Some architectures, f.e. Blackfin doesn't support to configure GCC with --with-cpu to set some CPU specific default CFLAGS (-mcpu=foo). Use a hidden config symbol to give a hint which architecture supports it, otherwise add defaults to toolchain wrapper for internal toolchains. Idea from Thomas Petazzoni. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> [Thomas: - simplify the Config.in logic with just one option named BR2_GCC_ARCH_HAS_CONFIGURABLE_DEFAULTS, defined in package/gcc in one place. - improve the organization of the code and name of variables.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

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
