OpenGL GLFW構建錯誤或鏈接錯誤

Question

有人可以幫助我讓GLFW在Visual Studio 2012中工作嗎？ 我無法通過最初的編譯。 對於GLFW功能，我一直都無法解決外部問題。 問題是，我不知道我在做什么錯。 我可以是：

• 用CMake錯誤地制作源文件。
• 圖書館建設不當。
• 鏈接到GLFW庫不正確。

我不確定是哪個，所以我只列出我做了什么：

1. Downloaded glfw-3.1.1 from glfw.org.
2. Used CMake GUI to make the source files.
    a. Set source code to C:/GLFW/glfw-3.1.1
    b. Set "Where to build the binaries" to C:/GLFW/glfw-3.1.1/GLFW_Built (I created that directory)
    c. Clicked "Configure" 
    d. Selected "Visual Studio 11 2012" as the generator (I also tried "Visual Studio 11 2012 Win64," but it gave me the same results. The ARM one wouldn't build at all)
    e. Left "Use default native compilers" selected.
    f. Clicked "Finish."
    g. Set "BUILD_SHARED_LIBS" to true (checked).
    h. Clicked "Generate."
3. Built the library.
    a. Went to C:\GLFW\glfw-3.1.1\GLFW_Built and opened GLFW.sln in Visual Studio 2012.
    b. Clicked BUILD->Build ALL_BUILD (worked fine, no errors)
4. Created a new blank project in Visual Studio 2012.
5. Went into the properties pages and set:
    a. Configuration Properties/VC++ Directories/Include Directories: added "C:\GLFW\glfw-3.1.1\include"
    b. Configuration Properties/VC++ Directories/Library Directories: added "C:\GLFW\glfw-3.1.1\GLFW_Built\CMakeFiles\Export\lib" (it was the only lib folder I saw) and "C:\GLFW\glfw-3.1.1\GLFW_Built\src\Debug" (contains glfw3.dll and glfw3dll.lib)
    c. Configuration Properties/C/C++/Additional Include Directories: added "C:\GLFW\glfw-3.1.1\include"
    d. Configuration Properties/Linker/General: added "C:\GLFW\glfw-3.1.1\GLFW_Built\src\Debug
    e. Configuration Properties/Linker/Input: added "glfw3dll.lib" and "opengl32.lib"

對於我的代碼，main.cpp中只有一個非常簡單的測試程序：

#include <GLFW/glfw3.h>
#include <thread>

int main()
{
    glfwInit();
    std::this_thread::sleep_for(std::chrono::seconds(1));
    glfwTerminate();
}

但是我總是在輸出中得到這個：

1>main.obj : error LNK2019: unresolved external symbol _glfwInit referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _glfwTerminate referenced in function _main
1>C:\Users\Adam\Desktop\Revenant\Revenant\Debug\Revenant.exe : fatal error LNK1120: 2 unresolved externals

將GLFW提取到C:\\glfw-src （以使存檔中的CMakeLists.txt位於C:\\glfw-src\\CMakeLists.txt ）

• cd C:\\glfw-src
• mkdir build
• cd build
• cmake-gui ../
• 按配置，選擇工具鏈
• 將CMAKE_INSTALL_PREFIX設置為C:/glfw
• 創建c:\\glfw目錄
• 再次按配置
• 按生成
• 在Visual Studio中打開build\\GLFW.sln
• 生成ALL_BUILD項目的發行版本
• 生成INSTALL項目的發行版本

C:\\glfw現在應該包含include和lib目錄。

假設采用全新的“空項目”解決方案：

• 編譯器：將c:\\glfw\\include添加到/I （配置屬性-> C / C ++->常規->其他包含目錄）
• 鏈接器：將c:\\glfw\\lib添加到/LIBPATH （配置屬性->鏈接器->常規->其他庫目錄），並將glfw3.lib和opengl32.lib添加到/DYNAMICBASE （配置屬性->鏈接器->輸入->其他依賴項）
