Hello,

 

I am trying to install CPLEX 12.8 on ubuntu 16.04. It is a brand new machine and CPLEX is the very first package I am installing on this.

 

I downloaded the .bin file, changed it to executable and gave the following command:

username@username-Inspiron-3268:~/Downloads$ ./cplex_studio128.linux-x86-64.bin

 

It goes through some initial steps but gets stuck at the following:

 

Where would you like to install?

 

Default intall folder:/opt/ibm/ILOG/CPLEX_Studio128

 

Enter an absolute path, or press <Enter> to accept the default

 

On pressing <Enter>, the system says:

 

"You do not have write permissions to the chosen installation destination. Please choose a different location for installation"

 

How should I go about installing the package now?

 

The IBM provided documentation provided 

 

http://www-01.ibm.com/support/docview.wss?uid=swg21444285

 

does not clarify.

 

Thanks in advance.

Never mind. I figured it out.

 

I am new to linux/ubuntu.

 

Got cplex installed by typing

 

sudo  ./cplex_studio128.linux-x86-64.bin

 

Thanks.

Another (and sometimes better) better option would have been to install to a non-default directory, especially if you don't have the privileges to do sudo. For example, installing to your home directory should never run into permission issues.
