内容导读
互联网集市收集整理的这篇技术教程文章主要介绍了c – opengl程序编译但运行时出错(UBUNTU 14.04)，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含24892字，纯文字阅读大概需要36分钟。
内容图文
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 Error of failed request: GLXBadFBConfig
Major opcode of failed request: 156 (GLX)
Minor opcode of failed request: 34 ()
Serial number of failed request: 42
Current serial number in output stream: 41
对此的输入
(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})
给出一个输出

解决方法:
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,则会发生这种情况.
更新：实际问题
现在您发布了代码,很容易看出问题所在：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(glxinfo也报告)：
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.0
但是,您的程序要求提供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.
在你的情况下,我打赌它是第一种情况：你的系统缺乏正确的驱动程序安装.
为了进一步帮助您,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})
