What is wrong there?
apparently GCC can't find the type information for GraphicViewShell
because it isn't exported from the shared library "sd".
it is needed because of dynamic_cast<sd::GraphicViewShell*> in the test.
you could use SAL_DLLPUBLIC_RTTI on GraphicViewShell, which will export
just enough so that dynamic_cast and type_info works, or use
SD_DLLPUBLIC on it, which will make all its member functions available
as well.
Both do not work, SD_DLLPUBLIC does not compile here, and
SAL_DLLPUBLIC_RTTI fails too, see Jenkins for patch set 5.
hmmm...
clang plugin dyncastvisibility did trigger. dynamic_cast from
"sd::ViewShell" with hidden type visibility to "sd::GraphicViewShell"
with default type visibility
... so probably you'd need to put the SAL_DLLPUBLIC_RTTI on the
superclass sd::ViewShell as well.
