VS2017+OpenGL環境的配置（完結篇）
阿新 • • 發佈：2018-12-25
最近學校裡新開了一門計算機圖形學的課程，開始慢慢接觸OpenGL，今天來分享一下如何在VS2017裡配置OpenGL。
剛開始的學習必然來自度娘，不過看了好多大神的文章讓我這個初學者很懵逼，納尼！VS也要配置，配置個OpenGL這麼複雜嗎？今天小生來教大學一個萬能配置方法。

文章目錄
下載VS2017+各種依賴庫
想要玩轉openGL,手下你得有一個工具，這裡小生用的是VS2017（其他版本沒測試過），有了工具之後就開始下載各種依賴庫了。
下載地址：
開啟網址：https://www.opengl.org/resources/libraries/glut/glut_downloads.php#windows
點選 glutdlls37beta.zip即可下載。
配置 OpenGL
1、將下載的 glutdlls37beta.zip 解壓可發現裡面包含 glut.dll、 glut32.dll 、glut.lib 、glut32.lib 、glut.h 5個檔案。
2、然後找到VS2017安裝的目錄，路徑為C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\include\（路徑因人而異），建立一個名為gl的資料夾，並將解壓到的glut.h檔案複製其中。
3、再找到路徑為 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\lib\x86
glut.lib，glut32.lib複製其中。
4、最後把解壓到的glut.dll和glut32.dll複製到C:\Windows\System32資料夾內（32位系統）
或C:\Windows\SysWOW64(64位系統）。
測試
開啟VS2017，新建一個C++的Windows控制檯應用程式的空專案，將如下程式碼貼上：
#include <GL/glut.h>
void Show()
{
glClear(GL_COLOR_BUFFER_BIT);
glRectf(-0.1f, -0.1f, 0.5f, 0.5f);
glFlush();
}
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);
glutInitWindowPosition(100, 100);
glutInitWindowSize(800, 600);
glutCreateWindow("小生OpenGL測試");
glutDisplayFunc(Show);
glutMainLoop();
return 0;
}
結果
成功！
配置 GLFW
下載GLFW
開啟網址： http://www.glfw.org/download.html 下載32位版本
選擇32-bit，這裡不是按照電腦來選的，是按照vs裡面的。
1、將glfw-3.2.1.bin.WIN32\include\GLFW 資料夾裡的glfw3.h 檔案複製到 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\include\gl 中。
複製後：
2、將 glfw-3.2.1.bin.WIN32\lib-vc2015 中的 glfw3.lib、glfw3dll.lib 複製到C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\lib\x86資料夾裡。
3、將glfw-3.2.1.bin.WIN32\lib-vc2015 資料夾裡的 glfw3.dll 複製到 C:\Windows\System32 或C:\Windows\SysWOW64 裡
下載GLAD（使用OpenGL函式）
1、開啟網址： http://glad.dav1d.de/ 如圖設定：
2、然後點選GENRATE
3、選中最後的壓縮包下載
4、把include中所有的檔案複製到C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\include 資料夾裡。
5、 src 資料夾裡glad.c 就好備用。回到VS，新建一個專案檔案，將glad.c 複製到與原始檔同一級目錄下：
6、輸入以下程式碼：
#include "glad\glad.h"
#include "gl\glfw3.h"
#include <iostream>
int main()
{
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window = glfwCreateWindow(800, 600, "小生OpenGL測試", NULL, NULL);
if (window == NULL)
{
std::cout << "建立視窗失敗" << std::endl;
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
std::cout << "初始化GLAD失敗" << std::endl;
return -1;
}
while (!glfwWindowShouldClose(window)) {
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
return 0;
}
有彈出框代表成功！
另外
網上有一段程式碼需要的依賴庫是glaux.h，這裡需要宣告的是GLAUX（OpenGL輔助庫）所使用的函式和常量宣告。目前這個庫已經過時，只有比較少的編譯環境中有提供，例如VC系列。在這裡也給出相關配置：
下載連結：https://download.csdn.net/download/shengshengshiwo/10744364
1、將glaux.h 複製到 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\include\gl
2、將glaux.lib 複製到 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.15.26726\lib\x86
3、將glaux.dll 複製到 C:\Windows\System32 資料夾裡
4、輸入以下程式碼：

5、結果
總結
細心的朋友已經發現，其實配置OpenGL很簡單，小生在這裡總結一下。
- 下載所需依賴庫
- 將
.h檔案放到..\VC\Tools\MSVC\14.15.26726\include\gl資料夾裡； - 將
.lib檔案放到..\VC\Tools\MSVC\14.15.26726\lib\x86資料夾裡； - 將
.dll檔案放到C:\Windows\System32資料夾裡； - 將
.c檔案放到與原始碼同一目錄下； - 新建專案，引入
.h檔案即可！
