unreal 5.3.2 airsim problem

[ZivniR]

hello,

when i built the game with 5.3.2 cosys-AirSim version the blocks worked perfectly open game and run

but when i try to use on my own project i get errors in Eigen every time like if i take an old version which suitable for 5.2 and add this plug in to the project. (the unreal-editor didnt open)

i try to use 5.4 it open the editor but cant run because of the other issue there was open here.

could you give me an suggestion what i am doing wrong?

thank you very much!

You are building the plugin from source right? As we dont have a prebuilt version for 5.3.

Can you post the exact error you get?

Can you check if your uproject file is similar to the one used in Blocks?

Follow the guide here for the step-by-step guide for custom environments.

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 a clean install and did not run into any problems.

• 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.
