When generating a random configuration, also check the host dependencies for that configuration and error out if it fails. This is mainly intended for the autobuilders, so they don't try to build a configuration for which the necessary host packages are not installed. Instead of erroring out, we could also generate a different random config. However: - When called for the autobuilders, the autobuild-run script will anyway just attempt another build. The only difference is that a warning will be printed in this autobuild log now. This warning is in fact quite useful to hint that the autobuilder could benefit from intalling this additional host package. - When called manually, the user may in fact want to install the missing host package and continue with the saved random config.

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 Freenode IRC.
