With BR2_PER_PACKAGE_DIRECTORIES=y, we have the following code in the main Makefile: target-finalize: $(PACKAGES) $(TARGET_DIR) host-finalize @$(call MESSAGE,"Finalizing target directory") $(call per-package-rsync,$(sort $(PACKAGES)),target,$(TARGET_DIR)) $(foreach hook,$(TARGET_FINALIZE_HOOKS),$($(hook))$(sep)) The per-package-rsync call creates the global $(TARGET_DIR) from the per-package $(TARGET_DIR). Then, we call the TARGET_FINALIZE_HOOKS. One of the TARGET_FINALIZE_HOOKS, PURGE_LOCALES, remove locales that are not desired by the user. It does so using a loop with the $(wildcard ...) function. However, the $(wildcard ...) function is expanded at the moment the rule is evaluated. And with per-package directory, at the time the rule is evaluated, the global $(TARGET_DIR) is empty, so $(wildcard ...) will return nothing. It is indeed only after the call to per-package-rsync that the TARGET_DIR will be populated. This commit fixes that by moving away from $(wildcard ...) and use a shell test instead, since we are anyway in big block of shell code. With this, locales are properly purged again when BR2_PER_PACKAGE_DIRECTORIES=y.

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.
