Michael,
After VC++ automatically upgrades the supplied files to a solution you
need to set up the release and debug configurations as per the
instructions (you said you have already done this for the release
version). Change your build type to Debug and rebuild the solution. This
will create a debug folder under mysql++-2.2.2 eg \mysql++-2.2.2\debug.
In there will be a debug version of mysqlpp.dll. You can then change the
build type to Release, make sure you rebuild the solution and a
\mysql++-2.2.2\release folder will be created with a release version of
mysqlpp.dll. Just copy the versions from the appropriate folder to your
own project folders. Don't worry about the install.bat - I found it
didn't work properly on Windows (don't know about Linux and I haven't
downloaded 2.2.3 yet).
