With this toolchain, guile tigger an assembler error with -Os which is probably caused by the binutils version being used: arm-none-linux-gnueabi-ld --version GNU ld (Sourcery CodeBench Lite 2014.05-29) 2.24.51.20140217 arm-none-linux-gnueabi-gcc --version arm-none-linux-gnueabi-gcc (Sourcery CodeBench Lite 2014.05-29) 4.8.3 20140320 (prerelease) Nowaday, even with a Buildroot internal toolchain using the oldest Binutils GCC version (2.25.1 and 4.8.6), guile build fine with -Os. So, force -O2 when this toolchain is used and BR2_OPTIMIZE_S is set.

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
