Up to now we created the $(HOST_DIR)/usr compatibility symlink as part of the creation of $(HOST_DIR) itself. However, when the user specifies a custom BR2_HOST_DIR, it is possible that the directory already exists so this rule will never trigger. Therefore, add an explicit rule for creating $(HOST_DIR)/usr and add this rule to the dependencies of the dirs target. HOST_DIR itself goes back to the standard rule for directories. The order-only dependency of STAGING_DIR isn't needed any more either: HOST_DIR is implicitly created if needed by mkdir -p, and we don't need to trigger the HOST_DIR rule any more if the directory already exists.

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
