Comment 2 for bug 1735804

I am compiling trunk-2018.02b and getting the same error as James. I can compile by uncommenting the line

virtual void updateGL(void)

in trunk-2018.02b/gui/qt5/GLViewer.hpp but yade does not start and produces the following error as Janek explained.
--------------------------------
Welcome to Yade 2018.02b
Traceback (most recent call last):

ImportError: /home/subbiah/myyade/install/lib64/yade-2018.02b/py/yade/qt/_GLViewer.so: undefined symbol: _ZN8GLViewer8updateGLEv
--------------------------------

Has there been any update on this issue.
