Detecting the boost program_options library is broken: checking for the Boost program_options library... no configure: error: cannot find the flags to link with Boost program_options config.log shows the reason, libatomic is missing: conftest.o: In function `boost::detail::sp_counted_base::release()': conftest.cpp:(.text._ZN5boost6detail15sp_counted_base7releaseEv[_ZN5boost6detail15sp_counted_base7releaseEv]+0xc): undefined reference to `__atomic_fetch_sub_4' conftest.cpp:(.text._ZN5boost6detail15sp_counted_base7releaseEv[_ZN5boost6detail15sp_counted_base7releaseEv]+0x38): undefined reference to `__atomic_fetch_sub_4' /home/buildroot/br4/output/host/sparc-buildroot-linux-uclibc/sysroot/usr/lib/libboost_program_options.so: undefined reference to `__atomic_fetch_add_4' Please note that using LIBS=-latomic is not enough, although it fixes the configure check the bug reoccurs when linking cc-tool: CXXLD cc-tool src/application/cc_flasher.o: In function `boost::detail::sp_counted_base::weak_release()': cc_flasher.cpp:(.text._ZN5boost6detail15sp_counted_base12weak_releaseEv[_ZN5boost6detail15sp_counted_base12weak_releaseEv]+0xc): undefined reference to `__atomic_fetch_sub_4' We need to add -latomic to CXXFLAGS to both fix configure and linking.

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
