ILOG CPLEX Technologies

CPLEX comes in three forms to meet a wide range of users' needs:

The CPLEX Interactive Optimizer is an executable program that can read a problem interactively or from files in certain standard formats, solve the problem, and deliver the solution interactively or into text files. The program consists of the file cplex.exe on Windows platforms or cplex on UNIX platforms.
Concert Technology is a set of C++ and Java class libraries offering an API that includes modeling facilities to allow the programmer to embed CPLEX optimizers in C++ or Java applications. The library is provided in the files in the table below.

Table 1: Concert Technologies Class Libraries

MS Windows
Unix

C++
ilocplex.libconcert.lib
libilocplex.alibconcert.a

Java
cplex.jar
cplex.jar

: The Concert Technology libraries make use of the Callable Library (described next).

The CPLEX Callable Library is a C library that allows the programmer to embed CPLEX optimizers in applications written in C, Visual Basic, FORTRAN, or any other language that can call C functions.The library is provided in files cplex81.lib and cplex81.dll on Windows platforms, and in libcplex.a, libcplex81.so, and libcplex81.sl on UNIX platforms.

In this manual, the phrase "CPLEX Component Libraries" is used when referring equally to any of these libraries. While all of the libraries are callable, the term "CPLEX Callable Library" as used here refers specifically to the C library.

Compatible Platforms

ILOG CPLEX is available on Windows and UNIX platforms. The programming interface works the same way and provides the same facilities on all platforms.

Installation Requirements

If you have not yet installed ILOG CPLEX on your platform, please consult Chapter 1, Setting Up CPLEX. It contains instructions for installing ILOG CPLEX.
