Hi Julian,

Here’s what I did:

  • checkout branch 5.6 from Unreal’s github (ue5-main fails in GitDependencies due to invalid compression)
  • generate Uba.sln and compile it in Debug, copy the binaries to my test bed
  • run Build.bat BlankProgram Development Win64
    • the full build completes successfully
  • touch BlankProgram.cpp to trigger a recompile
  • run Build.bat BlankProgram Development Win64 -UbaLog
    • the build fails with the infamous LINK : fatal error LNK1168: cannot open ..\Binaries\Win64\BlankProgram.exe for writing

See the attached log, which mentions the error.

We don’t use symlinks in our source setup.
