In the case of functions, big 'T's ;-) Loosely: Definitions. One thereof. Multiple definitions means you have to make an executive decision about which lib was intended, and no definition implies "go download missing package" or "bad config wrong machine". nm -A --defined-only `find /lib -name '*.a'` | grep umoddi3 [snip path]/libgcc.a:_umoddi3.o:00000000 b .bss /libgcc.a:_umoddi3.o:00000000 d .data /libgcc.a:_umoddi3.o:00000000 ? .stab /libgcc.a:_umoddi3.o:00000000 ? .stabstr /libgcc.a:_umoddi3.o:00000000 t .text /libgcc.a:_umoddi3.o:00000000 t ___clz_tab /libgcc.a:_umoddi3.o:00000000 t ___gnu_compiled_c /libgcc.a:_umoddi3.o:00000100 T ___umoddi3 /libgcc.a:_umoddi3.o:00000000 t gcc2_compiled ...implies "-lgcc" is missing from the link line.
