The build-info package rebuilds every time, as it generates the /etc/build-info file with info about the build. You can skip this by using “build-pkgs --no-build-info”. SM rebuilds because it has a dependency on build-info.

Subject: [Starlingx-discuss] build-pkgs behavior: packages always compile

Hi Scott

I am working on the bug 1804687, and I have realized that some packages are rebuilt when "build-pkgs" is executed even if the package does not have new changes.

The packages mentioned are:

sm-common-debuginfo-1.0.0-20.tis.x86_64.rpm

sm-common-dev-1.0.0-20.tis.x86_64.rpm

sm-common-libs-1.0.0-20.tis.x86_64.rpm

sm-eru-1.0.0-20.tis.x86_64.rpm

sm-common-1.0.0-20.tis.src.rpm

sm-common-1.0.0-20.tis.x86_64.rpm

build-info-1.0-4.tis.src.rpm

build-info-1.0-4.tis.x86_64.rpm

build-info-dev-1.0-4.tis.x86_64.rpm

Is this behavior a bug? otherwise why are those packages built every time if they have the same version?

Note:

The fix for the bug is ready for review
