Using Windows 7 Home Premium 64bit with Visual Studio 2010 Professional on HP Pavilion g6. Code is written in C/C++.

在HP Pavilion g6上使用Windows 7 Home Premium 64位和Visual Studio 2010 Professional。代碼是用C / C ++編寫的。

Reported Errors:

glut.h:
First-chance exception at 0x00000000 in gl_crap3.exe: 0xC0000005: Access violation.
Unhandled exception at 0x76fe15de in gl_crap3.exe: 0xC0000005: Access violation.
Error occurs on line 486 - static void APIENTRY glutInit_ATEXIT_HACK(int *argcp, char **argv) { __glutInitWithExit(argcp, argv, exit); }

Other Noticed Symptoms:

其他注意到的症狀:

• Crash alternates between osfinfo.c, dbgheap.c and mlock.c when printf command ISN'T commented out

當printf命令未被注釋掉時,崩潰在osfinfo.c,dbgheap.c和mlock.c之間交替

• Only crashes on glut.h when printf IS commented out

當printf IS被注釋掉時,只會在glut.h上崩潰

• When glGenBuffers is commented out, there are no unhandled exception errors - the program does not crash

當glGenBuffers被注釋掉時,沒有未處理的異常錯誤 - 程序不會崩潰

• Output of printf statement is: My OpenGL version is (null) - occurs irrespective of whether the program crashes or not

printf語句的輸出是:我的OpenGL版本是(null) - 無論程序是否崩潰都會發生

I'm completely stumped on this one, there appears to be literally nothing on the internet to help me out. I even focused on trying to solve the "OpenGL version = null" problem first, but I came out empty handed as I either followed the advice on this website incorrectly (not having a good enough understanding about OpenGL rendering contexts) or that problem is a symptom of the 0xC0000005 error.

我對這一點感到很難過,互聯網上幾乎沒有任何東西可以幫助我。我甚至專注於嘗試首先解決“OpenGL version = null”問題,但我空出來了,因為我要么錯誤地遵循了這個網站上的建議(對OpenGL渲染上下文沒有足夠的理解),或者問題是0xC0000005錯誤的症狀。

EDIT: As this problem seems to be caused by multiple problems I have decided to put an updated version of my code and the corresponding error I am getting from it. Thank you for helping me so far, but glGenBuffers just seems to hold a grudge on me or something.

編輯:由於這個問題似乎是由多個問題引起的,我決定把我的代碼的更新版本和我得到的相應錯誤。感謝你幫助我到目前為止,但glGenBuffers似乎只是對我或某事抱怨。

GLenum err = glewInit();
if (err != GLEW_OK) {
    string error = "GLEW extension loading failed: "+string((char*)glewGetErrorString(err));
    printf("%s\n",error); getchar();
}
