我跑http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=06網站的範例(在最下面有BCC的範例可下載)，可是執行時，出現下列訊息

 
[Linker Error] Unresolved external 'auxDIBImageLoadA' referenced from C:\LESSON06_BCB6\LESSON06.OBJ

(我把檔案解壓縮在C:下執行)我猜可能是auxDIBImageLoad出問題，最慘的是後面的範例都有此，如果沒有決解此問題，後面都不用做了~各位朋友知道有什麼問題嗎?

看看 BCB 底下有沒有 GlAux.lib 可能要把它加到 Porject 裡吧？ 手上沒有 BCB 沒辦法幫你試......

這程式我有玩過, 如果沒錯應該是(第六課)紋理對映Texture Mapping :     要點： 1. bmp檔大小至少64x64(2的倍數)，顏色至多256色 2. 載入Lib函式庫到專案：Project Add to Project? glaux.lib 3. glBindTexture()不可在glBegin()及glEnd()之間 4. 貼圖流程： GLuint id; AUX_RGBImageRec *txt = auxDIBImageLoad("*.bmp"); glGenTextures(圖片數, id) glBindTexture (GL_TEXTURE_2D, id); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER , GL_LINEAR); glTexImage2D (GL_TEXTURE_2D, 細節, 色分量數, 寬, 高, 邊界粗細, GL_RGB, GL_UNSIGNED_BYTE, 圖資料); 5. 貼圖解析度有三種：GL_NEAREST、GL_LINEAR、GL_LINEAR_MIPMAP_NEAREST。 (一)Unit1.h： GLfloat deg1, deg2, deg3; GLuint id[6]; (二)Unit1.cpp： void __fastcall TForm1::FormCreate(TObject *Sender) { myDc = GetDC( this->Handle ); PIXELFORMATDESCRIPTOR myPfd = { sizeof(PIXELFORMATDESCRIPTOR), 1, PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER, PFD_TYPE_RGBA, 24, 0,0, 0,0, 0,0, 0,0, 0, 0,0,0,0, 32, 0, 0, PFD_MAIN_PLANE, 0, 0,0,0 }; myPf = ChoosePixelFormat(myDc, &myPfd); SetPixelFormat(myDc, myPf, &myPfd); myRc = wglCreateContext( myDc ); wglMakeCurrent(myDc, myRc); ///// 載入材質 ///// AUX_RGBImageRec *tex0, *tex1, *tex2, *tex3, *tex4, *tex5;

感謝你們的說明哦~現在我是用書上附的OpneGL VCL，配合此網站的程式，所以沒有之前的問題了~感謝哦
