Function Documentation

OSG_EXPORT const char* osgGetLibraryName

(

)

The osgGetLibraryName() method returns the library name in human-friendly form.

OSG_EXPORT const char* osgGetSOVersion

(

)

The osgGetSOVersion() method returns the OpenSceneGraph soversion number.

OSG_EXPORT const char* osgGetVersion

(

)

osgGetVersion() returns the library version number. Numbering convention : OpenSceneGraph-1.0 will return 1.0 from osgGetVersion.

This C function can be also used to check for the existence of the OpenSceneGraph library using autoconf and its m4 macro AC_CHECK_LIB.

Here is the code to add to your configure.in:

 #
 # Check for the OpenSceneGraph (OSG) library
 #
 AC_CHECK_LIB(osg, osgGetVersion, ,
    [AC_MSG_ERROR(OpenSceneGraph library not found. See http://www.openscenegraph.org)],)
