A note is added to tie off the discussion on why moving _FORTIFY_SOURCE related flags into the toolchain wrapper doesn't currently work. - Currently -D_FORTIFY_SOURCE and optimizations are passed through CFLAGS - Packages like linux-tools ignore CFLAGS entirely and some autotools toolchain testing cases dependent on not using CFLAGS. - If FORTIFY_SOURCE is passed through the wrapper, then linux-tools will no longer be able to ignore it, because it's enforced at a lower-level and since the optimization -Os/g/1/2/3 are via CFLAGS, there is no optimization flag set. Therefore linux-tools will do all its configuration tests with FORTIFY_SOURCE forcefully enabled at the wrapper level, but no optimization enabled, and consequently tests will fail.

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