Hi,
We are using OSG for a cross-platform application that runs on Windows, Linux
and Mac OS X (10.10 and 10.11).
The application uses OSG 3.4 and Qt 4.8 and we had to apply some patches to get
this setup working. We maintain a public Git clone, based on the GitHub mirror
of OpenSceneGraph.
I don't have enough posts on this forum to include a link to the repo. I can
share it by private messages or some other way, if anybody is interested.
We are using this Git clone internally and we haven't had the time to clean it
up and submit these changes back upstream (we're not even sure all the changes
we've made are general enough to be integrated upstream).
Here is a patch that could help with the compilation:
diff --git a/CMakeLists.txt b/CMakeLists.txt
index ce2815b..3e496c1 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

Additionally, here are the CMake configuration flags we are using to compile
OSG:
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DOPENGL_PROFILE="GLCORE" \
-DCMAKE_EXE_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_MODULE_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_SHARED_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_OSX_ARCHITECTURES="x86_64" \
-DOSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX="imageio" \
-DOSG_WINDOWING_SYSTEM="Cocoa" \
-DDESIRED_QT_VERSION=4 \
-DQT_QMAKE_EXECUTABLE=/usr/bin/qmake \
-DDYNAMIC_OPENSCENEGRAPH=OFF \
-DDYNAMIC_OPENTHREADS=OFF
I hope this helps!
Best regards,
Radu
