test.hpp:

class Test {
public:
	double test (	unsigned int i,
			double * buffer,
			void * argument = NULL) const;
};

test.cpp:

#include "test.hpp"

output:

Quote:
g++ -c test.cpp test.hpp:5: error: ‘NULL’ was not declared in this scope

This suddenly started. Code that compiled yesterday now fails with this error. What's going on?

NULL is not a keyword; it is a macro. Are you including a header which defines NULL?

exactly what the error says. NULL isn't defined. i believe it's defined in quite a few header files so you probably just removed an #include and now it doesn't know what you're talking about. you can just define if yourself if you need to.

Try:

#include <cstddef>

Or you could try spelling it the modern (for now) way: 0.

Oh, and what are you doing with those void*s in my C++? :(
