With following blackfin toolchains BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2014R1 BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2013R1 BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R2 when BR2_BINFMT_FDPIC=y ../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)': ../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void' code snippet at line 95 in elf-fdpic.h ------------------------------------------------------- unsigned long offset = p - (void*)map->segs[c].p_vaddr; ------------------------------------------------------- void pointer addition and subtraction is not allowed in C++ as it has undetermined size, however in C with language extension it is possible because sizeof void is treated as one byte. This is toolchain-specific issue. So disable package on these external toolchains. fixes: http://autobuild.buildroot.net/results/c70/c704c70ae2f066f85dd6a5fa6a73789bc358d368/ Signed-off-by: Rahul Bedarkar <rahul.bedarkar@imgtec.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.
