The efivar build process starts by building one tool for the host, which is needed for the rest of the build. This tool currently fails to build with old gcc versions because the gcc.specs used by efivar specifies -std=gnu11. To address this, this patch: - passes 'gcc_flags=' to the host build, so that the custom gcc specs are not passed. They are in practice not needed for the build of the simple makeguids host utility. - passes -std=gnu99 instead of -std=c99 in the build of host makeguids, because the source code uses anonymous structs and unions, which requires std=gnu99 and not just std=c99 In addition, the build by default assumes that the target toolchain is LTO capable, and that therefore you can call gcc-ar, gcc-nm and gcc-ranlib. This fails short when the target toolchain is for example gcc 4.7. To address this, we explicitly specify AR, NM and RANLIB to be used, but pass them as make options instead of in the environment, in order to override the values specified in the package Makefile.

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.
