Hmm, it surely worked for me for both, with and without in-tree binutils (you don't say which variant you saw the failure with). > For some reason, I have > grep OBJCOPY *gcc/Makefile > gcc/Makefile:ORIGINAL_OBJCOPY_FOR_TARGET = > prev-gcc/Makefile:ORIGINAL_OBJCOPY_FOR_TARGET = > stage1-gcc/Makefile:ORIGINAL_OBJCOPY_FOR_TARGET = What about the corresponding ORIGINAL_NM_FOR_TARGET? And could you provide one of the config.log instances? Jan
