Compiling Failed while Upgrading Projects

Development Programming & Scripting

So I am trying to take a project (Project FreeFall for those of you who have heard of it) and upgrade it from 4.4 into 4.8 but when I try to do so it comes back with a screen that says Compile Failed and then asks if I want to open it in Visual Studio. This is what the window displays:

Then when I go and rebuild the solution in VS it comes back as succeeded. BUT it still returns this window when I try to open it in UE4.8.

Hey ShadowGhost2-

There have been a number of code changes between 4.4 and 4.8 (namely in 4.7 and 4.8). It’s possible that some of the code in the project isn’t compatible with the changes made in the engine. I would start by upgrading the project through each engine version (4.5,4.6,4.7,4.8) and compile each time you move to a new version. This will give you the chance to see if any of the code has been depreciated or needs to be updated.

Cheers

Just recently the guy who created Project FreeFall upgraded is source code/content to 4.6 and he said that he is working on getting them to 4.7 and 4.8 but thanks for the idea about moving slowly up the version ladder.

I’ve been trying to upgrade from 4.7 to 4.9 for 2 days and how extremely difficult it’s being
