This is a step towards eliminating $(HOST_DIR)/usr. It allows us to convert all packages installing things into $(HOST_DIR)/usr/lib without affecting the rest. To allow compatibility with packages that still use $(HOST_DIR)/usr as the prefix, create a symlink from usr/lib to ../lib. Note that the symlink creation will break when $(HOST_DIR)/usr/lib already exists as a directory, i.e. when rebuilding in an existing output directory. This is necessary: if we don't break it now, the following commits (which remove the usr part from various variables) _will_ break it. At the same time as creating this symlink, we also have to update the check-host-rpath script to accept both $(HOST_DIR)/usr/lib and $(HOST_DIR)/lib, because depending on how the package derives the path, it may be different. Since there are some dependency chains that involve $(STAGING_DIR), $(STAGING_DIR) may in fact be created before $(HOST_DIR). Since $(STAGING_DIR) is a subdirectory of $(HOST_DIR), it is possible that the newly added rule for $(HOST_DIR) never triggers. To make sure that the rule does trigger, add an order-only dependency from $(STAGING_DIR) to $(HOST_DIR).

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
