obj/Release/SERVER/DBConnection/zdb_connection/cstzdbresultset.o: In function `CSTZDBResultSet::is_null(unsigned int) const':

/home/bsr/work/Development/source_cs_server/SOURCE/SERVER/DBConnection/zdb_connection/cstzdbresultset.cpp:15: undefined reference to `ResultSet_isnull(ResultSet_S*, int)'

/home/bsr/work/Development/source_cs_server/SOURCE/SERVER/DBConnection/zdb_connection/cstzdbresultset.cpp:18: undefined reference to `Exception_throw(Exception_T const*, char const*, char const*, int, char const*, ...)'

Same problem is seen with all the symbols in the ResultSet.c. I have followed the instructions to build the library and is installed in /usr/local/lib. However, I am not seeing the same with Connection class and some of the exception macros. Please suggest me how to fix this problem.
