Currently, calling foo-reconfigure for a kconfig-based package will not re-trigger the configuration (kconfig-wise) step for the package. This can be problematic when using an override-srcdir suring development and the content of the veride-srcdir changes (e.g. on a rebase, a merge, or during a bisect). This is because the configuration (kconfig-wise) of the package is not done in the _CONFIGURE_CMDS block, but as a separate action that is not part of any step [0]. So, be sure to remove the stamp file .stamp_kconfig_fixup_done during the foo-clean-for-reconfigure rule, so that the configuration is applied again with the new source tree. We use another rule, foo-clean-kconfig-for-reconfigure, because we do not want to override the default foo-clean-for-reconfigure rule, and we have no way to add conditional commands to it. [0] The reasons it was not done are not entirely clear in my head, but IIRC that was not working at the time we tried with Thomas DS.

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
