Native support for Eclipse SDKs on riscv64

[yuzibo]

I am trying to build Eclipse SDKs on riscv64. It's obvious that this is the correct repo so I opened the issue to keep track of various tasks done and/or underway like WoA did.

• add support for riscv64 to eclipse.platform.swt submodule
  • Add support for riscv64 eclipse.platform.swt#1444 for build.sh
  • Add linux riscv64 build with bundles eclipse.platform.swt#1445 add linux riscv64 build

  • Build gtk.linux.riscv64 native SWT fragment eclipse.platform.swt#1474 Build gtk.linux.riscv64 native SWT fragment
  • Bump riscv64 version eclipse.platform.swt#1490 bump riscv64 version [closed, combined into 1474]
  • Add support riscv64 with p2.inf eclipse.platform.swt#1485 Add support riscv64 with p2.inf
  • Once JustJ supports riscv64, to reset Jenkins to use it as native jdk
• Add support for riscv64 on equinox submodule
  • Add support for Linux on riscv64 eclipse-equinox/equinox#669
  • Version bumps for 4.34 stream eclipse-equinox/equinox#672 Version bumps for 4.34 stream [closed; combined into the PR ]
  • Enforce pick-up of linux.riscv64 root-files in equinox.executable.feature eclipse-equinox/equinox#680
  • ToDo: once gtk.linux.riscv64 environment is enabled in general, revert the temporary addition of the linux.riscv64 environment in o.e.equinox.executable.feature/pom.xml:
    • Revert temporary local addition of linux.riscv64 in executable.feature eclipse-equinox/equinox#681
  • Once JustJ supports riscv64, to reset Jenkinsfile to use it as native jdk.
• add support for riscv64 on eclipse.platform.ui submodule
  • Add riscv64 fragments to org.eclipse.e4.rcp feature eclipse.platform.ui#2318
• eclipse.platform.releng.aggregator
  • [Draft] Bump jna version to 5.15.0 #2348
  • Add linux.riscv64 environment to eclipse-platform-parent and publish linux.riscv64 artifacts #2394 Add linux.riscv64 environment to eclipse-platform-parent and publish win32.aarch64 artifacts
  • Add linxu/gtk/riscv64 the SDK4Mvn.aggr #2397 Add linxu/gtk/riscv64 the SDK4Mvn.aggr
• add support for riscv64 on eclipse.platform submodule
  • Add constant for riscv64 architecture in Platform class eclipse.platform#1575
• Add support for riscv64 on JustJ
  • https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/5031 Add riscv64 ci node for JustJ
  • Update for Java 23 and add scaffolding for riscv64
  • Fully enable riscv64 support
• Add riscv64 support for eclipse infra
  • https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/4978 Add riscv64 ci node for eclipse
• external porting work
  • linux-riscv64 was not synced in MANIFEST.MF on jna-5.14.0.jar  java-native-access/jna#1622
• Package support for riscv64
  • Packages for riscv64 eclipse-packaging/packages#213

Next I will always update this.

On Debian Sid riscv64, Milk-V Pioneer.

That is amazing!

Since the latest I-build the Eclipse SDK is also build for linux.riscv64

• https://download.eclipse.org/eclipse/downloads/drops4/I20240929-0810/

Implementation-wise almost everything is done now, the last pending two PRs should succeed now too.

The only thing that are missing to complete this entirely are some form of tests, at least smoke tests, ideally full I-build tests (for Windows on ARM they are still pending since some preparatory work to simplify their setup is not yet completed).

Furthermore we could/should provide the Eclipse-Packages for linux.riscv64 too, similar to WoA:

• Packages for Windows on ARM eclipse-packaging/packages#162

But unlike WoA since shouldn't be too difficult since Temurin already provides JDKs for linux.riscv64 and JustJ is now able to provide JDK bundles since there is also a Eclipse-SDK for it.

Test with the newest official Integration Build, on Debian Sid riscv64, Milk-V Pioneer, with x11 forward:

https://download.eclipse.org/eclipse/downloads/drops4/I20240929-0810/

Choose Eclipse SDK -> Linux (64 bit version for RISC-V) to download.

I would like to express my heartfelt gratitude to everyone for your efforts in achieving Eclipse support for riscv64 here. Your hard work and help are truly appreciated!

Okay, no problem, I will add these into the todo list also.

Yeah, I noticed this also. I will ping JustJ first.

Thanks for all again!

Thank you for these nice words, it's great to get them.
And thanks for all your contributions.
I think adding support for more arches challenges the complexity of the overall Eclipse SDK project and helps to reduce it.

@merks is already aware of the need for a change in JustJ and has already prepared it:

• eclipse-justj/justj@07754f5
• eclipse-justj/justj@6571be4

and is currently working on providing the new artifacts.

@yuzibo

There is an installer with an embedded JustJ JRE available for rsicv64:

https://download.eclipse.org/oomph/products/latest/eclipse-inst-jre-linux-riscv64.tar.gz

The installer filters products that don't support that architecture (and I've been fine-tuning that support today), so it only shows applicable products, i.e., only the Eclipse SDK can currently be installed:

It would be much appreciated if you could test whether the riscv64 installer works given I have no way of testing it myself.

\o/.

Okay, No problem, I will test it on my local riscv64 hardware ASAP(maybe in next days because I am on my holiday).

Thanks for your work again!

if i didn't do anything wrong, I think the eclipse installer is working:

Thanks for your work again!

So the left work for riscv64 on Eclipse is to use justj to replace temurin I think.

But I am not sure how long this will happened to update the link of downloading of justj

As mentioned in eclipse-packaging/packages#213 (comment) mostly everything is in place to produce riscv64 packages for M2.

It will appears here:
