Hi,
i tried the cmake file you attached. It is does what it is expected (building
with libc++ and c++11 as language dialect).
But i think i mixed two things in here. First the linking error of OSG itself,
which was not solved by linking against libc++. This was a problem of linking
against OSG after it has been built. This was fixed when linking osg against
libc++ which is now configurable using the flag mentioned by Stefan. So for me
it makes sense to include the changes to osg.
Nevertheless, the issue with linking osgGA serializer plugin and the missing
symbols is still there. I managed to build osg, but i am currently not able to
reproduce this. I noticed that the build works once after cmake-ing osg via
commandline (cmake .. -DCMAKE_PREFIX_PATH=/Users/jklimke/Qt/5.1.0/clang_64
-DCMAKE_BUILD_TYPE=Release). But when trying to build a second time it refuses
to link the osgga serializer. Is there anything special with this library ?
Here's again the error i am getting with a more verbose output. All necessary
libaries should be included in the link
