Buildroot currently installs openjdk-bin to $(HOST_DIR)/ instead of the more traditional (for java installations) $(HOST_DIR)/usr/lib/jvm. As described in https://bugs.busybox.net/show_bug.cgi?id=13001 "Openjdk-bin provides it's own libfreetype.so and places it into $(HOST_DIR)/lib/. This library causes build failures with the host-xapp_mkfontscale package due to the overwritten libfreetype.so. mkfontscale.o: In function `doDirectory': mkfontscale.c:(.text+0x1a80): undefined reference to `FT_Get_BDF_Property' collect2: error: ld returned 1 exit status Reproducing the error is done by repeating the following steps. make host-freetype make host-openjdk-bin make host-xapp_mkfontscale" There are two options for fixing this problem: 1) add host-freetype and host-lksctp-tools as dependencies to host-openjdk-bin and then remove the provided libfreetype.so and libsctp.so libraries in a post_extract_hook. 2) change the installation directory from $(HOST_DIR)/ to $(HOST_DIR)/usr/lib/jvm just like the target OpenJDK package and copy the entire source directories contents to the above location. The second option provides the following advantages: - the directory structure is consistent with how we handle the target OpenJDK. - the HOST_OPENJDK_BIN_INSTALL_CMDS step is simplified. - packages such as Maven require directories of which we are currently not copying. These missing directories cause programs such as Maven to crash when running with an error such as "Can't read cryptographic policy directory: unlimited." - does not miss any other libraries that solution 1 would not cope with (e.g. libzip.so from host-libzip, or libnet.so from not-yet existing host-libnet, or libsctp.so from not-yet existing host-lksctp-tools) Because the second option is both simple, easier to implement, is low-impact, and fixes the problems described above wholly, it is the best to implement. To implement the above changes, we must also modify the following files in the same patch to match the host's new directory paths: - openjdk.mk - openjdk-jni-test.mk - openjdk-hello-world.mk To avoid having to change all those packages in the future, expose two new variables, HOST_OPENJDK_BIN_ROOT_DIR which contains the path where the openjdk-bin was installed in, and JAVAC, which contains the path to the javac compiler (modeled after the way the autoconf et al. variables are set and exposed).

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
