MATLAB 的 libGL 错误

当我从终端调用 matlab 时

libGL error: unable to load driver: r600_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r600
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

我的 libgl 驱动程序

我可以找到图书馆

milenko@milenko-desktop:~$ locate r600_dri.so
/usr/lib/x86_64-linux-gnu/dri/r600_dri.so

我已经建立了符号链接

 sudo ln -sf /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0 /usr/local/MATLAB/MATLAB_Production_Server/R2015a/sys/opengl/lib/glnxa64/libGL.so.1.5.070200

但

我应该尝试什么？我在使用 Ubuntu 16.04。

答案1

问题显然是由于驱动程序安装在两个文件夹中。我发现一个解决方案在官方 MATLAB 论坛上。

我通过重命名驱动程序文件解决了该问题：

cd MATLAB_ROOT/sys/os/glnxa64/
sudo mv libstdc++.so.6 libstdc++.so.6.old

答案2

您可以尝试以下命令来创建符号链接。

ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /opt/MATLAB/XXXXX(R2014b)/sys/os/glnxa64/libstdc++.so.6

答案3

我通过重命名驱动程序文件解决了该问题。

cd MATLAB/sys/os/glnxa64/
sudo mv libstdc++.so.6 libstdc++.so.6.old
