There are two legitimate cases to prefer ifdef over ifeq in package recipes: command-line overrides are allowed for busybox and uclibc configs. Except for that, all package in tree already use ifeq, so warn the developer adding/changing a package to use ifeq instead of ifdef, in order to keep consistence across packages. file.mk:2: use ifeq ($(SYMBOL),y) instead of ifdef SYMBOL file.mk:5: use ifneq ($(SYMBOL),y) instead of ifndef SYMBOL The difference between ifeq and ifdef is that ifdef doesn't expand recursively. Add comments to busybox and uclibc packages to avoid a warning in such special cases.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
