解决：

sudo apt-get install libcanberra-gtk-module

*如果已安装可以：

原来是指令有问题，查了一下mex file.cpp后面应该加上-l+库

>> mex ~/t/RenderMex.cpp -lGLU -lGL -lglut

OSMesa的函数无法引用，试了一下加一句-l

2018/12/8
新的一天已经出现，旧的error让我停滞不前
换在windows系统下跑matlab，但是始终找不到GL/xxx头文件
-l指令也找不到库

今天也没有查到解决办法呢
先放着8

mex -v -L. -lGLU -lGL -lglut ~/t/RenderMex.cpp
先dpkg -L libosmesa6-dev
输出：

将上面的文件夹通过set path->add folders...添加到路径
然后mex -v -L. -lGLU -lGL -lglut ~/t/RenderMex.cpp
