This might be a path issue on Windows. I'd start by including the paths to where vcpkg is installing dlls and plugins to your PATH env variable

path\vcpkg_installed\x64-windows\bin path\vcpkg_installed\x64-windows\plugins\osgPlugins-3.6.5

vcpkg is great for the build but you need to deal with finding all the files and making sure they are in your path

No it is not path issue, path is set, same I tried on ubuntu22 as well same error is coming, it is not proceeding ahead. :(

On Ubuntu, you wouldn't need vcpkg, just apt-get dependencies such as: 1 Build essentials sudo apt update && sudo apt install build-essential

2 GDAL: sudo apt-get install libgdal-dev

3 GLEW sudo apt-get install libglew-dev

4 Build Openscenegraph git clone https://github.com/openscenegraph/OpenSceneGraph.git cd osg mkdir build && cd build cmake .. make -j8 sudo make install

6 Build osgEarth git clone https://github.com/gwaldron/osgearth.git cd osgEarth mkdir build && cd build cmake .. make -j8 sudo make install

Are running "osgearth_viewer simple.earth" ?

[plevy]

I just tested it again and I would be surprised if the build was successful and the path was not an issue. As I said, make sure you are specifying a valid .earth file from the tests folder on the command line

i have added libopengl.so while linking, and now it is working. thanks plevy :)

Hello, I have also encountered such a problem, may I ask what specific documents you have added to solve this problem

[plevy]

The previous problem was linking to libopengl. What is your specific problem? When you run "osgearth_viewer simple.earth" does it exit immediately which is probably a dll not in your path problem or if there is output from the command, post it here

I tried to copy the files in this path（\osgearth\osgearth-osgearth-3.2\src\applications\osgearth_viewer） to run in VS, but the following error occurred [osgEarth]* [MapNodeHelper] No valid earth file loaded - aborting [osgEarth] Usage: D:\Code\VS Code\osgearth\osgearth\x64\Release\osgearth.exe file.earth --sky : add a sky model --kml <file.kml> : load a KML or KMZ file --kmlui : display a UI for toggling nodes loaded with --kml --coords : display map coords under mouse --ortho : use an orthographic camera --logdepth : activates the logarithmic depth buffer --logdepth2 : activates logarithmic depth buffer with per-fragment interpolation --shadows : activates model layer shadows --out-earth [file] : write the loaded map to an earth file --uniform [name] [min] [max] : create a uniform controller with min/max values --define [name] : install a shader #define --path [file] : load and playback an animation path --extension [name] : loads a named extension --ocean : add a simple ocean model (requires bathymetry)
