Fedora installation issues

[anthonysirico]

I am using Fedora 41 so I downloaded Or-Tools for Fedora 39 cpp. I ran the make test and everything passed. Now i am trying to run one of the examples:

#include <iostream>
#include <memory>

#include "ortools/linear_solver/linear_solver.h"
// [END import]

namespace operations_research {
void LinearProgrammingExample() {
  // [START solver]
  std::unique_ptr<MPSolver> solver(MPSolver::CreateSolver("SCIP"));
  if (!solver) {
    LOG(WARNING) << "SCIP solver unavailable.";
    return;
  }
  // [END solver]

  // [START variables]
  const double infinity = solver->infinity();
  // x and y are non-negative variables.
  MPVariable* const x = solver->MakeNumVar(0.0, infinity, "x");
  MPVariable* const y = solver->MakeNumVar(0.0, infinity, "y");
  LOG(INFO) << "Number of variables = " << solver->NumVariables();
  // [END variables]

  // [START constraints]
  // x + 2*y <= 14.
  MPConstraint* const c0 = solver->MakeRowConstraint(-infinity, 14.0);
  c0->SetCoefficient(x, 1);
  c0->SetCoefficient(y, 2);

  // 3*x - y >= 0.
  MPConstraint* const c1 = solver->MakeRowConstraint(0.0, infinity);
  c1->SetCoefficient(x, 3);
  c1->SetCoefficient(y, -1);

  // x - y <= 2.
  MPConstraint* const c2 = solver->MakeRowConstraint(-infinity, 2.0);
  c2->SetCoefficient(x, 1);
  c2->SetCoefficient(y, -1);
  LOG(INFO) << "Number of constraints = " << solver->NumConstraints();
  // [END constraints]

  // [START objective]
  // Objective function: 3x + 4y.
  MPObjective* const objective = solver->MutableObjective();
  objective->SetCoefficient(x, 3);
  objective->SetCoefficient(y, 4);
  objective->SetMaximization();
  // [END objective]

  // [START solve]
  const MPSolver::ResultStatus result_status = solver->Solve();
  // Check that the problem has an optimal solution.
  if (result_status != MPSolver::OPTIMAL) {
    LOG(FATAL) << "The problem does not have an optimal solution!";
  }
  // [END solve]

  // [START print_solution]
  LOG(INFO) << "Solution:";
  LOG(INFO) << "Optimal objective value = " << objective->Value();
  LOG(INFO) << x->name() << " = " << x->solution_value();
  LOG(INFO) << y->name() << " = " << y->solution_value();
  // [END print_solution]
}
}  // namespace operations_research

int main(int argc, char** argv) {
  operations_research::LinearProgrammingExample();
  return EXIT_SUCCESS;
}

and i am receiving

/usr/bin/ld: cannot find -lortools: No such file or directory
collect2: error: ld returned 1 exit status

Note that i am new to c++ so let me know if there is a basic error in my code.

Also, my ~/.bashrc file reads:

export LD_LIBRARY_PATH="/home/anthonysirico/CLionProjects/FlightScheduler/scheduler/cpp/or-tools_x86_64_Fedora-39_cpp_v9.11.4210/lib:$LD_LIBRARY_PATH"
export CPLUS_INCLUDE="/home/anthonysirico/CLionProjects/FlightScheduler/scheduler/cpp/or-tools_x86_64_Fedora-39_cpp_v9.11.4210/include:$CPLUS_INCLUDE_PATH"
export PATH="/home/anthonysirico/CLionProjects/FlightScheduler/scheduler/cpp/or-tools_x86_64_Fedora-39_cpp_v9.11.4210/bin:$PATH"

First it is a link time error so your "source code" compile BUT compiler didn't manage to link the executable with the needed library.

May we know the command line(s) you used to compile/build/run your program ?
note: also if you have a trace of your cli with the last commands...
