the loop around 'make randconfig' attempts does make sure we eventually end up with a valid configuration, there is a bias towards e.g. disabling the kernel. It would be possible to e.g. always force BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y, but that removes the possibility for a toolchains-csv config to add a valid custom defconfig. (Note that currently this isn't possible anyway since 'make randpackageconfig' is used if a toolchains-csv is provided, but eventually we want to use 'make randconfig' also if a toolchains-csv is provided.)

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.
