C++ enum is not a member of

I am trying to access a enum that is defined in a class of a library (ogdf) I use.

See line 65 here for the definition of the enum in the library.

If I try to access it like that (which I would think is the correct way):

ogdf::StressMinimization::TERMINATION_CRITERION::POSITION_DIFFERENCE

I get the following error:

error: ‘ogdf::StressMinimization::TERMINATION_CRITERION’ has not been declared

If I try to do it like that:

ogdf::StressMinimization::POSITION_DIFFERENCE

I get this error:

error: ‘POSITION_DIFFERENCE’ is not a member of ‘ogdf::StressMinimization’

Of course I'm including the header in my .cpp file via:

#include <ogdf/energybased/StressMinimization.h>

As this is part of the ogdf library, there are no problems with circular includes, which seems to be most frequent problem that causes that.

I can't see why this is happening, any help is greatly appreciated! If you need any further details, please let me know, I'll update the question.

Assuming that you're on the latest, it may be that the name of the enum changed and that documentation is old; looks like that documentation is from 2015, latest snapshots are (currently) from February 2017. From https://github.com/ogdf/ogdf/blob/master/include/ogdf/energybased/StressMinimization.h, the enum looks like this now:

enum class TerminationCriterion {
    None, PositionDifference, Stress
};

So, try replacing TERMINATION_CRITERION with TerminationCriterion and/or POSITION_DIFFERENCE with PositionDifference and see if that works.
