(libscfiltlo.so and libooxlo.so) The undefined symbol is: x4 ~ # c++filt _ZThn40_N3utl28OSeekableOutputStreamWrapper7acquireEv non-virtual thunk to utl::OSeekableOutputStreamWrapper::acquire() But the symbol is defined in workdir/CxxObject/unotools/source/streaming/streamwrap.o and adding this object file to the link object file list fixes the problem. So it looks like a LibreOffice issue in this case.
