Hello,
On one of my machines I just switched over to Snow Leopard, so I did a fresh
CVS grab of ParaView. I have Qt 4.5.3 built from source for Cocoa (x86 and
x86_64 architectures), and I have been trying to build ParaView (i386;x86_64),
but keep getting a linking error on the pqWidgets library:
[ 90%] Built target QtTesting
Linking CXX shared library ../../bin/libpqWidgets.dylib
Undefined symbols:
"_objc_msgSend", referenced from:
pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
Undefined symbols:

pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
pqProgressBarHelper::setProgress(int) in pqProgressBarHelper.mm.o
ld: symbol(s) not found
I found I can get past this if I add a "-framework Cocoa" to the linker line
manually, so I think in ParaView3/Qt/Widgets/CMakeLists.txt maybe there should
be another check added, something like (line 198):
if(VTK_USE_COCOA)
TARGET_LINK_LIBRARIES(pqWidgets "-framework Cocoa")
endif(VTK_USE_COCOA)
The progress bar doesn't really work and I'm running into the "grayed out
filters" that some others have mentioned (filters show up right after launching
PV, I can generate or load a "source", and I can apply one filter, but then
they disappear after that and won't come back), but at least PV compiled... :)
Not sure if it's relevant, but in case it's helpful: On another machine with a
very similar setup (Snow Leopard and x86,x86_64 Cocoa Qt 4.5.2 from source),
but just CVS "update" and rebuild on an old checkout rather than a fresh one, I
noticed that the pqWidgets_LIB_DEPENDS (and a bunch of other things) include
;general;-framework Carbon;general;-framework AppKit;general;-framework
ApplicationServices; The progress bar doesn't work on that version, either,
but I don't get the "grayed out" filters problem.
Thanks,
-Eric
