Hi, I am new to Cplex. I code my optimization problem on mac OSX 10.8, using Xcode 4.6 (c++).

Now I meet a problem:  when the size of the input is large, the program stops due to lack of license. (up to 500 variables and 500 constraints)

I use it for academic purpose. I search in google and find https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014494807 , I try the way they said, not work!

I put the access.ilm in /Users/mingliu/ILOG/ilm/, and then create a ".bash_profile" written "export ILOG_LICENSE_FILE=/Users/mingliu/ILOG/ilm/access.ilm". I click the exec file "~/ILOG/cplex/bin/86-64_darwin/cplex ", still no license.

BTW, another way they mentioned is http://www-stat.wharton.upenn.edu/~josezubi/INSTALL , but still not work!

I ready do not know how to make it? Could you please help me? Thanks in advance!

It looks like your license key is setup correctly and works as expected. But since that is a preview license the size of problems that can be solved with it is limited.

If you want to use CPLEX only for academic purposes then you can join the academic initiative. See for example http://www-03.ibm.com/ibm/university/academic/pub/page/ban_ilog_programming (there is a "join now" link on that page). If you are a member of the academic initiative you can get a copy of CPLEX that does not require a license key and does not limit the size of the problems it can solve.

Thanks very much for your kind reply!

I got the academic version, and  slightly modified the build settings in Xcode (caz the lib paths used here differ). Now it works very well!

You will have to get the license key from the official website. Or get the academic initiative version. This does not require a license key.
