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.
