GL3: Non-GL3 version number: 1.0 and Core Profile = no

Hi! I compile osg 3.6.4 and osgearth 2.10.1 with GL CORE according the instructions:
https://gist.github.com/gwaldron/a56b0e77e7fa8587b698717d21f9366d .
After I finish compiling, run "osgearth_version --caps", shows:

osgEarth Library 2.10.1

GL3: Non-GL3 version number: 1.0
[osgEarth]  [Capabilities] osgEarth Version: 2.10.1
[osgEarth]  [Capabilities] OSG Version:      3.6.4
[osgEarth]  [Capabilities] GDAL Version:     2.1.1
[osgEarth]  [Capabilities] Detected hardware capabilities:
[osgEarth]  [Capabilities]   Vendor = Intel
[osgEarth]  [Capabilities]   Renderer = Intel(R) HD Graphics 520
[osgEarth]  [Capabilities]   Version = 4.6.0 - Build 26.20.100.6913
[osgEarth]  [Capabilities]   Core Profile = no
[osgEarth]  [Capabilities]   Max GPU texture units = 32
[osgEarth]  [Capabilities]   Max GPU texture coord indices = 8
[osgEarth]  [Capabilities]   Max GPU attributes = 16
[osgEarth]  [Capabilities]   Max texture size = 16384
[osgEarth]  [Capabilities]   GLSL = yes
[osgEarth]  [Capabilities]   GLSL Version = 460
[osgEarth]  [Capabilities]   Texture arrays = yes
[osgEarth]  [Capabilities]   draw instanced = yes
[osgEarth]  [Capabilities]   Texture buffers = yes
[osgEarth]  [Capabilities]   Texture buffer max size = 134217728
[osgEarth]  [Capabilities]   Compression = ARB S3

My question is what does "GL3: Non-GL3 version number: 1.0" and "Core Profile = no" mean actually?
Can anyone give me a direction how to fix these issues?

Re: GL3: Non-GL3 version number: 1.0 and Core Profile = no

Try setting the env var OSG_NOTIFY_LEVEL=INFO and running again. See what OSG prints when trying to create the graphics context.

Re: GL3: Non-GL3 version number: 1.0 and Core Profile = no

Problem:

GL3: Attempting to create OpenGL3 context.
GL3: version: 1.0
GL3: context flags: 0
GL3: profile: 0
GL3: Non-GL3 version number: 1.0
GL3: context created successfully.

Try these env vars:

set OSG_GL_CONTEXT_VERSION=3.3

set OSG_GL_CONTEXT_PROFILE_MASK=1

(Setting the profile mask to 1 requests a CORE context.)

Great.
On my system (NVIDIA) it is selected automatically. Not sure why not on yours!
