我从 gcc 收到错误。错误是:
warning: implicit declaration of function ‘glCreateShader’ [-Wimplicit-function-declaration]
137 | unsigned int vertex_shader = glCreateShader(GL_VERTEX_SHADER);
我包括标题如下:
ath.h>
#include <time.h>
#include <GL/freeglut.h>
#include <GL/gl.h>
然后我编译程序如下:
gcc main.c -lglut -lGL -lGLEW -lGLU -lm -o snakeGame
顺便说一句,我正在使用 Linux。我的主要功能代码在这里:
int main(int argc, char **argv){
srand(time(NULL));
for (int i=0; i<snake_size; ++i){
snake[i] = 0;
}
//glut set
glutInit(&argc, argv);
glutInitWindowSize(window_x, window_y);
glutInitWindowPosition(window_position_x, window_position_y);
glutInitDisplayMode(display_mode);
int window = glutCreateWindow("snake game");
glutDisplayFunc(display_function);
glutKeyboardFunc(keyboard_function);
glutIdleFunc(idle_function);
//opengl set
unsigned int vertex_shader = glCreateShader(GL_VERTEX_SHADER);
glutMainLoop();
glutDestroyWindow(window);
printf("game over\n");
return 0;
}
很可能标题有问题,但我不知道如何解决。
