![]() Currently, use of -fstack-protector-strong is only available for gcc starting with 4.9, on the assumption that it appeared with that version. Although this is true, it happens that quite a few vendors will have back-ported -fstack-protector-strong to older gcc versions (at least 4.8 seen in the wild). Remove the guard against gcc>=4.9, and expand the help text. Note: we could have changed the guard to something like: depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_9 || BR2_TOOLCHAIN_EXTERNAL_CUSTOM However, the latest gcc we support in the internal toolchain now *is* gcc-4.9, and similarly all external toolchains except Sourcery ARM are 4.9 or higher. So except for the Sourcery toolchain, the condition would have always been true. For that one toolchain, we can allow it to hit the SSP check, and just drop the condition entirely.

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
