C命令行参数Eclipse CDT？

我使用这个代码 http://sicktoolbox.sourceforge.net/>的示例程序 http://sourceforge.net/projects/sicktoolbox/files/.它基本上是距离扫描仪驱动程序.我试图运行的程序是在sicktoolbox-1.0.1 / c / examples / lms / lms_plot_values中,以防你想看到我在说的代码.

无论如何,lms_plot_values项目文件夹包含gnuplot_i.cc,gnuplot_i.hpp,main.cc,Makefile,Makefile.am,Makefile.in.所以我把前三个文件放在我的Eclipse Indigo CDT中,编译(没有编译器错误,所有在Eclipse中已经正确连接的所有库都添加了),但是这个示例程序是用来写入命令行参数的.这是代码获得的一切.

/* Implementation dependencies */
#include <stdlib.h>
#include <string>
#include <vector>
#include <signal.h>
#include <iostream>
#include <sicklms-1.0/SickLMS.hh>
#include "gnuplot_i.hpp"

using namespace std;
using namespace SickToolbox;

bool running = true;
void sigintHandler(int signal);

int main(int argc,char * argv[]) {

  string device_str; // Device path of the Sick LMS 2xx
  SickLMS::sick_lms_baud_t desired_baud = SickLMS::SICK_BAUD_38400;

  /* Check for a device path.  If it's not present,print a usage statement. */
  if ((argc != 2 && argc != 3) || (argc == 2 && strcasecmp(argv[1],"--help") == 0)) {
    cout << "Usage: lms_plot_values PATH [BAUD RATE]" << endl
     << "Ex: lms_plot_values /dev/ttyUSB0 9600" << endl;
    return -1;
  }

正如它所说,它会抛出一个错误,并杀死程序,说要我从命令行输入“lms_plot_values / dev / ttyUSB0 9600”来运行程序,但我不能这样做,我想要在日食中做一切,所以我不想这样做.我试过添加：

argv[1] = "/dev/ttyUSB0";
argv[2] = "9600";

但是,由于argc检查,这不行.你知道是否传入“lms_plot_values / dev / ttyUSB0 9600”,为什么会期待或从哪里获取argc值？或者我怎么能认为这些参数是通过的？我不太熟悉C如此工作,我只使用Java.

感谢任何帮助
