Texture Mapping Error

My first post on the boards, and I would like to thank NeHe for his wonderful OpenGL tutorials. I am currently on lesson 6, but have hit a brick wall with the code. I am using MSVC++ 4.0 (yes, an older version, but I had it around and don't want to upgrade). The errors deal specifically with the glGenTextures and glBindTexture, which MSVC says are undeclared and do not evaluate to a function. Here are the errors: --------------------Configuration: 3d Cube Texture Map - Win32 Debug-------------------- Compiling... texture_test.cpp C:\Msdev\Projects\3d Cube Texture Map\texture_test.cpp(54) : error C2065: 'glGenTextures' : undeclared identifier C:\Msdev\Projects\3d Cube Texture Map\texture_test.cpp(54) : error C2064: term does not evaluate to a function C:\Msdev\Projects\3d Cube Texture Map\texture_test.cpp(57) : error C2065: 'glBindTexture' : undeclared identifier C:\Msdev\Projects\3d Cube Texture Map\texture_test.cpp(57) : error C2064: term does not evaluate to a function C:\Msdev\Projects\3d Cube Texture Map\texture_test.cpp(123) : error C2064: term does not evaluate to a function Error executing cl.exe. 3d Cube Texture Map.exe - 5 error(s), 0 warning(s) In case some of you aren't familiar with lesson 6, here is the LoadGLTextures() function: int LoadGLTextures() // Load Bitmaps And Convert To Textures { int Status=FALSE; // Status Indicator AUX_RGBImageRec *TextureImage[1]; // Create Storage Space For The Texture memset(TextureImage,0,sizeof(void *)*1); // Set The Pointer To NULL // Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit if (TextureImage[0]=LoadBMP("Data/NeHe.bmp")) { Status=TRUE; // Set The Status To TRUE glGenTextures(1, &texture[0]); // Create The Texture // Typical Texture Generation Using Data From The Bitmap glBindTexture(GL_TEXTURE_2D, texture[0]); // Generate The Texture glTexImage2D(GL_TEXTURE_2D, 0, 3, TextureImage[0]->sizeX, TextureImage[0]->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[0]->data); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); // Linear Filtering glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); // Linear Filtering } if (TextureImage[0]) // If Texture Exists { if (TextureImage[0]->data) // If Texture Image Exists { free(TextureImage[0]->data); // Free The Texture Image Memory } free(TextureImage[0]); // Free The Image Structure } return Status; // Return The Status } Thanks for any help you can provide, Dan [edited by - Erunama on April 17, 2002 6:26:45 PM]
