Difference between OpenGL files glew.h and gl.h/glu.h

由 蓝咒 提交于 2019-11-27 09:53:17
问题 I've built an OpenGL program with my glu and gl header files default included in windows 7 professional edition. Now, I've bought a book that describes OpenGL game development. The author of this book said, I have to include the glew header into my project. After I've done this I got some unresolved external symbol errors. So, now I'm really confused. I've worked earlier with glBegin and glEnd statements in my program. Now I've to work with glBindBuffers and glGenBuffer etcetera, but I get

Undefined reference to `_imp__glewInit@0'

问题 I have built the glew lib so many times. My last build removed the undefined references to all the shader functions such as glCreateShader() . I think this build is the correct one cause I found out that Code:Blocks can open Visual Studio 6.0 projects so it had everything laid out for me. I can compile my app without calling glewInit() but it results in a SEGFAULT right when glCreateShader() is called. Which is caused by not Initializing glew. I need to turn it on but it wont let me XD links:

Using GLEW to use OpenGL extensions under Windows

由 落花浮王杯 提交于 2019-11-27 03:31:54
I've been using OpenGL extensions on Windows the painful way . Is GLEW the easier way to go? How do I get started with it? Yes, the OpenGL Extension Wrangler Library (GLEW) is a painless way to use OpenGL extensions on Windows. Here's how to get started on it: Identify the OpenGL extension and the extension APIs you wish to use. OpenGL extensions are listed in the OpenGL Extension Registry . Check if your graphic card supports the extensions you wish to use. Download and install the latest drivers and SDKs for your graphics card. Recent versions of NVIDIA OpenGL SDK ship with GLEW. If you're

问题 It is a duplicate and I am sorry about it but I don't have any other options because I can't make comments on answers and they didn't solved my problem. Here is the original post: Building glew on windows with mingw And here is my problem: 1) When I try @LightningIsMyName's answer I get this error: Makefile:1: *** missing seperator. Stop. 2) When I try @anon's answer I get this error: Makefile:1: Makefile:1: *** commands commence before first target. Stop. People says this andswer helped them

问题 Hi I have problem with linkg Glfw and other libraries using cmake. From command line i compile like this g++ main.cpp -lGL -lGLU -lGLEW -lglfw But I wanted to use cmake for compiling. I tried to use target_linkg_libraries but this produce error CMake Error at CMakeLists.txt:18 (target_link_libraries): Cannot specify link libraries for target "GL" which is not built by this project. I tried do this using add definitions. I dont see error but this don't link libraries. cmake_minimum_required

GLEW Linker Errors (undefined reference to `__glewBindVertexArray')

由 半世苍凉 提交于 2019-11-26 23:40:33
问题 I've recently made the decision to re-write some OpenGL code for a game using im working on using non depreciated techniques. Instead of drawing primitives with glBegin() and glEnd(), i'm trying to stick to vertex array objects and such. I'm trying to get code to compile from http://www.opengl-tutorial.org/beginners-tutorials/tutorial-2-the-first-triangle/ . I've done alot of linking before but for some reason this isn't working. I'm trying to link GLEW to my project with CodeBlocks as my IDE

OpenGL: glGetError() returns invalid enum after call to glewInit()

由 笑着哭i 提交于 2019-11-26 18:28:18
问题 I use GLEW and freeglut. For some reason, after a call to glewInit(), glGetError() returns error code 1280, even with glewExperimental = GL_FALSE. I cannot compile the shaders, glGetProgramInfoLog() returns "Vertex shader(s) were not successfully compiled before glLinkProgram() was called. Link failed." I was able to compile the shaders before. Reinstalling the drivers didn't help. Here's my code: int main(int argc, char* argv[]) { GLenum GlewInitResult, res; InitWindow(argc, argv); res =

Linking GLEW with CMake

由 不想你离开。 提交于 2019-11-26 18:25:47
问题 How can you link GLEW to a project with CMake? We've been trying to link GLEW to our project using CMake for at least 3 hours without any success so any help is accepted. I'm using the FindGLEW.cmake which comes with CMake 3.1.0 CMakeLists.txt find_package(GLEW REQUIRED) if (GLEW_FOUND) include_directories($(GLEW_INCLUDE_DIRS)) endif() Environment Variables I'm using MinGW w64 to compile the sources and we successfully linked GLFW and GLM just by copying the includes and libs to their

Why does glGetString(GL_VERSION) return null / zero instead of the OpenGL version?

由 瘦欲@ 提交于 2019-11-26 16:41:26
问题 I'm on Linux Mint 13 XFCE. My problem is that when I run in terminal the command: glxinfo | grep "OpenGL version" I get the following output: OpenGL version string: 3.3.0 NVIDIA 295.40 But when I run the glGetString(GL_VERSION) in my application then the result is null. Why doesn't this code get the gl_version ? #include <stdio.h> #include <GL/glew.h> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> #include <GL/glext.h> int main(int argc, char **argv) { glutInit(&argc, argv);

Building glew on windows with mingw

由 末鹿安然 提交于 2019-11-26 16:04:14
Can anyone give me the correct command to build glew on windows with mingw? I have tried: gcc -static glew.c glewinfo.c visualinfo.c -I/path/to/glew/include but I am getting thousands of linker errors (missing reference). I can't build with Make because unfortunately the makefile has lots of unix only commands and i don't have cygwin or anything at work. (alternatively if anyone can point me to a windows 32b build i would be very grateful) To build it with MinGW, you should do (copied from the make log, with slight modifications and additional explanations): mkdir lib/ mkdir bin/ gcc -DGLEW_NO
