C++ map: expected initializer before ‘<’ token

I'm getting this error in a header file:

error: expected initializer before ‘<’ token

class MyEntity;
typedef std::map<uint16,MyEntity*> myList_t;

I figured it's not seeing the ma开发者_Python百科p include, but at the top of that header file is:

#include <list>
#include <map>

In another header file:

typedef unsigned int               uint32;

Any ideas?

g++ (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)

There was a macro named map that was causing a conflict.

In your actual code (not your simplified example) you are probably missing a ; from the end of the line before the typedef. This is usually what it means when I get that kind of cryptic error and I can almost reproduce your message by putting another underminated typedef above it:

q.cc:8: error: expected initializer before 'typedef'

My first guess was that class MyEntity was a full definition (not a forward declaration) and was missing the ; but I get a slightly different error for that.
