The buildroot internal toolchain now adds a wrapper. When we use a buildroot toolchain as an external toolchain, we want to bypass this wrapper and call the compiler directly, for two reasons: 1. The options added by the wrapper are not necessarily appropriate when it is reused as an external toolchain. For instance, ccache may have been enabled while building the toolchain but not when using it as an external toolchain. 2. Currently, the wrapper expects to reside in .../usr/bin, but when used as an external toolchain it will be in .../ext-toolchain/bin. Therefore, the wrapper can't find the real binary and sysroot anymore. To bypass the wrapper, we check for the existence of *.br_real files in the external toolchain directory. If any such file exists, the wrapper will add the .br_real suffix for all the wrapped files. Note that the wrapper doesn't check if the *.br_real exists for each individual wrapped file, it just assumes that all wrapped files have a corresponding .br_real. This is currently true but that may change in the future of course. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> 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.
