在将debian从stretch升级到buster并将GLEW
从2.0.0-3
升级到2.1.0-2
之后,我的应用程序停止工作。更准确地说,只有黑屏可见。着色器编译成功,但仅此而已。以下是我程序的代码节选:
void initGL() {
std::cout << "Starting GLFW context, OpenGL 3.3" << std::endl;
// Init GLFW
if (!glfwInit()) std::cout << "GLFW init failed";
// Set all the required options for GLFW
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);
// Create a GLFWwindow object that we can use for GLFW's functions
window = FULLSCREEN == true ?
glfwCreateWindow(WIN_W, WIN_H, "Algine", glfwGetPrimaryMonitor(), nullptr) :
glfwCreateWindow(WIN_W, WIN_H, "Algine", nullptr, nullptr);
glfwMakeContextCurrent(window);
// Set the required callback functions
glfwSetKeyCallback(window, key_callback);
glfwSetWindowSizeCallback(window, window_size_callback);
// Set this to true so GLEW knows to use a modern approach to retrieving function pointers and extensions
// glewExperimental = GL_TRUE;
// Initialize GLEW to setup the OpenGL Function pointers
if (glewInit() != GLEW_NO_ERROR) std::cout << "GLEW init failed\n";
glEnable(GL_DEPTH_TEST);
glDepthMask(true);
//glCullFace(GL_BACK);
}
渲染:
while (!glfwWindowShouldClose(window)) {
currentTime = glfwGetTime();
frameCount++;
// If a second has passed.
if (currentTime - previousTime >= 1.0) {
// Display the frame count here any way you want.
std::cout << frameCount << " fps\n";
frameCount = 0;
previousTime = currentTime;
}
// Check if any events have been activiated (key pressed, mouse moved etc.) and call corresponding response functions
glfwPollEvents();
display();
glfwSwapBuffers(window);
}
我正在使用Debian Buster;我的应用程序中有GLFW + GLEW
任何想法可能是什么问题?我将非常感谢您的帮助!
更新:将系统回滚到Debian Stretch。之后,我手动将
glew
更新为2.1.0-2
版本(位于Buster上),一切正常。如果问题不在驱动程序中,也不在我使用的库中,那么问题出在Debian Buster本身吗? 最佳答案
问题解决了。事实证明,问题出在新的glm
中。我手动将glm
版本从0.9.9~a2-2
(Buster)还原为0.9.8.3-3
(Stretch),一切开始正常进行。
关于linux - 更新GLEW之后,窗口变成只有黑色,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/53575203/
