[Symphony] Symphony error in reading AMPL files

[Arun Yadav]

Hi Ted,
As instructed in the manual I ran the get.glpk script and then configured
and installed Symphony. It still gives me the following error when trying
to read gmpl input file,

==  Welcome to the SYMPHONY MILP Solver

Reading input file...

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


Fatal errors encountered. Exiting with code -120.
See sym_return_values.h for meaning of code.

Regards,
​Arun Yadav​
