Missing Gameframework when Compiling

Development Programming & Scripting
,
1

Hi, I’ve switched to Linux this year and have been trying to set up my Unreal project today. I’ve managed to get Unreal Engine installed and the editor starts as expected. Now I’m trying to compile my project from Rider because the editor can’t compile or open it and asks me to have it compiled in an IDE.

I’m using
Arch Linux
Unreal Engine 5.3 (compiled from source)
Rider 2026.1.2 (from AUR)

I’ve worked through Rider Setup Guid where I can:

  • Installed Rider
  • Didn’t install EzArgs plugin because I didn’t use it even when I was on Windows
  • Didn’t apply the RAM settings because I don’t have 64 GB RAM (worked just fine on Windows)
  • I have dotnet and MSBuild set up

Now to my actual problem: I’ve opened the uproject file with Rider and loaded the project. I click on Build Startup Project and let the project compile. I get a bunch of errors in Build Output. The most obvious issue is that Rider is unable to resolve Gameframework in includes.

The build output says this:

Some of the build errors make sense, like the missing Gameframework path in the include. Others seem to be fine:

0>ControllerReadyUserWidget.h(31,58): Error  : unknown type name 'UInputDeviceSubsystem'
0>        bool IsGamepad(const FInputDeviceId& InputDevice, const UInputDeviceSubsystem* SysPtr) const noexcept;

I know Linux support isn’t exactly great for Unreal Engine, but it seems like I’ve already got over the hard part, but I don’t know what the issue is here. I would like to figure out how to resolve Gameframework first and see if I’m able to compile again after that. What do I have to do to fix this?
