It doesn't matter. If you don't have one, make an empty one. The point
is, VC++ isn't smart enough to understand that a project is a C++
project if there are no files with a .cpp extension in it, so it won't
show the C++ configuration options.

That should not be necessary. You can reference the built MySQL++
library anywhere on the hard drive.

i copied util.h

That's only used by the examples. The only headers you need are in the
lib subdir.

i got no errors during compiling, but i get

Did you add the MySQL++ library to the list of libraries linked to the
program?

My guess is that you haven't linked against the mysqlpp library. Make sure
mysqlpp.lib is in the "Additional Dependencies" setting under
"Linker->Input", check that the path to the library is included in the
"Additional Library Directories" setting under Linker->General.

Subject: Using MySQL++ in Your Own Projects

I compiled the library and the sample1 application and
it works fine. The problem is, that i can't built my
own project...
I read in readme file that i should "Add a .cpp file
to the solution so it _knows_ it's a C/C++
solution."....Which .cpp file is that? I copied the
lib directory to my project, i copied util.h and
change the project setting similar to sample1 project
settings...i got no errors during compiling, but i get
a lot of linking errors. Any idea what is wrong?

I am using winxp sp2, visual studio 2005,
mysql++-2.1.1 and mysql-essential-5.0.26-win32.
