[Insight-users] Problem building QtImageViewer

[Jarek Sacha]

I have problem compiling QtImageViewer. I am running RedHat 8, gcc 3.2,
qt3.0.5, recent CVS ITK. First Makefile generates warnings:

----------------------------------------
Makefile:300: warning: overriding commands for target `QtSlicerGUI.o'
Makefile:292: warning: ignoring old commands for target `QtSlicerGUI.o'
Makefile:324: warning: overriding commands for target `QtSlicerHelpGUI.o'
Makefile:316: warning: ignoring old commands for target
`QtSlicerHelpGUI.o'
----------------------------------------

Looks that targets `QtSlicerGUI.o' and `QtSlicerHelpGUI.o' are generated
twice, here is a snipped from Makefile:

----------------------------------------
287: #---------------------------------------------------------
288: # Build QtSlicerGUI.o  From
/home/sacha/src/tmp/QtImageViewer/QtSlicerGUI.h
289: #

292:	echo "$(CMAKE_CXX_COMPILER) $(CMAKE_CXX_FLAGS) $(INCLUDE_FLAGS) -c

293:	$(CMAKE_CXX_COMPILER) $(CMAKE_CXX_FLAGS) $(INCLUDE_FLAGS) -c
/home/sacha/src/tmp/QtImageViewer/QtSlicerGUI.h -o QtSlicerGUI.o

295: #---------------------------------------------------------
296: # Build QtSlicerGUI.o  From
/home/sacha/src/tmp/QtImageViewer/QtSlicerGUI.cxx
297: #

299: QtSlicerGUI.o: /home/sacha/src/tmp/QtImageViewer/QtSlicerGUI.cxx
300:	echo "$(CMAKE_CXX_COMPILER) $(CMAKE_CXX_FLAGS) $(INCLUDE_FLAGS) -c

301:	$(CMAKE_CXX_COMPILER) $(CMAKE_CXX_FLAGS) $(INCLUDE_FLAGS) -c
/home/sacha/src/tmp/QtImageViewer/QtSlicerGUI.cxx -o QtSlicerGUI.o
----------------------------------------

Make fails linking QtSlicer:

----------------------------------------

Note that I can compile and run QtITK example application fine.

Help resolving this greatly appreciated.
