[Help-glpk] GLPK Maximum row limit error

[Vignesh Sridharan]

Hello,

I am using GLPK to create an LP file which I will later optimize using CPLEX. 

But while I am creating the LP file, the following error occurs.

#####

glp_add_rows: nrs = 186919944; too many rows

error detected in file ..\src\glpapi01.c  at  line  251

#####

I checked the resepectiv .C file and found that GLPK has a row limit of 100000000. Can this limit be changed ? 

Could you help me with a way around this issue ?

For the back ground. This model is a energy systems model on the likes of MARKAL in open source. This problem occurs when I am trying to model the whole of Africa's energy system (more than 10 countries at a time). My GNU Mathprog code is 470 line long and my data file is 1000000 lines long.

thanks
