使用CodeBlocks將GLEW鏈接到SFML項目中的問題

Question

因此，我正在學習編寫着色器並將它們合併到我的OpenGL程序中（我使用SFML 1.6來創建有效的OpenGL環境，而不是用GLUT來分解;我的IDE是Codeblocks ;我的卡支持OpenGL 3.1和GLSL 1.3）。不過，我已經遇到了麻煩。看起來我需要GLEW來幫助將GLSL着色器合併到我的程序中。所以我去了GLEW的源代碼，並使用CodeBlocks將其編譯爲靜態庫，按照最終評論here（我在文件中添加了#define GLEW_STATIC）的說明，因爲我不清楚我應該在哪裏添加它），所以我現在有四個.a文件：

libglew32.a，libglew32d.a，libglew32mx.a，libglew32mxd.a

我已經告訴我的編譯器在哪裏找頭文件（glew.h，glxew.h，wglew.h），並且我已經通過將相關目錄添加到Settings-> Compiler & Debugger ...->中告訴鏈接器在哪裏找到庫（上面）搜索目錄。在我的項目中，在Build Options-> Linker Settings-> Link Libraries下，我還鏈接了上述四個。

做上述所有的，我想glewInit調用（）時出現以下錯誤：

未定義的引用「_imp__glewInit」

一些reading告訴我，我需要添加#define GLEW_STATIC之前#include <glew.h>，所以我做到了，現在我得到了一個未定義的參考「wglGetProcAddress @ 4」錯誤（我的程序中唯一的GLEW代碼行是glewInit();）：

我不知所措;所有這些（鏈接/編譯/等等）的技術方面對我來說仍然是新的和令人困惑的。

爲了讓GLEW能夠工作，我需要做些什麼才能將GLSL着色器合併到我的SFML OpenGL項目中？ （或者我可以在沒有GLEW或任何其他外部庫的情況下以某種方式更容易地執行此操作？這將會非常棒！）

您還需要鏈接opengl32.lib。缺少鏈接器的這些函數會引起opengl32.dll的一部分，並且需要鏈接它才能訪問它。不在靜態庫中，而在最終的程序中。從技術上講，靜態庫不是別的，就像對象文件的存檔一樣，即編譯階段的結果。鏈接到DLL需要在可執行二進制文件的上下文中發生。
