thanks Bruno

Finally with the debug option and gdb I got the answer about the segmentation fault:
gdb

Welcome to Yade 2017-09-11.git-949a2d9 
.....
Program received signal SIGSEGV, Segmentation fault.
0x00007fffe4dd294c in ?? () from /usr/lib64/libQtGui.so.4

I have compiled yade with the QT5=ON option BUT the program is still looking at the /usr/lib64/libQtGui.so.4 which is linked to the QT4 version!
I think that is a problem inside the cmake script ?

indeed the /usr/lib64/libQt5Gui.so.5 and the /usr/lib64/libQt5Gui.so.4
are both present in the computer.

So I moved down to QT4 and the yade program is running well!
