Bull Cows game project can not compile, Unreal Engine 4.25

ytsrd · May 15, 2020, 12:46am

I tried to open the Bull Cows Game project file in UE4Editor and got a message to convert the project for Unreal Engine version 4.25(I am using ver 4.25), then I got this error log:

The project could not be compiled. Would you like to open it in Null Source Code Access?

Could I have some tips?

ps: I tried to open the project after the failed conversion, and the project won’t open in the UE4Editor, I got the following log in my terminal:

They mention at the start of the tutorial that you should be on Unreal 4.22.3, otherwise it could cause some issues. I would recommend downloading the version 4.22 and seeing if that helps.

Use the code-workspace to compile. Open that with VS Code and then Ctrl + Shift + B then choose Linux DevelopmentEditor Build

thanks so much, it worked

ytsrd · May 15, 2020, 1:51pm

Hey thanks for the tip, yes I had some problems installing 4.22 with git clone https, so I switched to ssh but forgot to add the branch i think i will just stick to 4.25 for a bit and see how it goes
