opengl程序编译但运行时出错(UBUNTU 14.04)

时间:2014-05-24 12:04:39

标签: c++ opengl ubuntu mesa

我通过Synaptics Package manager安装了以下软件包来编译Opengl。

freeglut3 freeglut3-dev freeglut3-dbg libglew1.5 libglew1.5-dev libglu1-mesa libglu1-mesa-dev libgl1-mesa-glx libgl1-mesa-dev

这是我运行程序时的输出。

  

X请求失败的错误:GLXBadFBConfig

     

失败请求的主要操作码:156(GLX)

     

失败请求的次要操作码:34()

     

失败请求的序列号:42

     

输出流中的当前序列号:41


的输入
(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})

给出了

答案 0 :(得分:8)

错误代码GLXBadFBConfig表示系统的显示系统(X11服务器+图形驱​​动程序)不支持程序请求的像素格式。如果没有安装OpenGL支持的驱动程序,或者请求的FBConfig超出了GPU的功能,就会发生这种情况。

更新:实际问题

现在您发布了代码,很容易看出问题出在哪里:您的系统使用Xorg / DRI / Mesa项目的开源radeon驱动程序。这些驱动程序仅支持OpenGL-3.3(这也由glxinfo报告):

OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.0

但是你的程序要求提供OpenGL-4.3上下文

glutInitContextVersion(4, 3);
glutInitContextProfile(GLUT_CORE_PROFILE);

这是您的系统无法满足的请求。因此,你没有得到理想的FBConfig。

请注意,到目前为止,您的程序仅使用OpenGL-3.3中也提供的功能,因此我建议您只需在程序中询问3.3上下文。


在您的情况下,我是第一种情况下打赌:您的系统缺少正确的驱动程序安装。

为了进一步为您提供帮助,请将以下命令的输出添加到您的问题中:

(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})
