在Linux下设置CPLEX和Eclipse


for my own documentary and for those who need this.

Something Unrelated:

I used to use AMPL as my modeling language and solve the problem with CPLEX. However, later I realized that AMPL is just a modeling language, but not a generic programming language, which makes it incapable to handle my problem since I have to customize some parts of the algorithm. Then I started to use CONCERT from ILOG. At the same time, a “fancy friend” introduced me to use Python. I do not know for what reason I switched to LINUX, maybe because of the powerful command line. I got cplex set up, I got ampl set up and I got gcc set up, and then I need an IDE. I chose the popular one, eclipse. However, annoying things happened, I cannot compile my programs inside the IDE, while I can compile it with a self written make file. I need IDE because I want to make the debug easier. During that time, I need to reboot my computer many times to switch between windows and Linux, (I was thinking to use a virtual machine, but I did not do that). Fortunately, I got eclipse to work with cplex. It maybe not the best solution, but good enough to me, a newbie of Linux, programming, eclipse and cplex. :-) There was another story of installing Linux in my thinkpad T60, and make everything run smoothly.

Something Related:

OK, first thing is to install eclipse and CDT. There are lots of tutorials on this, so I will not cover this. Suppose you have CPLEX installed in the default directory: /usr/ilog/ . The setting is really nothing but putting the correct path into the correct place. As an old Chinese saying goes, a picture is better than thousands of words, I will put the screen shots below.

I wrote this post two years ago, and I was using cplex 10.0. I don’t have a chance to try the new versions yet.

@@ update Nov 23,2010:

Thanks Yuan provided the setting for CPLEX 12

    hi, I just move to linux and want to install ampl. get some problem now:
    I downloaded the AMPL for Linux from the main web,
    then
    sudo gzip -d ampl.gz
    sudo mv ampl /usr/bin/
    sudo chmod +x /usr/bin/ampl
    But if I run ampl, the system tell me that no such file or directory
    Using command “which ampl”, the directory is true.

    finally i find two ways to solve this,first is enter the full file name include the path; second is go to the direct typing ./ampl.

    Could you kindly tell me why it doesn’t work by just typing ampl. thanks very much.

    Hi, nosper

    The problem is you did not add the path of the ampl path to PATH variable. Try to run

    export PATH=$PATH:/path/to/AMPL/directory

    Another way is make a link of the ampl file into the /usr/bin rather than coping the ampl file to that directory.

    @Yuan,
    Thanks. I think I saw you in INFORMS. I was president of INFORMS student Chapter at ASU.
