I'm using MingW on Win2K. Mysql++ 1.7.23. Using MingW Developer Studio for creating projects and as a programming IDE.

Created a number of projects with a single header and source file and linked it to the MySQLpp dll without any problem. However, when I create a project with more than one set of header and source files, I have the following link errors. Would greatly appreciate it if you could provide some pointers.
