Question

我的班级有地图作为会员。问题是这个映射的值是boost :: shared_ptr。当我尝试将一些ement插入map时，发生了一些不友好的编译错误。这是我的源代码的一部分：标题：

class Chi2Analyzer: public BaseAlgorithm{

typedef boost::unordered_map<std::string, boost::shared_ptr<TH1D> > HistogramsMap; /* ... */
private:

HistogramsMap h_map;

的.cpp：

Chi2Analyzer::Chi2Analyzer()
{
    // initialization of the map
    /////////////////////////////////////////////////////////////////
    // chi2
    std::string histogramName="chi2PerDof";
    boost::shared_ptr<TH1D> histogram;
    histogram.reset(new TH1D(histogramName.c_str(),histogramName.c_str(), 100,0,1.6e6) );
    h_map[histogramName]=histogram;

和g ++输出：

                 from src/../Include/NTupleHandler.h:11,

我该怎么做才能解决这个错误。最诚挚的问候
