我正在尝试编写一个简单的程序，仅使用GLEW 2.0和GLFW 3打开一个窗口，但遇到段错误...
这是我的资料来源：
#include <stdio.h>
#include <GL/glew.h>
#include <GLFW/glfw3.h>
int main(int argc, char **argv) {
const int height = 100;
const int width = 100;
if (!glfwInit()) {
printf("Glfw failed to init\n");
return -1;
}
// 4x antialiasing
glfwWindowHint(GLFW_SAMPLES, 4);
// We want OpenGL 3.3
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
// We don't want the old OpenGL
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window;
window = glfwCreateWindow(width, height, "Tutorial 01", NULL, NULL);
if (window == NULL) {
printf("GLFW Failed to open a window. "
"Intel GPUs don't support 3.3\n");
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
glewExperimental = 1;
if (glewInit() != GLEW_OK) {
printf("GLEW Failed to initialize.\n");
return -1;
}
glfwSetInputMode(window, GLFW_STICKY_KEYS, GL_TRUE);
do {
glfwSwapBuffers(window);
glfwPollEvents();
} while( glfwGetKey(window, GLFW_KEY_ESCAPE ) != GLFW_PRESS &&
glfwWindowShouldClose(window) == 0 );
}
我用这个编译
gcc test.c -g -lGLEW -lglfw -o test
并在运行该程序时收到段错误。使用
gdb，段错误的回溯可提供0 0x0000000000000000 in ?? ()
1 0x00007ffff7ba02a7 in glxewInit () from /usr/lib64/libGLEW.so.2.0
2 0x00007ffff7ba87a3 in glewInit () from /usr/lib64/libGLEW.so.2.0
3 0x0000555555554bd4 in main (argc=1, argv=0x7fffffffdf18) at test.c:39
我在Ubuntu 17.04上，并使用Ubuntus pacakge manager安装glew / glfw
sudo apt-get install libglew2.0 libglew-dev libglfw3 libglfw3-dev
我正在遵循本教程here。如果有什么不同，我没有运行桌面管理器或合成器。我正在使用i3wm。但是，与compton合成器一起运行时，segfault仍然会发生。
最后，为了提供一些额外的信息，

谢谢你的帮助。
最佳答案
There is a bug report表示GLEW中的核心配置文件已被破坏，直到2.0.0。
因此，您应该更新GLEW。如果那不起作用，请通过将GLFW_OPENGL_CORE_PROFILE标志替换为GLFW_OPENGL_COMPAT_PROFILE切换到兼容性配置文件。
