Building on CentOS7 aarch

[deadline42]

I'm trying to build version 2.5.1 on CentOS 7 for Arm.
I ma not a wel versed in building Java projects with Gradle.

Here is my Gradle environment:

gradle -v

Welcome to Gradle 8.1!

Here are the highlights of this release:

• Stable configuration cache
• Experimental Kotlin DSL assignment syntax
• Building with Java 20

I assume you downloaded the source code archive of the release.

The versionFile task currently requires that it is run from within a git repository.
You can either initialize the directory extracted from the archive as a git repository and make a commit, so it can find a head commit hash or just clone the repository and checkout the version tag you want to build instead of using the source archive.

Thanks that did the trick, "gradle build" worked but when I try to run it using KafkaEsque script from the KafkaEsque-2.5.1.tar I get a message about a library, seems it is AMD 64 but should be AARCH64

sh KafkaEsque-2.5.1/bin/KafkaEsque

...
/root/.openjfx/cache/17/libprism_es2.so: cannot open shared object file: No such file or directory (Possible cause: can't load AMD 64 .so on a AARCH64 platform)

...

Not sure about this error, but it mentions a file in the openjfx cache directory. are you sure your openjfx is an aarch64 version?

[deadline42]

I'll investigate further, however, I did not install openjfx, so maybe it download the x86 version it into the cache directory
(as I mention I'm not Java programmer)

Do you do contract work? Can you contact me at [email protected]

Hi @deadline42,

I assume you're running on a machine that supports only aarch64/ARM64, and not x86/x64?

ARM builds are on my wishlist, but unfortunately the GitHub-hosted CI runners don't support ARM yet. Fortunately, the new M1/M2 MacBooks all have a compatibility layer that allows you to run x86/x64 as well with some overhead.

I guess you don't have such a compatibility layer on your system?

I'm not that familiar with Arch Linux but I think it doesn't use DEB or RPM files? I would be happy to provide packages for Arch Linux as well but I haven't used it before, and I'm not sure if our plugins support it. IIRC adding the DEB & RPM builds was pretty simple.

If someone would like to add Kafkesque to the AUR it would be great. I'm not sure what that entails but, e.g., for Homebrew for macOS we have a separate https://github.com/patschuh/homebrew-esque repo that's comparable to a custom PPA repo on Ubuntu.
