问题 I'm using Eclipse, MinGW, and I have compiled freeglut and glew and copied their libraries, DLLs, and header files into the proper locations (MinGW/include/GL, MinGW/lib, Windows/SysWOW64). I have also linked the libraries (freeglut64, opengl32, glew32, glu32) in Eclipse under the MinGW C++ Linker. Here is my code... --CharGame.cpp-- #include <stdlib.h> #include <stdio.h> #include <string.h> #include <GL/glew.h> #include <GL/freeglut.h> #include "CharGame.h" #define WINDOW_TITLE "CharGame"

Freeglut glew glutIdleFunc cause lag

问题 I'm just starting out with freeglut and glew and getting it running was already quite hard for me. So now I started coding with tutorials from swiftless and I had a square displayed worked fine. Now I got to the point where I want to make the square move with the arrow keys. From the point I inserted the glutIdleFunc it started lagging. I cant move the window or click on anything else for about a minute. If I try draging the window then it moves after about 2 min. I tried doing this with the

GLEW - why should I define GLEW_STATIC?

问题 I am using a statically linked library for GLEW and therefore I have to define GLEW_STATIC to compile my programs that are using GLEW. But I have never understood why this is necessary. So could anyone explain the reason? 回答1: The signature of a function which is exported by or imported from a static library is marked by the keyword export. A function which is imported from a dynamic library has to be marked by extern __declspec(dllimport). GLEW_STATIC is a preprocessor definition which

问题 I have been having this problem for a while and I cant for the love of me find a solution. I want to render a simple triangle. But i keep getting this output in visual studio when compiling the program. NOTE> I do not belive it is not a linking problem but something else. I have checked my linker countless times and everything is there! LINK: https://pastebin.com/xeTDd0Qu main static const GLfloat g_vertex_buffer_data[] = { 100.0f, 100.0f, 0.0f, 150.0f, 100.0f, 0.0f, 100.0f, 150.0f, 0.0f, };

Glew initialisation failed : Missing GL version (GLFW)

问题 I'm currently trying to draw a simple triangle with GLFW and GLEW. I'm using CLion (which is itself using cmake with cygwin) on a Win 8.1 x64 PC. My problem is : glewInit() returns error 1 ( Missing GL version ) when initialized. People (like in this thread) had a problem related to the OpenGL context, but mine is already created before I call glewInit() . Here is my code : #include <iostream> #include <stdlib.h> #include <vector> #define GLEW_STATIC #include <GL/glew.h> #include <GLFW/glfw3

问题 The program following, is one that creates a window which does nothing except close when you press esc. When I compile it with cygwin, there are no errors. The GLEW I use is from Cygwin Ports, and the SDL2 is version 2.0.3, from their website's SDL2-devel-2.0.3-mingw.tar.gz download. I have SDL2.dll in the directory of the compiled executable. Links with: -lSDL2 -lSDL2main -lGLEW -lGLU -lGL -lSDL2 -lSDL2main -lGLEW -lGLU -lGL , twice to ensure everything is linked. Also compiled with: -std=c+

问题 The following error occurred during runtime: The procedure entry point _ZSt24__throw_out_of_range_fmtPKcz could not be located in the dynamic link library "test.exe". I used a C++ demangler to find out which function is causing the entry point error. The function is: std::__throw_out_of_range_fmt(char const*, ...) I am linking to the following libraries: SDL2 (Dynamic, compiled from source by myself, same version of GCC that I'm using for my project (4.9.3)). GLEW (Added source to project) I
