In the GitHub UnrealEngine-5.5.0-release version, the UBA executables located in:
Engine\Binaries\Win64\UnrealBuildAccelerator\x64\
are downloaded via Setup.bat.
However, when I compile them manually using:
Engine\Source\Programs\UnrealBuildAccelerator\Deploy-Windows.bat,
the resulting executables differ from the pre-downloaded ones.
Questions:
- How are the original (pre-downloaded) UBA executables generated?
- Are they compiled from the same source code in
UnrealEngine-5.5.0-release? - Or are they built from a different version of the source?
- What is the correct way to compile UBA from source to match the pre-built executables?
- Am I missing a build step or configuration?
- Are there additional flags or optimizations used in the official build process?
Additional Details:
- I’ve verified that the source files match the GitHub release tag.
- The differences include file size, timestamps, and possibly optimizations.
Could someone clarify the official build process for these binaries?
Thanks in advance!
