Hi, I think I know what the problem is. I'm getting the same unresolved symbols building on MacOS 10.4 and OSG 2.6.1 using cmake. Your link line has
/usr/lib/libm.dylib rather than your SDK version of the library. I don't know much about these things myself as I've only been using a Mac for about 1 day now but this blog entry details the issue http://www.red-sweater.com/blog/246/missing-link As far as cmake goes, and I've only been looking at _that_ for about 2 days, it seems the problem is in the top-level CMakeLists.txt file where it has the line FIND_LIBRARY(MATH_LIBRARY m) wrapped in an IF(UNIX) clause. I think this particular line should also be wrappend in an IF(NOT APPLE) clause. Doing this fixes up the link lines for me and the problem goes away. As I say I'm certainly no Mac expert so maybe this isn't quite right. I'm certainly not confident enough to post it to osg-submissions :) I haven't looked at the Xcode project at all but I imagine something similar must be going on there?
