This line in itself is not problematic, but somehow the arguments that g++ passes to cc1plus are. Which makes me wonder, what does '@media_driver/CMakeFiles/iHD_drv_video_COMMON.dir/agnostic/common/cm/cm_array.cpp.o.rsp' part do? I haven't seen such syntax before. I suspect that becomes a very long list of files, each with a full path that exceeds the limits anywhere with a long-ish build prefix, not just one made by bitbake-setup. Alex
