[osg-users] [build] Xocde 7.1 with osgDB compiler error

[Radu Popescu]

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

+    ENDIF()
 
     SET(OSG_OSX_SDK_NAME "macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")



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
