[Lemon-user] Using Lemon with CPLEX Concert on Windows with Visual C++ 2008

[Luis de la Torre]

I'm trying to use Lemon and CPLEX Concert in the same code. I'm
running into linker problems. Concert has a number of settings in its
installation instructions, and after adding and removing them one by
one the culprit seems to be setting the runtime library to
multi-threaded (/MT).

Below are the linker errors I'm getting, and the code that gives me
these errors when I try to link. Without the the change of runtime
library to multi-threaded, the code compiles and runs correctly.

Does anyone know what settings I should be using to use CPLEX together
with Lemon?

Thank you,

Luis de la Torre

  graphFile.close();
