I understand, but the error is located in a single point, not related to 
anything else, and the hierarchy is fairly complex and not easily cut.

Well, my platform is not OSX but the directive seems fine and it is not 
end user code but was generated by sip.

I don't want the typedefs to be global, that is not the point.

Given the class:

template <DataType>
class QCPAbstractPlottable1D :
   public QCPAbstractPlottable, public QCPPlottableInterface1D /Abstract/
{
%TypeHeaderCode
#include <QCustomPlot/src/qcp.h>
typedef QCPAbstractPlottable1D<QCPGraphData>
   QCPAbstractPlottable1D_QCPGraphData;
typedef QCPAbstractPlottable1D<QCPBarsData>
   QCPAbstractPlottable1D_QCPBarsData;
%End
...
};


The generated code is:

#include <QCustomPlot/src/qcp.h>
typedef QCPAbstractPlottable1D_QCPBarsData<QCPGraphData>
   QCPAbstractPlottable1D_QCPBarsData_QCPGraphData;
typedef QCPAbstractPlottable1D_QCPBarsData<QCPBarsData>
   QCPAbstractPlottable1D_QCPBarsData_QCPBarsData;

Note that the typedefs have been somewhat elaborated, not just copied 
verbatim and somehow got screwed.
Maybe this is intentional and for sure I am by no means a SIP expert but 
at least it looks weird.
If it is intentional please excuse me for the unneeded noise.
