The AMPL API can function as an add-on to any existing AMPL installation. If you do not yet have an AMPL installation on the computer where you will be working with the API, see our demo page or trial page to download a working version that can be installed quickly.
Follow the instructions on our AMPL API
page to download the API package appropriate to your platform, and to add
the downloaded folder (directory)
amplapi to your AMPL installation.
AMPL API includes a CMake script that can be used to build C++ examples on a
wide range of platforms. To begin, download
and install the free CMake utility. Open a command/terminal window, make
amplapi/examples/cpp the current folder (directory), and invoke
to generate native makefiles or project files that can be used in the compiler environment of your choice:
- Under Linux or any Unix-like environment, you will see a Makefile in the current directory; you can then build examples by running make.
- Under Windows with Visual Studio installed, the
EXAMPLES.slnfile and several project files will be created. You can then build examples using Visual Studio or MSBuild.
- Under Mac OS X with Xcode installed, an
.xcodeprojfile will be generated and can be used to build the examples.
To complete an initial test, build
firstexample using these generated
files, and then invoke it with
<solver> is the name of a solver that has been installed with AMPL.
(If a solver is not specified, AMPL’s default choice will be used.) This will solve
several small diet problems and then display the optimal amounts of the foods
from the last solution.
ampl/ampl.h header from the
amplapi/include folder (directory)
in your C++ code and link binaries with the AMPL library (
libampl.so on Linux,
libampl.dylib on OS X,
ampl1.2.2.lib on Windows) from
amplapi/lib to use the AMPL API. Together with your existing AMPL
implementation, this will provide the full object library and access to all
amplapi folder (directory) can be moved to a different location in
your computer’s filesystem, provided that the location of your AMPL executable
has been placed in the system search path.
To deploy AMPL API applications to users who do not have their own AMPL installations,
include with your C++ application the AMPL
ampl.exe); the shared library (
lib/libampl.so.1.2.2 on Linux,
lib/libampl.1.2.2.dylib on OS X,
bin/ampl1.2.2.dll on Windows)
which contains the full implementation of the C++ object library; binaries
needed to run any solvers that are used; and an appropriate license
file for AMPL and solvers.
