I saw some mail threads about it awhile back and have looked at this https://tianocore-docs.github.io/edk2-BuildSpecification/release-1.28/12_bu= ild_changes_and_customizations/126_build_reproducibility.html#126-build-rep= roducibility, which seems to claim that you can just do a RELEASE build with MDEPKG_NDEBUG set and get binary compatible builds. However, when attempting that with a clean OVMF IA32X64 VS2022 RELEASE build at the same commit (and rebuilt basetools), I am getting significantly different FDs and FVs. The driver files are almost identical except for what I am assuming is a build identifier or timestamp. Are there any additional resources or thoughts towards complete binary reproducible builds? Thanks, Oliver -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D- Groups.io Links: You receive all messages sent to this group.
