I am using Mac's framework named "System/Library/Frameworks/DiscRecording.framework" in my qt App. For this I added 2 lines in .pro file.

QMAKE_LFLAGS += -L/System/Library/Frameworks/DiscRecording
LIBS += -framework DiscRecording

In one of my header file I included this framework e.g
#include "DiscRecording/DiscRecording.h" // Including master header file for the framework

but when I try to create object of one of the class on that framework "e.g DRDevice obj", I am getting this error:
"error: 'DRDevice' does not name a type"

How to remove this error
