Build Error after upgrading new engine version

Kamo267 · May 24, 2023, 11:56am

Hey everyone! I get failed build after upgrading LyraStarterGame migrated project from 5.0.3 to 5.1.1.

I followed the instructions to do after upgrading (Remove the required folders and “Generated Visual Studio Project Files”) and now when I open the new created .sln file and try to build I get failed build with these messages:

Hi there,
I few code references have changed in UE5.1 c++ API, and old references are now deprecated.

Kamo267:

1>DEPRECATION: ‘IniKeyBlacklist’, which is a config key in section [/Script/UnrealEd.ProjectPackagingSettings], in ‘K:\Projects\UglyBros\LyraMergeVerse2V2 5.1\Config\DefaultGame.ini’, has been deprecated.

Using ‘AllowedDirectories’ instead. It is recommended you update your .ini files as soon as possible, and replace WhitelistDirectories with AllowedDirectories

Open DefaultGame.ini (either via Windows Explorer or Visual Studio), and find references (in the open document):

IniKeyBlacklist and replace all references by IniKeyDenylist
IniSectionBlacklist and replace all references by IniSectionDenylist
WhitelistDirectories and replace all references by AllowedDirectories

You have to close all open projects, otherwise you’ll get this error.

Hope that helps.

Thank you for the answer! I did just what you told. This time I got this messages and build failed again:

This is part of c++ API changes and it’s not straight forward. You have to fix one by one. Sometimes, you have to add a declaration “include …” at the top of a object, or “#pragma once”, also change the reference of pointers (FWeakObjectPtr).

There is an official release notes that how to reference properly in 5.1 (Upgrading the Lyra Starter Game to the Latest Engine Release in Unreal Engine | Unreal Engine 5.1 Documentation)

Another way to help with your fixes is creating as Lyra Project 5.1 and comparing object by object and see how the lines were changed.

Also, check the Lyra Discord Channel (Lyra Dev Net), If I’m not wrong, there’s a post with detailed instructions. Hope that helps.

Sounds like a sensible approach! Gonna try it out. Thank you so much!

I get a successful build now, but editor crashes when I try to open the project:

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\DeveloperSettings\Private\Engine\DeveloperSettings.cpp] [Line: 132] LyraDeveloperSettings failed to find console variable LyraPC.ShouldAlwaysPlayForceFeedback for bShouldAlwaysPlayForceFeedback

This one is related to the Engine API. You’ve narrowed down to three objects:
DeveloperSettings.cpp (Engine)
LyraDeveloperSettings.h (Lyra)
LyraDeveloperSettings.cpp (Lyra)

If you compare two Lyra projects, 5 and 5.1, go to LyraDeveloperSettings.cpp and check how that console variable is now referenced in 5.1. More Likely, you’ll probably need to add:

“#include UE_INLINE_GENERATED_CPP_BY_NAME(LyraDeveloperSettings)” at the top of LyraDeveloperSettings.cpp. Should be like this in 5.1:

#include “LyraDeveloperSettings.h”
#include “Misc/App.h”
#include “Widgets/Notifications/SNotificationList.h”
#include “Framework/Notifications/NotificationManager.h”

#include UE_INLINE_GENERATED_CPP_BY_NAME(LyraDeveloperSettings)

In addition, that console variable has been changed and you want to find the correct reference. Check if that var is an input in your project settings (compare 5 and 5.1).

Well I copied all the scripts from created LyraGame project with 5.1 and I broke it. So started with a new project and I minimize the errors to this:

Thanks again!

Have you copied and pasted the line 36? It can cause problems if one of the variables have definition in the correspondent cpp file. Looks like you are missing the definition of “GetPreloadAssetListForGameFeature” because it is marked in red. Right click on it, select peek definition to see if it still exists and is incomplete:

Should look like this in the LyraGameFeaturePolicy.cpp:

If no existent, right click, select “Quick Actions and refactorings…”,

then select create definition to open a blank definition template in the cpp file. So add the following line:

return Super::GetPreloadAssetListForGameFeature(GameFeatureToLoad);

Hope that helps.

Yes I added it from lyra 5.1 project. And seems I got the definition but it’s marked red too.

This is a correct VS procedure:
delete GetPreloadAssetListForGameFeature and type in “getpreload”, a list of existing references should appear, then select the correct one.

No red marks now but I get a new error. I’m not sure if it’s related to the same line.

Typically, unresolved external symbol means you’re missing the link of additional library dependencies (paths). First place to check is looking at LyraGame.Build.cs and compare both versions. I’ll see if I can find something helpful.

Verifying UE 5.1 engine files fixed the issue for me. Thanks for sparing time, much appreciated.
