[mhe1999]

Bug report

• Colosseum Version/#commit: Latest commit
• UE/Unity version: Unreal Engine 5.3.2(as i see you recommended in some of your documents)
• autopilot version: N/A
• OS Version: Windows 11
• VS version: Fresh installation of VS2022 community version 17.10.5 as the only VS on my system
• SDK versions installed with the VS2022: windows 10 SDKs(10.0.18362, 10.0.19041, 10.0.20348), and windows11 SDKs(10.0.22000, 10.0.22621, 10.0.26100)

What's the issue you encountered?

I am encountering several issues while trying to build and run the Colosseum project on Unreal Engine 5.3.2 on my Windows 11 system. Below are the steps I followed and the errors I encountered:

1. Cloning Colosseum:

   • Used Developer Command Prompt in Visual Studio to clone the latest commit of Colosseum.
   • Command used: git clone https://github.com/CodexLabsLLC/Colosseum.git
   • Ran git submodule update --init. (the built wasn’t successful without it, the build output suggested that i update the submodules)

2. Building Colosseum:

   • Ran the build.cmd script.
   • During the build process, encountered the following errors:

     BlocksV2.Target.cs(11,47): error CS0117: 'BuildSettingsVersion' does not contain a definition for 'V5'
     BlocksV2.Target.cs(12,51): error CS0117: 'EngineIncludeOrderVersion' does not contain a definition for 'Unreal5_4'
     BlocksV2Editor.Target.cs(11,47): error CS0117: 'BuildSettingsVersion' does not contain a definition for 'V5'
     BlocksV2Editor.Target.cs(12,51): error CS0117: 'EngineIncludeOrderVersion' does not contain a definition for 'Unreal5_4'
     

3. Attempted Fix:

   • Changed BuildSettingsVersion.V5 to BuildSettingsVersion.Latest and EngineIncludeOrderVersion.Unreal5_4 to EngineIncludeOrderVersion.Latest in the BlocksV2.Target.cs and BlocksV2Editor.Target.cs files.
   • This allowed the build process to complete without errors.

4. Further Steps Taken:

   • Ran clean_rebuild.bat.
   • Set 'Visual Studio 2022' as the 'Source Code Editor' in Unreal Engine.
   • Right-clicked on BlocksV2.uproject and selected 'Generate Visual Studio project files'.
   • Opened the BlocksV2.sln file in Visual Studio, set BlocksV2 as the startup project, and ran the project.

5. Encountered Build Errors:

   • Received the following errors:

     error LNK2019: unresolved external symbol _Thrd_sleep_for referenced in function "void __cdecl std::this_thread::sleep_for<__int64,struct std::ratio<1,1000> >(class std::chrono::duration<__int64,struct std::ratio<1,1000> > const &)" (??$sleep_for@_JU?$ratio@$00$0DOI@@std@@@this_thread@std@@YAXAEBV?$duration@_JU?$ratio@$00$0DOI@@std@@@chrono@1@@Z)

     ========== Build: 0 succeeded, 1 failed, 10 up-to-date, 0 skipped ==========
     ========== Build completed at 11:02 AM and took 01.531 seconds ==========
     

6. Popup Messages:

   • Selected 'Yes' on the popup(“there were build errors, would you like to continue and run the last successful build”) to rebuild the project.
   • Encountered the error: "BlocksV2 could not be compiled. Try rebuilding from source manually."
   • Same issue when opening the BlocksV2 project using Unreal Engine 5.3.2, instead of opening with VS2022, with the message: "The following modules are missing or built with a different engine version: BlocksV2, AirSim. Would you like to rebuild them now?" Selecting 'Yes' results in the same "BlocksV2 could not be compiled, Try rebuilding from source manually." error.

7. Additional Information:

   • Installed .NET versions on my system are 6.0.424 and 8.0.303.
   • Unreal Engine works perfectly with other projects, including those using blueprints and C++ files.
   • Tried creating a new project and adding the Colosseum plugin (including updating uproject and DefaultGame.ini), but encountered the same issues.

Heya,

I updated the version to Unreal 5.4, so just use a different engine version and it should work

Heya,

Thanks a lot. To my surprise, it did the trick. @JulianDev24

@mhe1999 It didn't work for me even for 5.4. Can you please share which branch of coloseum you used or any specific changes you made?

[mhe1999]

@DeepChavan30
I’ve been using the main branch and haven’t made any changes related to building. Are you encountering the exact same errors as I did? you can share more details about the specific errors and the versions you’re using.

Thanxs @mhe1999
It worked after i made some changes in .uproject and build it from source using visual studio. But causes error while cross compiling for linux os. Changes made in .uproject are
initially:

{
	"FileVersion": 3,
	"EngineAssociation": "5.4",
	"Category": "",
	"Description": "",
	"Modules": [
		{
			"Name": "MyProject",
			"Type": "Runtime",
			"LoadingPhase": "Default",
			"AdditionalDependencies": [
                		"AirSim"
            		]

		}
	],
	"Plugins": [
		{
            		"Name": "AirSim",
            		"Enabled": true
        	},
        	{
            		"Name": "ModelingToolsEditorMode",
            		"Enabled": true,
            		"TargetAllowList": [
                		"Editor"
            		]
        	}

	]
}

After changes

}

@DeepChavan30,
I tried your JSON file on Windows, and it worked without any issues. I don’t have experience with Linux for this project, so I’m unable to recreate your problem.

Can we close this?

[DeepChavan30]

Yes

Tried the 5.4 engine from the built versions of 5.2 (main) and 5.3 (branch). When I click Blocksv2 it loads on 5.4 but then I get this error at 75%
