No earth file laoded #2913

|
I have built the current version of osgEarth in release and release with debug. No dll conflicts are shown but I cannot get any included application to run other than the version app.. The all say No Earth file loaded. Examples of the the issue is shown below. I add the plugin path to my path as mentioned in other posts but still not help.. J:\SupportLibraries\OsgEarth\bin\relWithDebug>set path=J:\SupportLibraries\OsgEarth\bin\relWithDebug\osgPlugins-3.6.5;%PATH% J:\SupportLibraries\OsgEarth\bin\relWithDebug>osgearth_annotation.exe kml.earth --screen 1 J:\SupportLibraries\OsgEarth\bin\relWithDebug>osgearth_annotation.exe boston_projected.earth --screen 1 Any help would be greatly appreciated. |

I can step into ReadFile.cpp but cannot step into osgDb::readRefNodeFile to see why it returns NULL. It blocks looking for xstring. |

It is highly likely this is a path problem, or that you have multiple DLLs from different build configs (release, relwithdebinfo) in your path. Try using the Dependencies tool to figure out what is missing. |

Glenn:
Thanks for your reply.
The issue seems to be related to earth files. I switched my testing to
osgEarth_map and things work ok. I copied the same dlls I just
used in osgEarth_map to osgEarth_Annotations and have the same problem
originally mentioned.
I did run depends as you suggested but it did not show any errors
I added
_putenv("OSGEARTH_GL_DEBUG=DEBUG");
_putenv("OSGEARTH_NOTIFY_LEVEL=NOTICE");
to osgEarth_annotations and still got a limited error output. Nothing
mentions what is wrong with the earth file

The earth file loader is in a plugin DLL called osgdb_earth.dll that usually lives in a osgPlugins-3.6.5 subfolder under your main bin folder. Copying DLLs around manually is asking for trouble. You will inevitably end up getting mixed versions, mixed configurations, and errors exactly like the one you are seeing. Avoid the suffering. Use the INSTALL target in your CMake projects to install binaries to a known location, and then add that location to your PATH. |

Glenn:
Thanks for the info. That dll was missing from the plugin folder. When
added things work better.
When I run build INSTALL from visual studio it only copies a few of the
total dlls to the install folder. I still have to add the rest but that
file did not make it into the initial plugin folder to get copied.
That leaves two issues, the first of which I remember seeing before but do
not remember the fix. During startup I get an Entry Point Not Found error
from osgdb_zipd.dll but the app continues to load and display correctly.
The other error is not likely related to this one and that but it is not a
show stopper either. During startup I get Fontconfig error: Cannot load
default config file: No such file. That one has been around for a while as
well.
Thanks again

Which DLLs is the INSTALL target not installing? |

Not sure what is intended to be installed. Install/lib only has osgearth(d).lib and osgEarthLmGuil(d).lib. Bin contains the applications and osgEarth(d).dll and osgEarhLmGui(d).dll. installs/bin/osgPlugins-3.6.5 has 23 osgdb_*.dll files. I can send the full list if you want it. We still need to collect all of the osg and gdal files manually. Probably should have used the install directory as my starting point to collect into then I would have had the osgdb_earthd.dll file I was missing. Is any of this related to the osgdb_zipd.dll or fontconfig issue? |

That's right, the osgEarth INSTALL target only installs osgEarth components. You need to add any dependencies to your PATH, or if you are distributing a standalone app, you can create a CMake target to package everything you need. This is outside the scope of osgEarth SDK of course. You can disable building the ZIP plugin with the CMAKE option You can safely ignore the FontConfig message, which comes from OpenSceneGraph. |
