Getting this error trying to compile OnlineSubsystemEOS for Linux

That plugin doesn’t support Linux by default. But you can make a similar plugin in YourProject/Plugins

1. Copy paste the plugin folder (OnlineSubsystemEOS) (eg from C:\Users\JediKnight\Documents\UnrealEngine\Engine\Plugins\Online ) into YourProject/Plugins. Now there you should have a folder named OnlineSubsystemEOS
2. Rename the folder and .uplugin to MyOnlineSubsystemEOS, replace the mentions of OnlineSubsystemEOS to MyOnlineSubsystemEOS in your .uproject and maybe source code (source code – not mandatory?).
3. Create file YourProject\Plugins\MyOnlineSubsystemEOS\Source\OnlineSubsystemEOS\Private\Linux\LinuxEOSHelpers.h with the same content as Mac helpers.
4. Add Linux to PlatformAllowList of 2 modules in .uplugin
5. Now this should compile
