You're not understanding static linking, then.  Static linking makes the 
MySQL++ binary code part of your executable.  Dynamic linking, by 
contrast, keeps the MySQL++ binary code elsewhere, and your code only 
links to it when the program runs.

The LGPL provisions basically allow your users to replace parts of 
MySQL++ if they want, without affecting your program.  They cannot do 
this if you give them an executable with MySQL++ statically linked.

There is a workaround: you can also give your users object files for 
your program, so they can relink it to MySQL++ themselves.  This would 
allow you to statically link to MySQL++, but most people find providing 
*.o files too odious.

If you want to argue further about this, I'm not interested.  See the 
FAQs and documentation on gnu.org, and/or consult a lawyer.
