Hi all;
When I run the example in its original directory, I have no problems.
When I wrap the example in my source, the source compiles but fail to
link with a certain Library as shown in the output below. What I want is
to get out the query results and use them in normal C++ environment.
Your help will be greatly appreciated. I am using linux Redhad version
6.2
and mysql++ version 1.7.8
Thanx in advance
Tiwonge
