Issue with shaders compilation for Buttons / Some Editor Buttons are invisible (max/min/Close...) about darkernodes HOT 4 OPEN

It seems that the loading error in Buttons.usf is due to build errors in Shapes.usf.
the #12 line
static float IsInRectangle(float2 Location, float2 Start, float2 End)
in Shapes.usf throws the following error:
error: syntax error, unexpected STATIC

This issue does not occur when using UE 4.27 built on the same system.
So for me, it's a good solution: I'll upgrade the engine version I use
IMO, the code you use in your struct is not compliant with the linux toolchain required for UE 4.25, but it's OK for the 4.27 toolchain.

Wow, sorry for that, that's really weird... If you're ok to update to UE 4.27, it's perfect! If you need to stay on UE 4.25, I'll create a custom shader code for Linux user (as it works as expected on Windows). Keep me posted on!

If you could find a solution for UE 4.25 it could be great, because some other plugins I use are not compatible with 4.27 till now .
I think the issue is due to differences in the C++ versions (and theirs features) allowed in both versions, on linux only because the toolchain used evolves with the engine version.
I can easily compile new plugin code on linux if needed.
I've created a bach script for that. You can find it on my public gitlab
