Problem running example application

Hi,

I built Skybolt using conan and also set SKYBOLT_ASSETS_PATH environment variable correctly. I am getting an error while building

void StateSet::setGlobalDefaults() ShaderPipeline disabled.

when I run any app from Examples.
I used conan to build this.
The exact commands are somehow like this. Apologies I never used conan before, so found all these commands searching online.

pip install conan
conan install . --install-folder C:\Softwares\Skybolt-master\Skybolt-build --build=missing
conan build --install-folder C:\Softwares\Skybolt-master\Skybolt-install --build-folder C:\Softwares\Skybolt-master\Skybolt-build .

IMO I dont think that the above error is the reason for the message void StateSet::setGlobalDefaults() ShaderPipeline disabled. as it appears while building FftOceanTests.exe
Do you know what might be the problem here?

Thanks.

The StateSet::setGlobalDefaults() ShaderPipeline disabled message is information logged by OSG but not an indication of a problem because Skybolt does not use the OSG ShaderPipeline. I'll remove this message in a future version.

Regarding the compilation errors, I wonder if the issue might be related to compiling OSG as a static library. Which compiler version are you using? As a workaround you could try building the shared version of OSG by adding the -o openscenegraph-mr:shared=True argument to conan install.

I also notice you're running conan build with an --install-folder argument which doesn't match your install folder from conan install. You should be able to run conan build without only the build-folder argument, e.g:

conan install . --install-folder C:\Softwares\Skybolt-master\Skybolt-build -o openscenegraph-mr:shared=True --build=missing
conan build C:\Softwares\Skybolt-master\Skybolt-build .

Thank you very much for the help. Its working now. I was able to run the provided examples.
Its working with conan, now I just have to build it using CMake so that I can have more control over everything.
Thanks again for the help. I am closing the issue since its resolved
