[Help wanted] How to create a reproducible build (FairEmail)

81

Ok, even then, can I get an APK to check?

/PS: you can even host the APK on https://www.faircode.eu/ as it won’t be downloaded often.

82

I don’t want to publish a public version, so please contact me, for example by email, or else via the contact form, for a download link, stating which version you want to have built.

83

Please PM me here, the fdroid APK for Release 1.2114 Vallibonavenatrix · M66B/FairEmail · GitHub :slight_smile:

Diffliog is huge that .so :frowning:
fair2114.log.7z.001.zip (3 MB)
fair2114.log.7z.002.zip (1.8 MB)
(remove .ZIP from name)

@linsui @obfusk fyi (I’ll provide APKs in private if needed)

Is the same NDK being used as specified in build.gradle?

With a bit of luck, this will solve the difference in the Manifest file:

86

Let’s fix them one by one. Maybe with the bugsnag id fixed other diff will disappear. :slight_smile:

87

Yes

recipe: metadata/eu.faircode.email.yml · 162d1b429d468698e00bdb2cb2997744b9420ea4 · F-Droid / Data · GitLab
vs
upstream: FairEmail/app/build.gradle at 1.2114 · M66B/FairEmail · GitHub

88

And the ABI filters?

89

The build-id is different. We need to remove it.

90

Will this work?

91

we include all 4 arches, yes, or did you mean something else?

92

See Reproducible Builds | F-Droid - Free and Open Source Android App Repository.

93

There are more than 4 possible architectures, and that could lead to differences I guess.

94

you can see the APK here: Artifacts · fdroid build (#5371903075) · Jobs · F-Droid / Data · GitLab

95

Do you know how I can specify --build-id=none for the F-Droid version only?

96

I thought you can put

    externalNativeBuild {
        cmake {
            version "3.22.1"
            path "CMakeLists.txt"
        }
    }

in flavor with different cmake file path.

98

I guess this will work:

99

I checked the generated manifest, and the dummy static Bugsnag ID is part of it. I’ve also checked if the --build-id=none to the C compiler.

I have sent you a new build via PM. So, you can compare again, and hopefully the builds will be closer to each other.

You can download a new test version, with the build-id suppressed, via the same link:

The manifest difference is resolved in any case.

The diff file might be big, but it looks like mostly offset differences. The symbols seem to be the same (obviously a checked a few only).

I have no idea what’s causing this. The CMAKE and NDK version are the same in any case.
