我正在使用Ubuntu 14.04和GNU G ++命令。
code: 码:
#include <GLFW/glfw3.h>
int main(void) {
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
GLFWwindow* window = glfwCreateWindow(800, 600, "OpenGL", NULL, NULL);
glfwMakeContextCurrent(window);
while(!glfwWindowShouldClose(window)) {
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
}

You should not link to glfw
, but link to glfw3
. 您不应链接到
glfw
,而应链接到glfw3
。 As here: 如这里:
g++ display.cpp -lglfw3 -o display.out
