computeBound function return type error

[spaghetti-]

Hello, I'm with osg 3.4 and I'm getting this error on compilation

In file included from /opt/uwsim/src/uwsim_osgocean/src/osgOcean/MipmapGeometryVBO.cpp:18:
/opt/uwsim/src/uwsim_osgocean/include/osgOcean/MipmapGeometryVBO:147:26: error: virtual function 'computeBound' has a different return type ('osg::BoundingBox' (aka 'BoundingBoxImpl<osg::Vec3f>')) than
      the function it overrides (which has return type 'BoundingSphere' (aka 'BoundingSphereImpl<osg::Vec3f>'))
        osg::BoundingBox computeBound( void ) const;
        ~~~~~~~~~~~~~~~~ ^
/usr/local/include/osg/Drawable:160:32: note: overridden virtual function is here
        virtual BoundingSphere computeBound() const;
                ~~~~~~~~~~~~~~ ^

It seems that the API has changed: xarray/osgRecipes#13

I'll submit a PR if I manage to get around this issue. I'm on the indigo-devel branch.

Hello, I have the same problem as you. Can you tell me how to solve it? I don't know where to use OSG_ VERSION_ Greeter macro, thank you

Hello, did any of you find a solution to this?
My code compiled, when I tried to return a BoundingBox from within the function body, but in the head wrote osg::BoundingSphere as return type.
Yet this made me run into the next error:

/usr/bin/ld: CMakeFiles/MyProject.dir/main.cpp.o: undefined reference to symbol 'glFrontFace'
/usr/bin/ld: /lib/x86_64-linux-gnu/libGL.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/MyProject.dir/build.make:108: MyProject] Error 1
make[1]: *** [CMakeFiles/Makefile2:95: CMakeFiles/MyProject.dir/all] Error 2
make: *** [Makefile:103: all] Error 2

Anybody know a solution to this?
