Question

我对glpk很陌生。我有以下型号

  #include <iostream>
  #include <csignal>
  #include <unistd.h>
  using namespace std;

  class Crap {
    public:
    Crap() {};
    ~Crap() {printf("destructor called\n");} 
  };

  Crap* p;
  static volatile sig_atomic_t got_signal = 0;

  void signalHandler( int signum ) {
     // AVOID REENTRANCY !!!!
     got_signal = 1;
  }

  int main () {
     signal(SIGINT, signalHandler);  

     // ON HEAP
     p = new Crap;


     while(1) {
        cout << "PLEASE GIVE ME A SIGINT SIGNAL" << endl;
        if(got_signal == 1){
            delete p; // DELETE OBJECT ON HEAP AND CALL DESTRUCTOR 
            exit(0);
        }
        sleep(1);
     }

     return 0;
  }

我收到以下错误：

set MES;
set MAYORISTA;

data;
set MES := 1 2 3 4 5 6 7 8 9 10 11 12;

end;

我不知道这是怎么回事。我不确定这是语法错误还是从参数定义派生而来的错误。错误出在股票变量上，除此之外我真的不知道该如何定义它们。我迷路了，在这里我将不胜感激

无法在glpk模型中找出表达式中的语法错误
