[Insight-users] Build error with SNAP in InsightApplications-2.8.1

[Luis Ibanez]

Hi Martin,


Please try the following:


     Change the declaration of TessCallback in
     line 25 of the file PolygonScanConvert.cxx
     to be:

            typedef GLvoid (*TessCallback)();

     instead of the current:

            typedef void (*TessCallback)();



Please let us know if that works,


    Thanks


       Luis
