gl linux qt 库

gl linux qt 库

我正在运行64位Ubuntu 14.04。

我得到的编译错误是：

In file included from ../../../Qt/5.4/gcc_64/include/QtOpenGL/qgl.h:39:0,

from ../../../Qt/5.4/gcc_64/include/QtOpenGL/qglshaderprogram.h:37,

from ../../../Qt/5.4/gcc_64/include/QtOpenGL/QGLShaderProgram:1,

from glwidget.h:5,

from glwidget.cpp:1:

../../../Qt/5.4/gcc_64/include/QtGui/qopengl.h:122:21: fatal error: GL/gl.h: No such file or directory

# include

^

奇怪的是，我似乎已经正确安装了libGL.so并将其符号链接到我的Nvidia 343显示驱动程序(我想还安装了OpenGL驱动程序)所安装的OpenGL库中。

$ ls -l /usr/lib | grep -i libgl

我以前看过一些建议做的事

sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

但是当我尝试这样做时，它将我支持的OpenGL版本(由glxinfo输出)降级为v1.4。另外，我不确定为什么应该有所帮助。

这是我的glxinfo输出。

$ glxinfo | grep -i opengl
