Function Documentation

const char* osgEarthGetLibraryName

(

)

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

Definition at line 61 of file Version.cpp.

{
    return "osgEarth Library";
}

Here is the caller graph for this function:

const char* osgEarthGetSOVersion

(

)

The osgGetSOVersion() method returns the OSGEARTH shared object version number.

Definition at line 48 of file Version.cpp.

{
    static char osgearth_soversion[32];
    static int osgearth_soversion_init = 1;
    if (osgearth_soversion_init)
    {
        sprintf(osgearth_soversion,"%d",OSGEARTH_SOVERSION);
        osgearth_soversion_init = 0;
    }
    
    return osgearth_soversion;
}

Here is the caller graph for this function:

const char* osgEarthGetVersion

(

)

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

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

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

 #
 # Check for the OSGEARTH (OSG) library
 #
 AC_CHECK_LIB(osg, osgEarthGetVersion, ,
    [AC_MSG_ERROR(OSGEARTH library not found. See http://www.osgearth.org)],)

    static int osgearth_version_init = 1;

    {

        {
            sprintf(osgearth_version,"%d.%d.%d",OSGEARTH_MAJOR_VERSION,OSGEARTH_MINOR_VERSION,OSGEARTH_PATCH_VERSION);

        }
