Recursively scanning the directory for the files

Question

I am trying to iterate over the directory and print the name of all the files starting from the root.

Here's the short snippet I have written using Boost::Filesystem (1.52.0) in my program.

void testApp::getNames(const string& dirPath, string& fileExtension)
{
    namespace fs = boost::filesystem;
    namespace sys = boost::system;
    fs::path filePath(dirPath);
    for(fs::recursive_directory_iterator dir(filePath), dir_end; dir!=dir_end ;++dir)
    {
        cout<<*dir;
    }
}

On trying the compile this, strangely I am getting build errors which points path.hpp file on the following snippet:

    static const codecvt_type& codecvt()
    {
      return *wchar_t_codecvt_facet();
    }

The error that I get is undefined reference to boost::filesystem3::path::wchar_t_codecvt_facet()'|

I am on Ubuntu 12.10 using Codeblocks IDE for my project.

Answer 1

That is a linker error. You need to link with the Boost filesystem library.

In the IDE, there should be a setting for adding libraries somewhere in the project settings. (I don't know exactly where, since I've never used Codeblocks.)
