Question

I’m attempting to get the following code from nmdepend to compile

const std::string Bfd::packageName(const fs::path& path, int packageLevel)
{
  fs::path::iterator p = path.end();
  --p;

  for(int i = 0; i < packageLevel; ++i)
      --p;

  return *p;
}

However it is generating the following compiler error

/Users/nick/Software/nmdepend/src/Bfd.cpp: In static member function ‘static const std::string Bfd::packageName(const boost::filesystem3::path&, int)’:
/Users/nick/Software/nmdepend/src/Bfd.cpp:27: error: conversion from ‘const boost::filesystem3::path’ to non-scalar type ‘const std::string’ requested

How should this code be modified so that a string is returned yet the manipulation that is being attempted by using an iterator is maintained?

Answer 1

path is not implicitly convertible to string. This should work though:

return p->string();
