glew

I have code from the OpenGLBook (openglbook.com) which compiles, but does not load. I have absolutely no idea why it's not loading. The code is as follows: main.cpp #include "main.h" /// Methods /// ----------------------------- int main(int argc, char* argv[]) { Initialize(argc, argv); glutMainLoop(); exit(EXIT_SUCCESS); } main.h #ifndef main_h #define main_h #include <cstdlib> #include <cstdio> #include <cstring> #include <GL/glew.h> #include <GL/freeglut.h> #define WINDOW_TITLE_PREFIX "CHAPTER 1" void Initialize(int, char*[]); void InitWindow(int, char*[]); void ResizeFunction(int, int);

I'm wanting to get into and learn OpenGL in C++ and am using Code::Blocks. I was able to get freeglut to work, along with several online examples (as well as the example that ships with CB). However, when I try to include GLEW for some tutorials I'm following, I get the following compiler errors: obj\Debug\main.o||In function `RenderSceneCB':| C:\C Programs\OpenGL Test\main.cpp|12|undefined reference to `_imp____glewEnableVertexAttribArray'| C:\C Programs\OpenGL Test\main.cpp|13|undefined reference to `_imp____glewBindBuffer'| C:\C Programs\OpenGL Test\main.cpp|14|undefined reference to `_imp_

So I started using OpenGL with glew and GLFW to create a game engine, and I almost immediately ran into a problem when starting working with shaders: They are not being used or have no effect whatsoever if they are being used. I have been checking my code with plenty of other examples, and they all match up, nothing looks out of place, and I am starting to run out of ideas and patience (I have been trying to figure out why for nearly a month now) with this. My main core code is here: #include "headers/Default.hpp" //Window width and height variables int windowWidth = 800; int windowHeight =

I'm trying to use VBO in my OpenGL project. I'm using glew library for extensions and glfw for windows handling. When I try to create VBO application crashes and I get Unhandled exception at 0x00000000 in symulator3C.exe: 0xC0000005: Access violation in function glGenBuffersARB. Here's my code: GLuint vboId1=0; //this is global variable void createVBO(){ normalsVBO = (float *) malloc(sizeof(float)*3*(SIZE_X-1)*SIZE_Y*2); verticesVBO = (float *) malloc(sizeof(float)*3*(SIZE_X-1)*SIZE_Y*2); if(normalsVBO==NULL) exit(-1); if(verticesVBO==NULL) exit(-1); glGenBuffersARB(1, &vboId1); //HERE IT

I can't link properly to glew. I have done: #define GLEW_STATIC #include "glew/glew.h" #pragma comment(lib, "glew/glew32s.lib") However, I still get the error: LNK2019: unresolved external symbol __glewGenBuffersARB referenced in function initialize Save yourself a lot of trouble and just put the glew.c file into your project. I never bother with linking to a glew library externally. Once you have that in there, the GLEW_STATIC macro will work. It's only one file, and (if this matters to you) it will carry nicely across platforms (rather than having to rebuild several OS-specific libs). 来源：

I am having issues compiling a basic openGL program on VS 2012. I get a build error upon compiltation giving me: 1>LINK : fatal error LNK1104: cannot open file 'glew32.lib' I followed the instructions given to me by the documentation for GLEW. In your OpenGL project open Project -> Properties -> Configuration Properties -> Linker -> Input -> Additional Dependencies -> add glew32.lib. Also you must include #include in your sources; For that add path to your glew folder: Project -> Properties -> Configuration Properies -> General -> VC++ Directories -> Include Directories and Library Directories

I download the glew source file from http://glew.sourceforge.net/ . In the readme file, it says I should use \build\vc6.0\glew.dsw to comple the DLL. But there are four projects after I open it in VS 2010. When I compile them, 2 of them failed to compile. Thanks. Just a guess but by the way that folder is labelled, it's probably meant to compile using Visual C++ 6.0, which came with Visual Studio 6. I just gave it a quick try and built without problems under that IDE. Of course, I don't believe Microsoft offers that product anymore. If you want to build it yourself, you'll probably have to
