Compiling Eclipse on Pi (Pi4?)

[clicky]

Hi all,

I would like to start this discussion about Eclipse and Pi.
Now we have Pi4 and it getting close to a 'desktop computer' it would only be fitting to have appropriate (alternative) of Java IDE. I am aware that 'eclipse' (and 'eclipse-jdt') is available through standard Raspbian repos, but it is 3.8 (the latest is 4.12) and not upgradeable (there are some issues with repo setup).

I've tried to trawl the internet for anything else but failed. Only thing I found is source from where that 3.8 (I think) version came from: https://github.com/turesheim/eclipse-rpi.git

Following that I found this: https://git.eclipse.org/c/ and from there https://git.eclipse.org/c/platform/ecli ... gator.git/

I've played a bit with Torkild's script and tried to build newer versions - starting from R4_4 (which cannot be built due to being too old and pointing to non-existent repos) R4_12 (which doesn't have arm support any more) and ending up with R4_11 and failed.

I've tried to build it just through maven directly and I tried to build 'arm' (native) version and each time it would fail in different way. I tried to remedy some of the errors but not really managed to get anywhere.

Last thing I did was this: https://www.eclipse.org/forums/index.php/t/1099602/ (fingers crossed)

So, any ideas, pointers, previous experience or anything you can add regarding this subject - please post here

My pointer is that I have given up trying to do this. The Eclipse build is a total mess. Debian are/were thinking of dropping it entirely from their repos because it's almost impossible to build.

If you do succeed - note down how you did it!

I get it - there's quite a lot of 'hidden knowledge' buried there - somewhere.

BTW I am trying - this is the latest: https://github.com/turesheim/eclipse-rpi/issues/4

If you do succeed - note down how you did it!

Huh - of course. It is really hard to track going blind through options - especially when you're determined to do it. So many dead-ends and backtracking, etc. But, if nothing else if I (or someone else!) succeed in it - at least we'll know it is possible and I am happy to give it a go again (or assist anyone wanting to do so).

Also, it would be nice, then, propagating it further to the distro or something...

[clicky]

OK. I moved from square one - I managed to create .so files in org.eclipse.swt.gtk.linux.arm of R4_11_maintenance branch.

Now, it is really proper bodge I end up with - manually finding build file, moving folders around, installing randomly 'stuff', etc...
But result is in:

Code: Select all

libswt-atk-gtk-4924r25.so
libswt-cairo-gtk-4924r25.so
libswt-glx-gtk-4924r25.so
libswt-gtk-4924r25.so
libswt-pi3-gtk-4924r25.so
libswt-webkit-gtk-4924r25.so

I really wish I have someone beside me who understands 'things' to help:
- why that build script is not invoked by ant
- what we really need for first error ("Please install webkitgtk4-devel.ARCH on your system") or is it just a red herring
- if I have .so files what then! (only thing I can think of is get some zip file distribution of eclipse for linux and replace existing .so files in there with those I created and hope for the best)
- do I need to build some other c files somewhere else (I'm sure that there are other places where c files exist)

Also, I'm aware that some of those questions really need to be posted at Eclipse people - but so far I've not no response over there...

This is interesting:
- compiling R4_11_maintenance branch on Mac and RPi - fails!
- compiling R4_12_maintenance branch on Mac succeeds but fails on RPi

Difference between Mac and RPi are:
RPi: Java 1.8.0_211, mvn 3.6.0
Mac: Java 1.8.0_111, mvn 3.6.1

(I don't think that's what causes it to fail)

Now - I'll just try to compile .so files (and main 'eclipse' executable) on the same version on RPi and replace them in x86_64 build to try it out...

Some progress:

I actually have been running Eclipse on my 3B+. Some features run a little slow but for the most part it works just great. The problem I had was switching to Raspbian v3.1.1(new Buster). The new Java causes the load version of Eclipse to crash at startup. Not happy with the twiddling Oracle has been doing to Java. Going to wait for the apt update for Eclipse to catch up I guess.

Which version of Eclipse? If it is one supplied by Raspbian repos (3.8) it is way too old. It works (I think ) if you switch from OpenJDK 11 back to Oracle's JDK 1.8. And even then, I found out that I cannot access marketplace (was it called marketplace or was it delivered in that version of Eclipse at all?) nor update/upgrade/install anything...

[clicky]

OK. Last night (I stayed late as it was so interesting) I had a breakthrough. I'm through the breeze blocks wall now - just to find steel reinforced concrete behind it!

Anyway - issues I had was because Java was passing 32bit (int!) method signatures to JNI layer and it couldn't find methods as they all had 'longs' (passing "(II)I" for signature while particular method was in reality "(JJ)J"). All in SWT.
I've fixed it in Java (6000+ lines class called Display plus a few minor bits) just for it to crash while JDK because of pointers (32bit pointers) passed around in (GDK class) in such ways it break things (my current theory). Maybe I am not thinking regarding it in the right way. Maybe I should look at 'fixing' it from perspective of JNI (c) code and keep Java code intact. That might be next attempt.

Launcher working (see previous posts with screen shot) gave me some moral boost... we'll see... It would be really great finding anyone involved in Eclipse project to at least say 'hi' in this or their forums or anyone else who is good with such kind of code tinkering...

... or yet better - port their Open J9 for ARM!

Spent a few hours trying to figure out how to install Eclipse. I think this is something worthwhile for the community now that the Pi can be used as a desktop replacement.

[clicky]

I've put it aside for a moment - got to see that Eclipse foundation decided not to support 32bit Eclipse any more and half of the code reflect it and another not. I tried to understand how C code and how Java code detects if it is 64bit platform or 32bit platform and failed. I tried to bodge code to extend and even that didn't work.

It seems it requires someone who understand things slightly more and is willing to put more time in it. I am more than happy to help or to try things someone else suggests - but right now I don't have many options open except long steep curve to learn more and just blindly trying again and again...
