How can I debug C++ templates effectively?
Debugging C++ templates can be tricky due to their complexity. You can use static assertions, type traits, and template specialization to help identify issues.
What are static assertions and how do they help?
Static assertions allow you to check conditions at compile time. If the condition fails, it generates a compile-time error, helping you catch issues early.
Can you give me an example of using static assertions?
Sure! Here's a simple example: static_assert(sizeof(T) > 0, "Type T must be non-empty");
This checks that the type T is valid.
What about debugging template instantiation errors?
For instantiation errors, you can enable verbose template instantiation logging in your compiler settings to get more detailed error messages.
