MySQL++ MinGW - installation problem

[CppMaster]

Hello Everyone!
This is my first post on this forum.
I have a problem with installing MySQL++ on MinGW. I have followed by this instruction: http://www.cplusplus.com/forum/windows/5259/#msg23277 and I have stopped on this:

Now we can continue and build for DEVC++ and mingw.
Still in the dos box - change directories back to your mysql++-3.0.6
and run the command as given in the Building the Library and Example Programs of the README-MinGW.txt file (mingw32-make -f Makefile.mingw).

When I this, I receive those errors:

C:\MinGW\mysql++-3.1.0>mingw32-make -f Makefile.mingw

What shall I do to solve my problem?

Do you have any include options in your make file?
Are the paths to the libraries correct?
If so, are the libs in those directories?
