Hi,
This is driving me mad. I didn't have this problem when I built 64bit cocoa,
but I had to backstep to carbon due to some issues with wxWindow 2.9.1 cocoa
64bit compatibility issues at the moment.6
I get the following unresolved OpenThreads link error with GCC 4.2/Xcode 3.2,
running OSX 10.6.5.
<snip>

The Xcode 3.2 compile command, which is rather thick since it includes static
*.a for wxWindows/carbon 32bit, looks like this:

And the link command, also rather thick-- however note the framework reference
to OpenThreads (-framework OpenThreads) looks like this:

I build osg (and tested the various built apps to make sure they work) with the
32bit carbon; both release and debug. The 32bit carbon release
OpenThreads.framework directory looks like this:
<snip>
teddymac:Current tmorris$ ls
Headers OpenThreads Resources
teddymac:Current tmorris$ ls -l
total 144
drwxr-xr-x 14 tmorris staff 476 Jan 6 22:23 Headers
-rwxr-xr-x 1 tmorris staff 69944 Jan 6 22:23 OpenThreads
drwxr-xr-x 3 tmorris staff 102 Jan 6 22:23 Resources
<snip>
Anyone have any insights or advise? Again the osg example apps, etc. work fine.
So, my guess is that I'm missing something obvious. Staring at this too long, I
think. ;-y
Thank you!
Cheers,
Ted
