[Symphony] Symphony and AMPL in a Dockerfile

[Patrick Wieschollek]

Hi,

I hope this is the correct way to get in contact.

The documentation does not cover how to use symphony to solve models from
AMPL, although there are some flags to call symphony with a AMPL model file.

To make the problem reproducible I created a docker-image:
https://github.com/PatWie/symphony-docker

which contains all steps from
http://www.coin-or.org/SYMPHONY/man-5.1/node19.html

(See https://github.com/PatWie/symphony-docker/blob/master/image/Dockerfile)

However, I have the issue when calling
"/var/symphony/bin/symphony -F /var/symphony/SYMPHONY/Datasets/sample.mod
-D /var/symphony/SYMPHONY/Datasets/sample.dat"

to get
"
Reading input file...

ERROR: SYMPHONY can only read GMPL/AMPL files if GLPK is
installed and the USE_GLPMPL compiler define is set.
Exiting.

"

What are the missing steps?
