OMNeT compilation problem

[Ivo Calado]

Hi fellows, i'm dealing with a strange problem to build omnet with osg support enabled. Whenever I try to build the compilation stops with following error message:

Creating executable: out/gcc-release//osg-earth
out/gcc-release//OsgEarthScene.o: In function `OsgEarthScene::initialize()':
OsgEarthScene.cc:(.text+0x4f3): undefined reference to `omnetpp::cOsgCanvas::setEarthViewpoint(osgEarth::Viewpoint const&)'
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:118: out/gcc-release//osg-earth] Error 1
make[2]: Leaving directory '/home/ivocalado/opt/omnetpp-5.0/samples/osg-earth'
make[1]: *** [Makefile:117: osg-earth] Error 2
make[1]: Leaving directory '/home/ivocalado/opt/omnetpp-5.0'
make: *** [Makefile:23: allmodes] Error 2

However, during the configure step the support to openscenegraph and osgwarth was conrrectly detected as shown in the generated config.log presented below.

confi.log
configure:5110: checking for OpenSceneGraph with CFLAGS=" -O2 -DNDEBUG=1 -fPIC  -fno-stack-protector " LIBS="-losg -losgGA -losgViewer -losgQt -lOpenThreads"

configure:5167: $? = 0
configure:5168: result: yes

Any tip about how to fix it?

Hi!

Just a quick guess: Have you tried building OMNeT++ in the same directory before, without OSG support enabled/detected? If yes, maybe doing a clean build by running a make cleanall before configuring will help.
If not, make sure all the packages required for OSG and osgEarth support are correctly installed, and are the right versions.
Check with point section 5.3.1. of the Installation Manual for details on this.
Well, let me quote that section to make it easier for you:

"To use Qtenv with 3D visualization support, install the development packages for Qt4,

OpenSceneGraph (3.2) and the osgEarth (2.5 or later) packages:

$ sudo apt-get install qt4-qmake libqt4-dev libqt4-opengl-dev \

 openscenegraph libopenscenegraph-dev openscenegraph-plugin-osgearth \

 osgearth osgearth-data libosgearth-dev"

Hi Attila,

    it worked! I ran make cleanall
