The error indicates that libgtk-x11-2.0.so.0 cannot be found. Please make sure that you have GTK libraries installed on your machine. For example, in Ubuntu you can find a package providing libgtk-x11-2.0.so.0 with the apt-file command:

  > apt-file find libgtk-x11-2.0.so.0

  libgtk2.0-0: /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0

HTH,

Victor

The error message that you see (in the attached screenshot) is common; it appears when you have downloaded the AMPL IDE but it has not been installed in the right place. You will need to first locate your "AMPL folder", which is the one that contains "ampl.exe" (Windows) or the executable file "ampl" (Linux or MacOSX). Then place the folder named amplide -- which you got by following the instructions at www.ampl.com/IDE -- inside your "AMPL folder". After you have done this you can go inside the amplide folder and start the amplide application (Windows or Linux) or just double-click the amplide icon (MacOSX).

Complete instructions are given at http://ampl.com/products/ide/. This has fixed the problem in every case so far, but if you continue to have difficulties, let us know what platform you are using (Windows, Linux, or MacOSX) and where you downloaded your AMPL folder from. Also again send us a complete copy of the error messages you are getting.

Dear Mr Robert Fourer,

The error was fixed, it's exactly as you describe: The  AMPL IDE was not  installed in the right place + the executable file was not in the AMPL folder as well, i thought that the AMPL IDE contain it all as a full package.

Thanks a million for your precious help sir.

Have a good day!
