I looked at the output of this command: c++filt < libgtkmathview0c2a_i386 | grep MISSING I see lots of mentions of SmartPtr and a few of TemplateBuilder. ComputerModernShaper seems to be gone. There are some std::* functions gone, but I'm not sure why libgtkmathview should be exporting stuff from libstdc++, so that is probably a good thing (apart from being an ABI change). -- bye, pabs http://wiki.debian.org/PaulWise
