Error when making trajopt, fatal error: osg/CameraNode: No such file or directory compilation terminated.

[mchuruvija]

I'm following the instalation instructions on http://rll.berkeley.edu/trajopt/doc/sphinx_build/html/install.html#instructions When I make, I get the following error: fatal error: osg/CameraNode: No such file or directory compilation terminated. src/osgviewer/CMakeFiles/osgviewer.dir/build.make:62: recipe for target 'src/osgviewer/CMakeFiles/osgviewer.dir/osgviewer.cpp.o' failed make[2]: *** [src/osgviewer/CMakeFiles/osgviewer.dir/osgviewer.cpp.o] Error 1 CMakeFiles/Makefile2:788: recipe for target 'src/osgviewer/CMakeFiles/osgviewer.dir/all' failed make[1]: *** [src/osgviewer/CMakeFiles/osgviewer.dir/all] Error 2

I'm using trajopt git commit 9c634c060f7e2d61c4a888b0a5700d668a5d16f8. Does anyone know how to solve this error?

My solution:

1. install OSG3.4.0 from source
2. sudo apt-get install libopenscenegraph-dev
3. sudo cp /usr/include/osg/CameraNode usr/local/include/osg/
4. sudo apt-get remove libopenscenegraph-dev
5. build trajopt

I tried to install libopenscenegraph-dev, but I still cannot find CameraNode. What is the version of libopenscenegraph-dev that you installed?

The v1.2 CameraNode object has been renamed to Camera in v2.2. Correspondingly, the signature of several methods that take CameraNode as a parameter or return it as a value were modified to reflect the name change. This impacts any code that uses CameraNode, includes the CameraNode header file, or uses any of the methods that take CameraNode as a parameter or return it as a value.

did you manage to successfully compile with the latest version? If so can you let me know where the changes have to be made? thank you!

Changes I made to compile 

  virtual void operator () (const osg::Camera& camera) const {
    if (!_snapImageOnNextFrame) return;
    int x,y,width,height;
    x = camera.getViewport()->x();
    y = camera.getViewport()->y();
    width = camera.getViewport()->width();
    height = camera.getViewport()->height();
    osg::ref_ptr<osg::Image> image = new osg::Image;
    image->readPixels(x,y,width,height,GL_RGB,GL_UNSIGNED_BYTE);
    // make a local copy
    unsigned char * p = image->data();
    unsigned int numBytes = image->computeNumComponents(image->getPixelFormat());
    _image = std::vector<unsigned char>(p, p + height*width*numBytes / sizeof(unsigned char));
    _height = height;
    _width = width;
    // save file
    if (_filename != "" && osgDB::writeImageFile(*image,_filename))
      std::cout << "Saved screenshot to `"<<_filename<<"`"<< std::endl;
    _snapImageOnNextFrame = false;
  }

however I am still getting an error :
