For enquiries about using Knitro on unsupported platforms, please contact Artelys.

Listed below are the C/C++ compilers used to build Knitro, and the Java and Fortran compilers used to test programmatic interfaces. It is usually not difficult for Artelys to compile Knitro in a different environment. From the 11.1 release, Knitro is compiled with the Intel compilers on most platforms. Contact us if your application requires special compilation of Knitro.

Instructions for installing the Knitro package on supported platforms are given below. After installing, view the INSTALL.txt, LICENSE_KNITRO.txt, and README.txt files, then test the installation by running one of the examples provided with the distribution.

The Knitro product contains example interfaces written in various programming languages under the directory examples. Each example consists of a main driver program coded in the given language that defines an optimization problem and invokes Knitro to solve it. Examples also contain a makefile illustrating how to link the Knitro library with the target language driver program.
