UE5.3 Issue

[vincentlincoln]

Hi, I am new with cosys airsim, and i have an issue with UE5.3.2. I followed the install tutorial on https://cosys-lab.github.io/unreal_custenv/#unreal-5354-scene-camera-bug

I have theses warnings too:

Does it supports 5.3.2? It works fine on 5.4.

Are you using from source or the prebuilt plugins? The prebuilt plugin from the releases page only supports 5.4.

If you are using from source you should use the 5.3 branch as that one should work better for Unreal 5.3

I used from source, I also tried to use the 5.3 branch with a git checkout but i got a lot of C++ errors on VS.

Strange, I just did a fresh checkout of the 5.3 branch with Unreal 5.3.2 and got a working Blocks environment without any build errors. Following these steps

Visual Studio 2022 14.41.34120
Windows 10.0.22621.0 SDK
DotNet SDK version: 6.0.302

We made a small update and new release, I pushed the same changes and fixes to the 5.2 and 5.3 branches.

I did another clean install and did not run into any problems again.

• Unreal 5.3.2
• CMake 3.24.2
• Visual Studio 22 (17.11.4)
• MSVC 19.41.34120.0
• Windows SDK version 10.0.22621.0

I did however have an issue with building the RPC library while running the build.cmd script. It gave me fatal error C1090: PDB API call failed, error code '3'. The reason was related to my Dropbox client running in the background and causing a compile error. So I would suggest to always close programs like Dropbox, Google Drive, Onedrive, IDEs and other file checking systems while running the build.cmd script. Could you try to run the build.cmd script again and see if you run into any errors there? Make sure to run clean.cmd first and see that the following folders are gone to trigger a proper rebuild:

• external
• AirLib/deps
• AirLib/lib/*
• Airlib/temp
• Unreal/Plugins/AirSim/AirLib
• Unreal/Environments/YOURENVIRONMENT/Plugins
• Unreal/Environments/YOURENVIRONMENT/DerivedDataCache
• Unreal/Environments/YOURENVIRONMENT/Intermediate

and make sure build.cmd completes without errors.

Thank you for your help. Last week i tried with 5.2 and it works well. (I didn't retry with 5.3)

Given #36 is similar I will close this issue and keep track of the other one for 5.3 build and compile problems.
