复制 libgcc.so到指定目录。。。

sudo ln -s libstdc++.so.6 libstdc++.so

chmod 777 /usr/lib/gcc
sudo rm -rf /usr/lib/gcc

chmod 777 /usr/bin/X11/gcc
sudo rm -rf /usr/bin/X11/gcc

chmod 777 /usr/share/man/man1/gcc.1.gz
sudo rm -rf /usr/share/man/man1/gcc.1.gz

编译内核模块

1. cd out/linux.amd64/release/bin/src
2. make
3. make install
4. modprobe vboxdrv

    

   复制  /opt/VirtualBox-5.0.22/out/linux.amd64/release/bin 下的所有文件到

   到 /opt/VirtualBox

   然后点击 VirtualBox运行就行。

    

   软链接不行。。。

   ln -sf /opt/VirtualBox-5.0.22/out/linux.amd64/release/bin/* /opt/VirtualBox/
