linking Error for hidden symbols in static library (how to resolve this hidden symbol error while linking)

[TechEnthusiast]

When I build static libraries of libQtGui and libQtCore CXXFLAGS -fvisibility=hidden is used for compiling each file of QtCore and QtGui. When I link this library in my final executable , then I get following

hidden symbol `_ZNK7QLayout11minimumSizeEv' is referenced by DSO linking ld: final link failed: Bad value

What is correct solution to remove the linking error hidden symbol `_ZNK7QLayout11minimumSizeEv' is referenced by DSO is referenced by DSO

Also I have a query I make shared library with the same code base of QtCore and QtGui and also CXXFLAGS -fvisibility=hidden and when I link the shared libraries libQtCore.so and libQtGui.so in my final executable then it works fine and I do not get any linker error
