GLEW 和 glfw 编译错误:未定义对符号“XConvertSelec

问题描述

我正在尝试编译此代码:

I'm trying to compile this code:

#include <stdio.h>
#include <stdlib.h>

#include <GL/glew.h>

#include <GLFW/glfw3.h>
GLFWwindow* window;

#include <glm/glm.hpp>
using namespace glm;

int main( void )
{
    // Initialise GLFW
    if( !glfwInit() )
    {
        fprintf( stderr, "Failed to initialize GLFW
" );
        return -1;
    }

    glfwWindowHint(GLFW_SAMPLES, 4);
    glfwWindowHint(GLFW_RESIZABLE,GL_FALSE);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    // Open a window and create its OpenGL context
    window = glfwCreateWindow( 1024, 768, "Playground", NULL, NULL);
    if( window == NULL ){
        fprintf( stderr, "Failed to open GLFW window. If you have an Intel GPU, they are not 3.3 compatible. Try the 2.1 version of the tutorials.
" );
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);

    // Initialize GLEW
    if (glewInit() != GLEW_OK) {
        fprintf(stderr, "Failed to initialize GLEW
");
        return -1;
    }

    // Ensure we can capture the escape key being pressed below
    glfwSetInputMode(window, GLFW_STICKY_KEYS, GL_TRUE);

    // Dark blue background
    glClearColor(0.0f, 0.0f, 0.4f, 0.0f);

    do{
        // Draw nothing, see you in tutorial 2 !

        // Swap buffers
        glfwSwapBuffers(window);
        glfwPollEvents();

    } // Check if the ESC key was pressed or the window was closed
    while( glfwGetKey(window, GLFW_KEY_ESCAPE ) != GLFW_PRESS &&
           glfwWindowShouldClose(window) == 0 );

    // Close OpenGL window and terminate GLFW
    glfwTerminate();

    return 0;
}

这是我找到的有关 OpenGL 的教程中的代码，在谈到 OpenGL 时，我主要使用 Java 进行编程，但我想尝试一些新的东西，所以我尝试使用 C++.

It's a code from a tutorial I found about OpenGL, I program mostly in Java when it comes to OpenGL, but I wanted to try something new so I went to try in C++.

我在这个项目中使用 QtCreator.起初我包含了 GLEW 和 glfw3 库:

I'm using QtCreator for this project. At first I included GLEW and glfw3 libraries:

对于 glfw 库文件也是如此.

And the same for the glfw library file.

然后，当我尝试编译程序时，出现此错误:

And then, when I try compiling the program I get this error:

在文本中:

$ /home/sapir/Qt/5.4/gcc_64/bin/qmake -spec linux-g++ CONFIG+=debug -o Makefile ../Test/Test.pro

我厌倦了在论坛和这里寻找答案，但我找不到任何可以解决此问题的方法.有人有什么想法吗?

I tired searching for an answer in forums and here, but I couldn't find anything that solved this problem. Anybody got any Ideas?

添加后

-lXxf86vm -lXrandr -lGL -lGLU -lXi

对于 gcc 编译器，我得到一个不同的错误，其中包含:

to the gcc compiler, I get a different error, which contains:

/usr/bin/ld: /home/sapir/Dropbox/Development/Computer/openGLTest/Test/../../../../../../../usr/local/lib//libglfw3.a(x11_window.c.o): undefined reference to symbol 'XConvertSelection'

这是我的 .pro 文件:http://pastebin.com/yhkV7nn7

推荐答案

好的，经过一番研究，我发现我得到的 DSO 错误意味着我实现的包含的顺序不正确导致编译失败.

Ok, after some research I found that the DSO error which I got means that the order of the includes I've implemented is incorrect and cause the compilation to fail.

所以我所做的就是使用命令:

So what I did is I used the command:

pkg-config --static --libs x11 xrandr xi xxf86vm glew glfw3

为了得到我需要的包，它们才能以正确的顺序运行.

To get the packages I need for them to run and in the right order.

然后我相应地编译了项目.就是这样:)

Then I compiled the project accordingly. That's it :)
