Error while trying to generate vs project files for dedicated server

Hello,

This is the error I am receiving:

"Messages while compiling C:\Users\Documents\Unreal Projects\myproject\Intermediate\Build\BuildRules\myprojectModuleRules.dll:
C:\Users\Documents\Unreal Projects\myproject\Source\myprojectServer.Target.cs(6,14) : error CS0101: The namespace ‘’ already contains a definition for ‘myprojectServerTarget’ "

Windows 10 Pro

Unreal 4.17.2

Visual Studio Community 2017

These are the files I am working with…

myproject.Target.cs

using UnrealBuildTool;
using System.Collections.Generic;

[SupportedPlatforms(UnrealPlatformClass.Server)]
public class myprojectServerTarget : TargetRules  
{
       public myprojectServerTarget(TargetInfo Target) : base(Target) 
       {
        Type = TargetType.Server;
        ExtraModuleNames.Add("myproject");   
       }
}

myprojectServer.Target.cs

using UnrealBuildTool;
using System.Collections.Generic;

public class myprojectServerTarget : TargetRules
{
      public myprojectServerTarget(TargetInfo Target)
      {
         Type = myprojectServerTarget.Server;
         bUsesSteam = true;
      }

       //
       // TargetRules interface.
       //

       public override bool GetSupportedPlatforms(ref List<UnrealTargetPlatform> OutPlatforms)
       {
            // It is valid for only server platforms
            return UnrealBuildTool.UnrealBuildTool.GetAllServerPlatforms(ref OutPlatforms, false);
       }

       public override void SetupBinaries
       (
          TargetInfo Target, ref List<UEBuildBinaryConfiguration> OutBuildBinaryConfigurations,
          ref List<string> OutExtraModuleNames
       )
       {
         OutExtraModuleNames.Add("myproject");
       }
}

I am having been trying to figure this out for awhile. Scoured google and the forums and, while others seem to have similar problems, I don't think I've made the exact mistakes (who knows). Any help would be greatly appreciated.

Thanks!

The *.Target.cs file shouldn’t define the server target. That should just be in the *Server.Target.cs file. The *.Target.cs file is for the non-server target, aka the standard game target (for standalone and client games). The Editor.Target.cs file has its own too. The main difference is in the “Type =” statement. You need those to match the file names, TargetType.Server with *Server.Target.cs and so on.

I think what’s happening is you have the server target defined in both cs files. If you can simply restore the *.Target.cs file to what it was before you changed it, then that would be the quickest fix. Or copy the one generated for a template project.

So basically, you want myproject.Target.cs to declare myprojectTarget instead of myprojectServerTarget – and change “Type = TargetType.Server;” to “Type = TargetType.Game;”.

Thank you for responding!

I made the changes that you described above. Your explanation made a lot of sense. Now I am getting a different error. Progress! :slight_smile:

warning CS0618: ‘UnrealBuildTool.TargetRules.TargetRules()’ is obsolete: ‘Please pass the TargetInfo parameter to the base class constructor (eg. “MyTargetRules(TargetInfo Target) : base(Target)”).’

myprojectServerTarget.cs

    using UnrealBuildTool;
        using System.Collections.Generic;
        
        public class myprojectServerTarget : TargetRules

              }
        
               //

               //
        
               public override bool GetSupportedPlatforms(ref List<UnrealTargetPlatform> OutPlatforms)
               {
                    // It is valid for only server platforms
                    return UnrealBuildTool.UnrealBuildTool.GetAllServerPlatforms(ref OutPlatforms, false);
               }
        
               public override void SetupBinaries
               (
                  TargetInfo Target, ref List<UEBuildBinaryConfiguration> OutBuildBinaryConfigurations,
                  ref List<string> OutExtraModuleNames
               )
               {
                 OutExtraModuleNames.Add("myproject");
               }
        }

Is this maybe because the code in the Server.Target.cs does not work for my version of Unreal?

Thanks again!

I fixed it!

If anyone else is having this problem here is what I did. The target.cs file remained the same but I changed the servertarget.cs file so it basically mirrored the syntax and structure of the target.cs file. The code I was trying to use is obsolete for 4.17.2

Thanks for the help.
