When I build the CitySample using UE5.0.3 source build I first get this build time errror:
Module.ElectraPlayerPlugin.cpp.obj : error LNK2019: unresolved external symbol "public: void __cdecl FElectraTextureSample::Initialize(class FVideoDecoderOutput *)" (?Initialize@FElectraTextureSample@@QEAAXPEAVFVideoDecoderOutput@@@Z) referenced in function "public: virtual void __cdecl
Which I am able to work around by disabling the default addition of ElectraPlayer plugins in CitySample.Build.cs with Target.Type != TargetType.Server on line 93:
if(Target.Platform != UnrealTargetPlatform.Linux && Target.Type != TargetType.Server)
{
PrivateDependencyModuleNames.AddRange(new string[]
{
"ElectraPlayerRuntime",
"ElectraPlayerPlugin"
});
}
The dedicated server build succeeds. However when I run .\CitySampleServer.exe -log I get a series of warnings complaining about SoundscapeSubsystem, WorldAudioDataSubsystem, MassTrafficSubsystem, but ultimately ending with the below error that crashes the executable:
