osgEarthTriton problem : undefined function "float oe_terrain_getElevation();"

[pskpg]

Hi, Glenn!
When I run osgearth_triton.exe with a local bathemetry, cmd shows this:

And the ocean doesn't show as excepted.

The oe_terrain_getElevation is declared in TritonHeightMap.cpp with no implementation, as follows:

How to solve this problem?
Thanks!

Is this causing things to not work, or is it just an annoying message?
I ask because sometimes the shader composition framework will display quirks like this but the code will still work.
The function oe_terrain_getElevation() exists in the SDK shader which should be linked with the shader you are seeing.

Perhaps you missed the step of replacing Triton's "user shaders" with the ones provided with osgEarth? See https://github.com/gwaldron/osgearth/tree/master/src/osgEarthTriton/Shaders and https://www.sundog-soft.com/docs/triton/gettingstarted.html#osgearth

Also be aware you need to build osgEarth from source for Triton integration to work properly; the current osgEarth 3.4 release does not have some important fixes you need.
