Daniel,
Well if the command....
LD_TRACE_LOADED_OBJECTS=1 LD_BIND_NOW=1 LD_TRACE_PRELINKING=t \
/lib/ld-2.3.2.so /usr/lib/libefs.so.1 | grep ^undefined
...is correct, the same thing can be obtained a lot simplier
with only...
ldd -d -r /usr/lib/libefs.so.1 | grep ^undefined
At least I seem to get the same symbols here with that
and 'ldd -d -r' is what Jakub recommended for searching for
these undefined weak symbols.
