CCfits库演示代码无法正常工作

我是C ++的新手。最后,我正在尝试从python中翻译一些代码,以便对某些超新星模拟进行分析。但是,为了做到这一点,我必须能够将.fits文件作为数组导入到我的C ++代码中。我下载了cfitsio和ccfits库,它们似乎安装正确,因为包含#include <CCfits>的简单代码和带有print语句的int main编译并运行。但是,从NASA(http://heasarc.gsfc.nasa.gov/fitsio/CCfits/html/readimage.html)获取名称更改为.fits文件的演示代码我希望打开(在我的主目录中)以使用这些库导入.fits文件无法编译。我正在使用的精确代码(Sobelattempt.cc)是:

#include <CCfits>
#include <iostream>
#include <cmath>
#include <memory>
using namespace CCfits;
int readimage()
{
     std::auto_ptr<FITS> pInfile(new FITS("Supernova45F.fits",Read,true));

     PHDU& image=pInfile->pHDU(); 

     std::valarray<unsigned long>  contents;

     // read all user-specifed, coordinate, and checksum keys in the image
     image.readAllKeys();

     image.read(contents);

     // this doesn't print the data, just header info.
     std::cout << image << std::endl;

     long ax1(image.axis(0));
     long ax2(image.axis(1));

     for (long j = 0; j < ax2; j+=10)
     {
             std::ostream_iterator<short> c(std::cout,"\t");
             std::copy(&contents[j*ax1],&contents[(j+1)*ax1-1],c);
             std::cout << '\n';       
     }

     std::cout << std::endl;
      return 0;   
}

int main(){
return 0;
}

我正在使用命令进行编译:

g++ Sobelattempt.cc -o Sobel -I/home/Sam/CCfits -I/home/Sam/cfitsio

我得到了错误:

链接到CCfits库的两个链接器选项是-lCCfits -lcfitsio。另外,-L ...标志 如果LD_LIBRARY_PATH没有覆盖具有这两个库的目录,则可能需要。
