My usage of CPLEX is somewhat advanced -- I have to use some sort of repeated branch and cut with cut callbacks to solve large difficult integer programs. Efficiency is critical and in our experience CPLEX performs quite adequately in its correctness.

I will try the various ideas suggested and see ...

Thanks for the explanation.

In my application, I have to use another library only by static linking since the providers of that library (CPLEX) do not provide shared linking for linux. I went ahead trying to include polymake and was able to compile and link/build successfully. However, linking now ...

Hello,

This is more a C++ linking/compiling question rather than a polymake question.

This line from polymake's documentation seems to suggest that a "unix emulation" is needed on Windows https://polymake.org/doku.php/install/install:

polymake is not supported on any native Windows platform. You ...

Hello,

In PORTA, I process the test.poi file with content reproduced below (the online message system does not allow me to attach a .poi file):

DIM = 6
CONV_SECTION
0 1 1 0 0 1
1 0 0 1 1 0
0 0 1 1 0 1
1 0 0 1 1 0
0 1 1 0 0 1

In general: no. Rational is an exact type, double is not. If a conversion makes sense or not will depend on what you want to compute.
Usually, you just want to stick with Rational. polymake supports arithmetic, linear algebra etc. Why do you want to convert at all?


I have other functions in my ...

Thanks gawrilow and joswig. I have been able to make progress based on your comments. My code currently is:

#include <polymake/Main.h>
#include <polymake/Matrix.h>
#include <polymake/SparseMatrix.h>
#include <polymake/Rational.h>
using namespace polymake;
int main(int argc, const char* argv ...

Hello,

I have the following code in C++:

#include <polymake/Main.h>
#include <polymake/Matrix.h>
#include <polymake/SparseMatrix.h>
#include <polymake/Rational.h>
using namespace polymake;
int main(int argc, const char* argv[]) {
try {
const int dim = 4;
Main pm;
pm.set_application("polytope ...

Sure, I would be happy to help via some tests if needed. I have access to a WSL and a pure ubuntu machine. I will pm my email detail.

On a WSL machine, with no previous polymake installation, building from source gave rise to the following: the /usr/lib/polymake folder does not have perlx or config ...

Indeed building from source code did the trick. The symlink was not created by default. I had to do the following manually:

:/usr/lib/polymake$ sudo ln -s ../../share/polymake/ shared

The c++ code compiled and ran fine. I obtained the following output:

polymake: used package cdd
cddlib ...

Creation of the symlink eliminated that error. Now, there is a new error on that very line:

Can't locate Polymake/Main.pm in @INC (you may need to install the Polymake::Main module) (@INC contains: /usr/share/perllib /usr/lib/polymake/perlx/5.30.0/x86_64-linux-gnu-thread-multi /usr/lib/polymake ...
