我试图把所有GLFW3初始化代码从主要到单独的文件。 当我运行代码时,我在glew init函数上得到EXC_BAD_ACCESS,因为GLFW无法创建窗口。在代码分离之前,一切都很好。是否有可能在其他功能GLFW设置代码?GLFW3创建窗口返回空
我开始学习C和openGL,所以任何帮助将不胜感激。
这是window_manager.h
typedef struct Window_manager
{
GLFWwindow *window;
GLuint window_width;
GLuint window_height;
const char *window_title;
} Window_manager;
Window_manager *set_up_window(GLuint width, GLuint height, const char *title);
守则window_manager.c
Window_manager *set_up_window(GLuint width, GLuint height, const char *title)
{
Window_manager *win_man = malloc(sizeof(Window_manager));
// Init GLFW
//glfwSetErrorCallback(error_fiutallback);
if (!glfwInit())
exit(EXIT_FAILURE);
// Set all the required options for GLFW
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
win_man->window_width = width;
win_man->window_height = height;
win_man->window_title = title;
win_man->window = glfwCreateWindow(win_man->window_width, win_man->window_height, win_man->window_title, NULL, NULL);
glfwMakeContextCurrent(win_man->window);
// Set the required callback functions
//glfwSetKeyCallback(win_man->window, key_callback);
return win_man;
}
而且main.c中
int main(int argc, const char * argv[])
{
Window_manager *win_man = set_up_window(800, 600, "fjut");
glewExperimental = GL_TRUE;
// Initialize GLEW to setup the OpenGL Function pointers
GLenum err = glewInit();
if (GLEW_OK != err)
{
//Problem: glewInit failed, something is seriously wrong.
printf("Error: %s\n", glewGetErrorString(err));
}
fprintf(stdout, "Status: Using GLEW %s\n",
glewGetString(GLEW_VERSION));
您是否尝试过设置GLFW_CONTEXT_VERSION_MINOR? – BDL
@BDL glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR,3);这条线完美地工作。 感谢您的帮助。 – DontKnowWhatIsWhat
