^{Originally posted by keince March 23, 2022} I pulled the latest osgearth master into my local repo and rebuilt the solution.

Now I'm getting the following errors during runtime...

Any idea what is causing these runtime errors?

Curious, I'm not seeing any such errors. Do you have any env vars set?

@keince Are you still experiencing this? Pull latest master and re-run osgearth_version --caps please.

I'm seeing these errors as well on running the latest master.

I'm building with vcpkg on Windows and Visual Studio 2017. I'm also not building OpenSceneGraph explicitly which is built in vcpkg.

If memory serves, this has to do with CMake settings and turning off certain CMake variables for OpenSceneGraph and how shaders are used. Since I'm using vcpkg, not sure how to do this in the OSG.

Here's a discussion that is probably related to this problem... https://github.com/gwaldron/osgearth/issues/1227

Try grabbing the master osgearth and seeing if that fixes your issue. The issue is that the vcpkg osg isn't built with GL3 enabled. I'm working on a patch for that here: https://github.com/microsoft/vcpkg/pull/24026 In the meantime I added a change to osgearth that should get you up and running with the vcpkg version of osg.

Thanks Jason. I'll give it a try...

Thank you Jason.

So...I pulled master today and rebuilt. It runs without the aforementioned shader errors but now I'm seeing a different problem.

When I run osgearth_viewer annotation.earth it displays the readymap earth and annotations for a second and then quits for no reason. All other earth files load and run fine.

There are no reported errors on the console with OSGEARTH_NOTIFY_LEVEL=INFO set.

Same things happens to me. I try to run osgearth_annotations example and it shows up. After 1-2 seconds, it quits with no reason.

Ok, I managed to build OSG with GL3 support and then build the master branch osgearth successfully. Everything seems to work fine. But I get shaderpipline disabled message on the console as below. By the way, I do not have any idea why the "Fontconfig error" started to show up. The font path seems correct. I know this is an osg question. But there is no answer to the question in osg forum. Any ideas?

GL3: Non-GL3 version number: 1.0 void StateSet::setGlobalDefaults() ShaderPipeline disabled.

Here is the version output: Fontconfig error: Cannot load default config file: No such file: (null) Error reading file C:/WINDOWS/fonts\mingliub.ttc: file not handled GL3: Non-GL3 version number: 1.0 [osgEarth] [Capabilities] Capabilities: [osgEarth] [Capabilities] osgEarth Version: 3.2.0 build 132 [osgEarth] [Capabilities] OSG Version: 3.7.0 [osgEarth] [Capabilities] GDAL Version: 3.4.1 [osgEarth] [Capabilities] GEOS Version: 3.10.0 [osgEarth] [Capabilities] GPU Vendor: Intel [osgEarth] [Capabilities] GPU Renderer: Intel(R) UHD Graphics [osgEarth] [Capabilities] GL/Driver Version: 4.6.0 - Build 30.0.101.1122 (460) [osgEarth] [Capabilities] GL Core Profile: no

Apr 09 '22 09:04 nebsar

I tried other examples and some of them do not work properly because of the shader errors. Below message is from osgearth_bindless example:

osgearth_picker example has the weird behaviour as in the video.

Are you trying to run with --nvgl or --gl4? I'm surprised that you're seeing osgEarth try to go down the NVGL Nvidia only GL path on an Intel graphics card.

Apr 09 '22 20:04 jasonbeverage

I am not adding any additional arguments other than the earth file and for some examples --sky while running the examples.

Apr 10 '22 02:04 nebsar

After some research, I come up with the conclusion that, when OSG version 3.7.0 is built against GL3, "ShaderPipeline disabled" problem occurs. And most probably, this yields other shader errors. But I am still not sure. I applied everything in this discussion #1227 while building OSG 3.7.0 (master branch). But it did not help.

By the way, while building OSG from source, if OSG_TEXT_USE_FONTCONFIG is unchecked, "Fontconfig error: Cannot load default config file: No such file: (null)" error goes away.

Apr 10 '22 05:04 nebsar

The osgearth_bindless example requires an NVIDIA card. I have updated the example to reflect this.

Apr 11 '22 12:04 gwaldron

The ShaderPipeline disabled message is probably not an issue. This is a new feature OSG added to let the user customize the default shaders; osgEarth does not make sure of it.

What new shader errors are you getting with your GL3 build?

Apr 11 '22 12:04 gwaldron

I've also pushed an update that attempts to detect the int64 extension availability -- you may be getting errors because the ShaderFactory was automatically trying to use this extension. Please grab an update and try again.

And thanks for your continued feedback -- we don't have an Intel GPU to test on atm so this is helpful.

Apr 11 '22 13:04 gwaldron

Yes Glenn. I am getting the new shader errors with GL3 build. osgearh_picker example's weird behaviour is also on GL3 build. I will try to run the examples with Nvidia as well. And no problem, as osgEarth has more capabilities with minimum bugs, this will also help me. Thanks.

Apr 11 '22 13:04 nebsar

If you continue to get shader errors on Intel GPU (with the latest pushes) please post them here. Please use a basic setup (like osgearth_viewer simple.earth) for baseline testing.

Apr 11 '22 14:04 gwaldron

Ok I will.

Apr 11 '22 15:04 nebsar

Here are the latest shader errors and osgEarth configuration info with GL3 built, when I run osgearth_viewer.exe with annotation.earth:

I think this because when the osg is built with default functions OFF. And Intel HD does not support some shaders. You may see the GL config screenshot while I built the OSG with Cmake GUI in windows.

Apr 13 '22 15:04 nebsar

Another note: If the OSG_GL_CONTEXT_VERSION is set to 3.0 beside the OPENGL_PROFILE as GL3, "GL3: Non-GL3 version number: 1.0" message on the command prompt goes away.

Apr 13 '22 15:04 nebsar

Try setting your OSG_GL_CONTEXT_VERSION to 3.3, not sure where the 3.0 came from, did you manually set that?

When you build osg you really shouldn't need to set any of those build variables yourself. You should try building osg from the command line and pass in -DOPENGL_PROFILE=GL3 instead. I've got a vcpkg PR out that should hopefully make this easier in the future (https://github.com/microsoft/vcpkg/pull/24108).

You can also try setting the context version via an env var with set OSG_GL_CONTEXT_VERSION=3.3 or set OSG_GL_CONTEXT_VERSION=4.6

Apr 13 '22 15:04 jasonbeverage

Ok I will do that

Apr 13 '22 15:04 nebsar

I build OSG from source to include some additional plugins such as fbx, ffmpeg

Apr 13 '22 15:04 nebsar

Ok. Here is the capabilities info after building the OSG with OSG_GL_CONTEXT_VERSION=3.3. There are no shader errors anymore. But when I run the osgearth_viewer example with boston.earth and when the camera gets close to the Boston city and the buildings started to load, I get the following warning repeatedly:

Warning: detected OpenGL error 'invalid enumerant' at after RenderBin::draw(..)
