Thanks a lot i will do the changes suggested and see if it works
Hello everyone and thank you in advance for your help
I would like to call a external C++ function written in coin linear programming .test1.cpp whose code is
#include<iostream>
#include"include/coin/OsiSolverInterface.hpp"
#include "include/coin/OsiClpSolverInterface.hpp"
#include "CoinUtils/src/CoinPackedMatrix.hpp"
#include "CoinUtils/src/CoinPackedVector.hpp"
int linp(void)
{
int nCons = 7;//Number of constraints
int nVars = 2;//Number of variables
double Obj_Func[2] = {-1,-1/3};//Objective Function
double conMatrix[14]={1,1/4,1,1,1,1/4,1,-1,-1/4,-1,-1,-1,-1,1};//Constraint Matrix
double conUB[7]={1/2,2,1,2,1,-1,2};//Constraint Upper Bound
double conLB[7] = {1/2, -10000000, -10000000, -10000000, -10000000, -10000000, -10000000}; //Constraint Lower Bound
double LB[2]={-1,-0.5};//Variable Lower Bound
double UB[2]={1.5,1.25};//Variable Upper Bound
double options[1] = {3000.0};
OsiSolverInterface* si = new OsiClpSolverInterface();
//Defining the constraint matrix
CoinPackedMatrix *matrix = new CoinPackedMatrix(false , 0 , 0);
matrix->setDimensions(0 , nVars);
for(int i=0 ; i<nCons ; i++)
{
CoinPackedVector row;
for(int j=0 ; j<nVars; j++)
{
row.insert(j, conMatrix[i+j*nCons]);
}
matrix->appendRow(row);
}
//setting options for maximum iterations
si->setIntParam(OsiMaxNumIteration,options[0]);
//Load the problem to OSI
si->loadProblem(*matrix , LB , UB, Obj_Func , conLB , conUB);
//Solve the problem
si->initialSolve();
//Output the solution to Scilab
//get solution for x
const double* xVal = si->getColSolution();
double* xValue = const_cast<double*>(xVal);
for (int i = 0; i<nVars;i++)
{
std::cout <<"var"<<i<<" = "<<xValue[i]<<"\n";
}
//get objective value
double objValue = si->getObjValue();
return 0;
}
it runs fine in gcc
I have converted it into object file test1-utf8.o using gcc in ubuntu 16.04
and i am calling it from the modelica code
model test1
function Ex
output Integer k;
external k=linp()annotation(Include="#include\"test1-utf8.o\"",Library="OsiClp",Library="Clp",Library="ClpSolver",Library="CoinUtils",Library="Osi");
end Ex;
Integer k;
equation
k=Ex();
end test1;
it gives the error
