Exporting a typedef'd symbol

[John E]

A 3rd-party DLL I'm compiling contains the following class (in abbreviated form):-

class __declspec(dllexport) ChordProvider
{
  public:
    ChordProvider () {}  // <--- This gets exported okay

    typedef std::map<std::string,Intervals> ChordNameToIntervals;
    static ChordNameToIntervals tet12_chords; // <--- tet12_chords doesn't get exported
};

The typedef'd symbol doesn't get exported for some reason. Is that fixable?

[Edit...] I tried a few searches via Google / StackOverflow etc and the consensus seems to be that typedefs are compile time objects which should be accessible from outside the DLL without needing to get exported - but I must admit, that's not what I'm seeing here

[Update...] Adding this line to the corresponding cpp file fixed the problem

__declspec(dllexport)  ChordProvider::ChordNameToIntervals ChordProvider::tet12_chords;
