Obviously, this kind of issue happens when the constructor of LAYER_BOX_SELECTOR is not found.
It is in class_layer_box_selector.cpp, compiled in libcommon.a
But it is used also by Gerbview. Is Gerbview compile OK ?

Sometimes this kind of issue happens when object files are not correctly updated,
for instance after modifying compil options or some update in the devel tools.

Usually in this case, a full rebuild of KiCad fixes this issue.
