c++ - G++混淆了将结构返回为结构初始值设定项的函数原型(prototype)

编译项目时，出现以下错误：

drawplant.h: In function 'Matrix3f current_matrix()':
drawplant.h:26:1: error: only constructors take member initializers
 Matrix3f mmmult(Matrix3f, Matrix3f);

这是drawplant.h：

#ifndef _DRAWPLANT_H_
#define _DRAWPLANT_H_

/* Functions implemented in drawplant.cpp */

#define PI 3.14159265358


struct Vector3f{
    GLdouble v[4];
} typedef Vector3f;

struct Matrix3f{
    GLdouble m[16];
} typedef Matrix3f;

extern int depth;

void drawPlant();
void push();
void pop();
//void rotate(GLdouble, GLdouble, GLdouble, GLdouble, GLdouble, GLdouble, GLdouble);
//void translate(GLdouble, GLdouble, GLdouble);
//void scale(GLdouble, GLdouble, GLdouble);
Matrix3f current_matrix(void):
Matrix3f mmmult(Matrix3f, Matrix3f);
Vector3f mvmult(Matrix3f, Vector3f);
#endif  /* _DRAWPLANT_H_ */

最佳答案

尝试改变

Matrix3f current_matrix(void):

至

Matrix3f current_matrix(void);

注意最后的分号。
