Help adding LPSOLVE on Debian x64
Богданов Александр Павлович
Hello!
My name is Aleksandr, I am an analyst at NefteTransService
We have purchased a single-user license for AMPL and working on building and testing models.
However we have some issues with connecting LPSOLVE for AMPL.
We are using Debian x64, but I was not able to find lpsolve only for 32bit architecture.
Maybe you can help me find appropriate LPSOLVE? Or instruct me how to build it? Or recommend any other option?
PS: Currently we are using CBC solver, in future we might switch to CPLEX or Gurobi.
С уважением,

If you need to build 64-bit lp_solve binaries, see the "Using lpsolve from AMPL section" of the lp_solve Reference Guide -- particularly the instructions headed "Compile the AMPL driver" that appear at the end of the section. NOTE: The link for the AMPL-solver library is wrong; instead, use https://ampl.com/netlib/ampl/solvers.
On Hans Mittelmann's MIPLIB2017 Benchmark Instances page, there a comparison of the timings for several mixed-integer programming solvers, including CBC, lp_solve, and Gurobi.

If you are able to install 32-bit libraries for Debian, then you should be able to run the 32-bit version of lp_solve. The only advantage of a 64-bit version would be the ability to use more than 4GB of memory, but lp_solve is mostly useful for small-to-medium problems that use much less memory that that.
