Question

I just reorganized the code for a project and now I’m getting errors I can’t resolve. This header is included by a .cpp file trying to compile.

#include "WinMain.h"
#include "numDefs.h"
#include <bitset>

class Entity
{
public:
    Entity();
    virtual ~Entity();

    virtual bitset<MAX_SPRITE_PIXELS> getBitMask();
    virtual void getMapSection(float x, float y, int w, int h, bitset<MAX_SPRITE_PIXELS>* section);
};

I’m getting these compiler errors for the declaration of Entity::getBitMask():

error C2143: syntax error : missing ‘;’ before ‘<‘

error C2433: ‘Entity::bitset’ : ‘virtual’ not permitted on data declarations

error C4430: missing type specifier – int assumed. Note: C++ does not support default-int

error C2238: unexpected token(s) preceding ‘;’

There are more similar errors for the next line as well. It seems like bitset isn’t getting included but it clearly is? I can’t figure out what’s going wrong. WinMain.h includes windows.h, and numDefs.h includes nothing.

Using MS Visual C++ 2008.

Answer 1

Declare the bitset as std::bitset<MAX_SPRITE_PIXELS>.
