glew

问题 My problem is the glDrawArray command stops working. I've written a few programs which I used that command. However now, I don't have any idea why it doesn't work. But I still can draw lines to the screen with GL_LINES instead of GL_TRIANGLES . Here is my code: #include "Mesh.h" #include <iostream> Mesh::Mesh() { glGenVertexArrays(1, &vao); glBindVertexArray(vao); glGenBuffers(1, &vbo); size = 0; } void Mesh::AddVertices(const Vertex vertices[], int length) { size = length; glBindBuffer(GL

问题 When I read the instructions I am confused since it says in the instructions to install glew at <VC_ROOT>\include\GL\glew.h and then it says on windows to #include <glew.h> and not #include <GL/glew.h> and I don't know whether this should be before or after #include <GL/glut.h> . I can build the freeglut example so glut appears to be correctly installed and my problem seems to be with building with glew. The complete program that I try to run is // Two-Dimensional Sierpinski Gasket //

问题 I'm new to OpenGL and try to learn OpenGL 4 by following the http://www.openglbook.com tutorial. On page two, we create a simple triangle using shaders. But right after creating the vertex shader, the program crashes. By Debugging, I could find a OpenGL error GL_INVALID_ENUM (0x0500). See code below... Unfrotunately I couldn't find any solution. Maybe you know sth? Edit: So, after searching again for GL_INVALID_ENUM and glewInit() , I found that there are already many posts on other Websites,

问题 When I'm trying to build and run my OpenGL+GLEW+GLFW program, it builds just fine but wont run, giving me this error : "The program can't start because glew32.dll is missing from your computer. Try reinstalling the program to fix this problem." I am linking glew32.lib as a static library. I am also using #define GLEW_STATIC . Then, why is the program prompting for a DLL file? #include <iostream> //#define GLEW_STATIC // GLEW #include <include/GL/glew.h> // GLFW #include <include/GLFW/glfw3.h>

问题 I installed glew, glfw and glm in eclipse cdt(c++) with the gcc/mingw, all statically. All works fine, but I don't like the warning in the output console of eclipse: Warning: corrupt .drectve at end of def file How I can fix and hide this warning ? What does it mean ? And what I noticed is, that this warning comes only, if I call the 'glewInit' function. 回答1: When I ran into this problem it was because I was linking against incompatible MSVC libs. A comment by keltar helped me through this
