C++ Error: Underscores in Function Names

[ehrenfest]

I got the following error when I tried to compile some code:

error: `angle_between' cannot be used as a function

I changed the function name to "function1" and it compiled. Since when did C++ not like underscores in function names?

The underscore isn't a problem ( although leading and trailing ones can cause issues)
Are you sure you haven't got a angle_between() typo somewhere ?

Can you post the line the compiler complains about?

Yeah, it "looks" fine. Maybe you should post the code and where the compiler cries.

Grep your sources looking for angle_between, could be it was defined earlier as something else.
