okay, so you want to load an existing document...

the problem is that the DrawViewShell is not annotated with 
SD_DLLPUBLIC, hence it and its member functions are not visible to the 
unit test.

there are 2 obvious options:

1. make it SD_DLLPUBLIC

2. move your test to "CppunitTest_uimpress", which is built in a special 
way so that it can access all internal functions of Library_sd, but it 
is unable to access anything from Library_sdui or Library_sdfilt.

now i don't know if it is possible to load a document from uimpress 
test; probably not with the same functions as are used in the other tests...
