nanogui: Thread: [Solved] Multiple definition error when building Nano-X with VNC server

Found my problem,

 From drivers/Object.rules

ifeq ($(HAVE_VNCSERVER_SUPPORT), Y)
MW_CORE_OBJS += $(MW_SUBDRIVER_OBJS)
MW_CORE_OBJS += $(MW_DIR_OBJ)/drivers/vncserver.o
endif

This includes the subdriver objects a second time. Removing
the line fixed the problem.
