谢谢两位。我的安装源就是一个安装目录（/MATLAB INSTALL），在home里，从硬盘安装。参考了下面帖子
viewtopic.php?t=75503&highlight=matlab+ ... 9%E8%A3%85
我在home下建了Matlab目录，把lisence_locked.dat拷贝到Matlab目录里并改名成lisence.dat。安装目录下运行./install 提示出错如下：
An error status was returned by the program 'xsetup',
the X Window System version of 'install'. The following
messages were written to standard error:
/home/yu/MATLAB INSTALL/update/install/main.sh: 168: /home/yu/MATLAB INSTALL/update/bin/glnx86/xsetup: Permission denied
Attempt to fix the problem and try again. If X is not available
or 'xsetup' cannot be made to work then try the terminal
version of 'install' using the command:
install* -t or INSTALL* -t
-------------------------------------------------------------------
Sorry! Setup aborted . . .
glnx86 目录下的 xsetup是干什么的？ 这个错误是什么意思？ 请指教，谢谢。
