Hi,
All undefined references refer to TKLCAF.lib.
It seems you should check additional libraries directories
and additional dependencies of your project.

By the way, how to generally determine the missing library from the link errors?

Hi,
For example you got a message like next:
"error LNK2001: unresolved external symbol "protected: virtual void __thiscall TDocStd_Application:: ...."
You would like to know which library is missing.
For this you should find which library contains unit named "TDocStd".
In OCCT file named "PACKAGES" contains a list of units.
So, you may simply grep OCCT sources with two keys: key1(file name) = PACKAGES, key2(unit name) = TDocStd.
