The efivar internal build system uses flags such as -std=gnu11 , -Wmaybe-uninitialized , -flto which are available in gcc >= 4.7 only. These flags are passed both to target build and to build a host tool. For the host part, this has been worked around by overriding 'gcc_flags', but doing that for the target would remove all flags that upstream intended for the target build. Buildroot doesn't support building gcc 4.6 in its own toolchain anymore but it's possible to use an external toolchain with gcc 4.6 which would be unable to build this package. This patch adds a limitation on toolchains with target gcc >= 4.7 to make sure that the flags are available in the chosen toolchain.

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.
