[osg-users] [build] Can't execute Qt example in IOS environment

[Christophe Lhe]

Hi,

My platform is Emac 10.9 with IOS sdk 8.2.

I succedeed in compiling OSG 3.4 for IOS.

I inserted the viewerQT example in QT creator, and added osgplugin.h found in osgviewerIphone example (needed for static lib).

But I have following error when I launch the viewerQT with the data file robot.osg :


Code:
Warning: detected OpenGL error 'invalid enumerant' at Before Renderer::compile

Any help would be appreciated to have OSG working with QT on IOS...



Here is the cmake configuration : 
        -DOSG_BUILD_PLATFORM_IPHONE:BOOL=ON 
        -DDYNAMIC_OPENSCENEGRAPH:BOOL=OFF 
        -DDYNAMIC_OPENTHREADS:BOOL=OFF 
        -DIPHONE_SDKVER:STRING=8.2 
        -DBUILD_OSG_APPLICATIONS:BOOL=OFF 
        -DBUILD_OSG_EXAMPLES:BOOL=OFF 
        -DOPENGL_PROFILE:STRING=GLES2 
        -DOSG_USE_QT:BOOL=ON 
        -DQt5Core_DIR:STRING=/Users/qt/Qt5.5.1/5.5/ios/lib/cmake/Qt5Core 
        -DQt5Gui_DIR:STRING=/Users/qt/Qt5.5.1/5.5/ios/lib/cmake/Qt5Gui \
        -DQt5OpenGL_DIR:STRING=/Users/qt/Qt5.5.1/5.5/ios/lib/cmake/Qt5OpenGL \
        -DQt5WebKitWidgets_DIR:STRING=/Users/qt/Qt5.5.1/5.5/ios/lib/cmake/Qt5WebKitWidgets \
        -DQt5Widgets_DIR:STRING=/Users/qt/Qt5.5.1/5.5/ios/lib/cmake/Qt5Widgets

And I added following lines in CMakeLists.txt :
        set (CMAKE_FIND_ROOT_PATH ${IPHONE_DEVROOT} ${IPHONE_SDKROOT} ${CMAKE_PREFIX_PATH} CACHE string  "iOS find search path root")
        set (CMAKE_FIND_FRAMEWORK FIRST)
        set (CMAKE_SYSTEM_FRAMEWORK_PATH
              ${IPHONE_SDKROOT}/System/Library/Frameworks
              ${IPHONE_SDKROOT}/System/Library/PrivateFrameworks
              ${IPHONE_SDKROOT}/Developer/Library/Frameworks
        )
        set (CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
        set (CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
        set (CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
... 


Thank you!

Cheers,
