C++ Linker Error on CppUnit

Question

I'm trying to compile an extension library for CppUnit.

But it gives me the following error while linking:

DatabaseAssert.cp:(.text+0x782): undefined reference to 'CppUnit::DatabaseAssert::getDBConnection(DBAdapter*)'

The included header file has the definition :

static oracle::occi::Connection* getDBConnection(DBAdapter *dbAdapter);

Any clues why I am still getting the undefined reference error?
