Buld eclipse 4.32 under FreeBSD

[NorbertXYZ]

Hello,

I would like to build elipse for FreeBSD. I know there was a "port" done for release 4.24, but it is not updated any more. So I tried to take that port, but the differences between release 4.24 and release 4.32 made it difficult. So tried to start with a new adaptation of release 4.32 and took some advice from the existing port of 4.24.

I started with downloading:

git clone -b R4_32 --recursive https://github.com/eclipse-platform/eclipse.platform.releng.aggregator.git

Then I added some new "binary" files as basis for FreeBSD and patched eclipse files to include FreeBSD settings. Then I started the build with

export ARCH=$(uname -p)
export JAVA_HOME="/usr/local/openjdk17"
export MAVEN_OPTS="-Xmx2048m"
mvn -DskipTests=true -Dnative=gtk.freebsd.${ARCH} clean verify

By the wqay: Maven is version 3.9

The compilation started and was running for about 15 minutes. Then there were errors

maybe someone could give me a hint, what to do. I tried to get an "entry point" - but I don't see it. Yes, it is jface, but what is missing or wrong?

Attached my patches.

Many thanks from Muenster/Germany if someone could give me some help :-) Norbert

mmhhmmm... why? the previous steps all had enviroment freebsd/gtk/amd64 - but here it is freebsd/gtk/x86_64 - which does not fit. I don't know if this is the reason - but for me it seems...

Again - If someone could give me an advice - I would be very happy :-)

PS: Here the patches
eclipse.txt

[chirontt]

Do you have your forked repos somewhere that I can clone and try compiling them? They would be much better than a patch file.

In theory I can build all platforms/OSes (including this new-fangled FreeBSD) from any supported OS like Linux/Mac/Windows, even when I have no experience with FreeBSD nor any hardware running it, because the Java/Maven/Tycho build is fairly portable...

I've noticed one thing in your patch file:

             <environment>
+              <os>freebsd</os>
+              <ws>gtk</ws>
+              <arch>amd64</arch>
+            </environment>

Why define a brand-new arch=amd64? What benefits would it bring? Why not just use the existing arch=x86_64 available to all other OSes? i.e.

             <environment>
+              <os>freebsd</os>
+              <ws>gtk</ws>
+              <arch>x86_64</arch>
+            </environment>

I would also suggest that you try the arch=x86_64 for FreeBSD and make it work first, before trying other architectures such as powerpc64, powerpc64le, aarch64, etc., just to reduce the complexities involved.

[NorbertXYZ]

Thanks for the answer :-)

I do not have a repository till now - just started making progress my "own" way, sorry. Maybe I try to switch over...

I did what you recommended: I replaced the "amd64" architecture with "x86_64" and renamed files this way too - but the result is the same as with amd64... the build process stopped about 10 steps before the end. By the way why did I use amd64? Because of this:

uname -p
amd64

And by the way - FreeBSD (along with other *BSD OS'es) are as old (and even more) as Linux is. BSD is nothing new, but a less known, but very stable operating system, which has millions of users world wide. Okay, Linux has more users and has more popularity...

If I make some progress, I will let you know... Again thanks for your comments :-)

Cheers from Germany, Norbert

[chirontt]

I do not have a repository till now - just started making progress my "own" way, sorry. Maybe I try to switch over...

Note that I mentioned "repos" (plural); there are more than just one repo that need be ported to FreeBSD. If you examine the repo eclipse.platform.releng.aggregator closely, it actually contains many other repos as submodules, and at least 4 of those submodule repos need be ported to FreeBSD as they contain "binaries" which need be recompiled to be FreeBSD-specific native binaries.

uname -p
amd64

Why do you even need this uname command in the build? The building of any specific OS/arch combination is determined by their specific <environment> settings in various POM files and nothing to do with the uname command.

In your original post, you use this Maven command to start the build:

mvn -DskipTests=true -Dnative=gtk.freebsd.${ARCH} clean verify

That -Dnative=... option is not really needed, because it's used in various submodule repos to recompile their various "binaries" (which you already mentioned that you had already added them to your repos), not at the aggregator level. So the build command for the aggregator repo should be reduced to just:

mvn -DskipTests=true clean verify

Note that the above mvn command will build all OS/arch combinations specified in the POM file(s), not just your specific FreeBSD platform.

