Subject:Problem linking multiple files with MySQLpp dll
View as plain text  
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.

C:\Zahroof\EAZ\Flow_Entrance\Debug\GradContract.o(.text+0x116): In
