Protecting licensing implementation in C++

Question

What ways are there to protect licensing enforcement mechanisms in C/C++?

I know of:

• Using macros (but that make the code difficult to maintain)
• Linking statically
• Obfuscating symbol names

Other methods I am not sure about:

• Using C++ templates
• Using inline functions

It's usually a good idea to keep your code as clean as possible and rely on a third party tool to protect your code. google for "c++ obfuscator" to find such tools.
