LiveCoding fails to link when Radlinker is enabled

Hello,

When radlink.exe usage is enabled, LiveCoding consistently fails to succeed. It fails on linking step with error below.

...
Could not find image section containing dynamic initializers.
This will lead to constructors of global and static variables being called again for the next patch, likely leading to unexpected behaviour.
UbaCli v5.8.0-Uba_v1.0.0-50760079 (Rootdir: "C:\ProgramData\Epic\UbaCli", StoreCapacity: 0Gb)
 
---- Starting trace: Debug436ce144-ee6a-4cca-b496-07b7eef52ae5 ----
Running F:\proj\UE5Main\Engine\Binaries\Win64\RadDebugger\x64\radlink.exe @C:\Users\<user>\AppData\Local\Temp\6C15.tmp
Error(002): unknown file format " ■"
Error exit code: 2
Failed to link patch (0.000s) (Exit code: 0xFFFFFFFF)
---------- Finished (0.000s) ----------

This is reproduced both in UE 5.6.1 as well as on the current latest //UE5/Main revision: CL50765067 in Lyra game sample. Is there any known fix or workaround for this issue? Or is Radlinker currently not in a stage where it can be utilized in environments that incorporate use of LiveCoding?

Best regards

Steps to Reproduce

  1. In any project, enable Radlinker, e.g. by adding line WindowsPlatform.bAllowRadLinker = true; to <Project>Editor.Target.cs.
  2. Run editor, recompile if necessary.
  3. Make a change to project’s source code, e.g. by adding a line in a .cpp file.
  4. Run LiveCoding in editor.
  5. Observe an error during linking.

Hi,

Thanks for reporting. This is a known issue (UE-230373), currently backlogged. I don’t expect this issue to be addressed in a short term, maybe not even mid-term. For a foreseeable time, you will have to pick either LiveCoding or RadLinker.

Regards,

Patrick
