Hi,
>From a previous post regarding unresolved externals, I decided to mimic as
>close as possible how one of the examples were built from the
>openscenegraph.xcode project. In this case, I tried two methods.
First, I built the Xcode project from scratch, including the various
frameworks, and macro defs, etc. In the second, instead of the osglogo app, I
started with the osg template. I made sure that the frameworks were referenced
to the OpenSceneGraph 2.8.3 carbon 32 bit release frameworks.
In Either cases, everything compiles correctly but I still get this error:
<snip>
Undefined symbols:
"OpenThreads::Atomic::operator--()", referenced from:
osg::Referenced::unref() constin main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
<snip>
The generated link line, building for 32bit i386, for the 2nd template test
contains the OpenThreads framework (and it is in the same dir as the other osg
Frameworks), as shown below:
Ld
build/Development/osgapp_template_test.app/Contents/MacOS/osgapp_template_test
normal i386
cd /Users/tmorris/osgapp_template_test
/Developer/usr/bin/g++-4.2 -arch i386
-L/Users/tmorris/osgapp_template_test/build/Development

/Users/tmorris/osgapp_template_test/build/Development/osgapp_template_test.app/Contents/MacOS/osgapp_template_test
<snip>
The osglogo.cpp code produces the same result, and therefore I don't repeat it.
I know the frameworks and plugins built correctly because all the example and
executable apps compiled and bundled successfully. Has anyone come across a
similar problem like this? I've stared and plated with various linker and
compile flags and I'm stumped.
Thank you!
Cheers,
Ted
