Older toolchains that use binutils <= 2.23.2 are affected by binutils bug #14887 (https://sourceware.org/bugzilla/show_bug.cgi?id=14887), where: someinstruction [ foo, something ] is not accepted, due to the whitespace after [ and before ], causing the following build failures for OpenBLAS: ARM register expected -- `pld [ r1,#512 ]' Since we don't have any mechanism to add dependencies on binutils versions, we work around this problem by patching the code to remove the problematic whitespaces. As there are many many instances of this in the ARM assembly code of OpenBLAS, we use a sed expression to make this modification rather than a patch. Fixes: http://autobuild.buildroot.net/results/43e50b480b4aea0fdec745d7875c85377c114cac/ [Peter: use single quotes in sed invocation] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.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
