opengl - X失败的请求: BadMatch错误

Question

我正在尝试执行一些“hello world” opengl代码:

#include <GL/freeglut.h>

void displayCall() {
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glEnable(GL_DEPTH_TEST);
    ... Some more code here
    glutSwapBuffers();
} 

int main(int argc, char *argv[]) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(500, 500);
    glutInitWindowPosition(300, 200);
    glutInitContextVersion(4, 2);
    glutInitContextFlags(GLUT_FORWARD_COMPATIBLE);
    glutCreateWindow("Hello World!");
    glutDisplayFunc(displayCall);
    glutMainLoop();
    return 0;
}

结果，我得到:

  X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  128 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  39
  Current serial number in output stream:  40

这是堆栈跟踪:

fghCreateNewContext() at freeglut_window.c:737 0x7ffff7bbaa81   
fgOpenWindow() at freeglut_window.c:878 0x7ffff7bbb2fb  
fgCreateWindow() at freeglut_structure.c:106 0x7ffff7bb9d86 
glutCreateWindow() at freeglut_window.c:1,183 0x7ffff7bbb4f2    
main() at AlphaTest.cpp:51 0x4007df 

这是该程序崩溃后的最后一段代码:

createContextAttribs = 
  (CreateContextAttribsProc) fghGetProcAddress("glXCreateContextAttribsARB" );
if ( createContextAttribs == NULL ) {
    fgError( "glXCreateContextAttribsARB not found" );
}
context = createContextAttribs( dpy, config, share_list, direct, attributes );

已成功获取“glXCreateContextAttribsARB”地址，但是程序在调用时崩溃。

如果我在“glutInitContextVersion()”中指定小于4.2的OpenGL版本，程序将运行而不会出现错误。

这是我的glxinfo的OpelGL版本:

OpenGL version string: 4.2.0 NVIDIA 285.05.09

我将不胜感激任何进一步的想法。

Answer 1

我想我也有类似的问题。

如果我指定3.3，它将加载并显示

OpenGL Version: 3.3.0 NVIDIA 280.10.01.04

另一方面，如果我尝试4.0，则会看到此错误:

X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  135 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  39
  Current serial number in output stream:  40

我尝试更新驱动程序，但后来我意识到我的图形卡不支持OpenGL 4。

因此，我尝试回答另一个问题:您确定您的卡支持4.2吗？
