Ue5 source code compilation error

0xcdafd0f1 · June 22, 2021, 8:38am

When I compiled the source code of ue5 ea, vs reported the error “\Engine\Source\Runtime\Engine\Classes\Engine/Level.h(805): error C3668: “ULevel::GetWorld”: 包含重写说明符“override”的方法没有重写任何基类方法”.
The error points to the virtual class UWorld* GetWorld() const in Object.h.
This function is in the macro WITH_ENGINE.
So I tried to put the GetWorld function of ActorComponent.h into the WITH_ENGINE macro, and found that the error c3668 of ActorComponent.h disappeared. It seems that the WITH_ENGINE macro is missing from the project.
I am using win10, vs2019 community version. The source code is downloaded from github via sourcetree. bfe798c version.
Here is detail.

Am i missing something ?

You should be using the ue5-early-access branch. Are you? The ue5-main branch is very unstable.

0xcdafd0f1 · June 23, 2021, 12:51am

I am sure I am using the “ue5-early-access” branch.

NachoMonkey2 · June 23, 2021, 12:54am

Hmm… Sorry, I can’t help in that case.

First thing you should try doing is a clean clone of the git.
Reclone it, make sure you have all of the prerequisites listed on the git. From first glance it looks like it’s missing a header file, which can mean either the VS project isn’t properly configured (to point to dependencies) or you really are just missing some files.

Hey man, you are probably like me, a noob haha… I’m guessing this happened after you did a git pull to update the UE5 engine right?

I fixed this exact error by re-running “setup.bat” and “GenerateProjectFiles.bat”, then I could compile again with no problem. I didn’t have to clean solution or anything (luckily, this ■■■■ thing takes forever to compile)

@deitylink1 your suggestion worked for me too. Another thing I would say for future readers is to make sure and check nuget tasks when installing VS, it may not be installed automatically as of right now.

Thank you @deitylink1 and @rsabi for your reminder. Although I had executed Setup.bat and GenerateProjectFiles.bat before the above error occurred, I executed it again.
But the key point this time is that I am using an administrator shell and opened vpn. I can’t remember if I used the administrator shell before, I remember I used it. So this time I think the key lies in my opening vpn.
After I used the administrator shell and turned on vpn, I didn’t see that I had a new update, but it compiled and passed and it ran normally. Thank you both for your replies.
