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.

probably the issue doesn't happen with MSVC because it implements 
dynamic_cast differently, so unless you want to set up a Linux VM, 
you'll have to rely on Jenkins...