[chirontt]

Further more, if I was to do the port to FreeBSD, I would use the following approach (a divide-and-conquer strategy):

• Start with the submodule eclipse.platform.swt. Fork it and add the FreeBSD "binaries" (which need manual recompile for FreeBSD, using the Linux/x86_64 code as a base, I guess). Then build this forked repo with mvn -DskipTests=true clean verify to see if it succeeds.
• Do the same with the submodule equinox which itself depends on the submodule equinox.binaries, and maybe p2 (?)
• Do the same with the submodules eclipse.platform and eclipse.platform.ui
• Finally fork the aggregator repo eclipse.platform.releng.aggregator and port it to FreeBSD, with its submodules pointing to the above forked repos (where necessary). Building it with mvn -DskipTests=true clean verify should assemble all OS/arch combinations and produce various compressed files in eclipse.platform.releng.tychoeclipsebuilder/eclipse.platform.repository/target/products/ including the FreeBSD ones.

There may be other repos which contain Java source files to be changed also for FreeBSD, if they contain OS-specific code in their contents; for example, the eclipse.pde repo mentioned in your patch file.

[NorbertXYZ]

Thanks for the detailed description! :-) This will help much!
And for "uname -p" = "amd64" - I menion, because I do not know where the architecture was taken from - now I know from the environment in the pom files.

[laeubi]

Does freebsd really requires an own binary? According to this you can run linux binaries under freebsd: https://docs.freebsd.org/en/books/handbook/linuxemu/

beside this @chirontt already gave a very good and detailed overview, beside that you probably want to make sure we have a machine to build and run tests (is this possible e.g. on github runners?) then it would be much easier to help out with issues.

[NorbertXYZ]

Thanks! Yes, there is a Linux emulation layer - but it would also be nice to have a native port... :-)

[laeubi]

Thanks! Yes, there is a Linux emulation layer - but it would also be nice to have a native port... :-)

Then the main problem would be to get a native machine for that purpose (or some way to build/test on a linux machine)

[NorbertXYZ]

Again thanks for all the comments... First I must see what all means that you have written and second: If I make progress I will let you know :-)
Have a nice sunday, Norbert

[NorbertXYZ]

Hello back, again :-)

Today I made a big step forward and the build was successful... I took the advice to use x86_64 instead of amd64 (there was one thing, where I did not find a solution for amd64 nearby the end). The build log was finished with:

I could get the binary from:
eclipse.platform.releng.aggregator/eclipse.platform.releng.tychoeclipsebuilder/eclipse.platform.repository/target/products

and untarred the file:
org.eclipse.sdk.ide-freebsd.gtk.x86_64.tar.gz

although everything was without an error, but I could not find the executable eclipse/eclipse - what did I forget?

Thanks, Norbert

[HannesWell]

although everything was without an error, but I could not find the executable eclipse/eclipse - what did I forget?

Did you create an equinox-launcher project for your OS or at least updated the existing org.eclipse.equinox.launcher.gtk.linux.x86_64 with the binaries built for FreeBSD (if necessary?) as described in:
https://github.com/eclipse-equinox/equinox/blob/master/CONTRIBUTING.md#building-the-native-executable-and-launcher-library-binaries

But I don't know if that is even necessary or if the existing org.eclipse.equinox.launcher.gtk.linux.x86_64 works already as it is for Linux and x86_64?

[NorbertXYZ]

Thanks :-) I just took the description I found on github for eclipse-platform/eclipse.platform.releng.aggregator and another description for an older build (4.24) from FreeBSD. It was not mentioned that the "binaries" should be created additionally - I thought everything would be done in the eclipse build step...

I have to first understand what to do - then I will go further :-)

[NorbertXYZ]

@HannesWell: Your comment for the laucher took me some time today - but finally it seems, eclispe 4.32 works on FreeBSD :-) But to go further I will test more...

Thanks to all for the comments.. Without I would still be somewhere in between and some steps would be still open... :-)
