The name of the missng symbol shows that some "moc" object was not
linked into the library.

While compiling QT creates meta-object file (the usally look like moc_*.cxx).
The suffix .cxx is important. It seems to me that one of these files
was not compiled/linked.

You can use microsoft's tool dumpbin to list contens of .lib .dll. .obj

Another possible problem is that you use headers from internal Qscitilla
and you mix them with binaries from newest Qscitilla version.
This can lead to very suprising segfaults.


ps. When I tried use 'WANT_INTERNAL_QSCINTILLA = 1' in cmake,  I got   
several others
errors during linking.

Can you provide these error too. I never tried to compile Tora on windows
without internal qsintilla.
