Re: [platform-dev] Eclipse Platform Build

[Vishnu Sarath]

Hi All,

I had to work on this issue and found that the changes in the commit : 
https://github.com/eclipse-platform/eclipse.platform.swt/commit/d8e3f297ffde54412d935db7dde31d276b58b635#diff-874667bd88035dc47251befdad240fb5cf39f7db50597060fe17c2ecb6082de5
 has caused this issue. But this commit seems to be added intentionally making 
the min version of GTK to 3.22. The crash occurs when we are right clicking 
(when trying to show a pop up menu) - getting gtk_menu_popup_at_pointer 
undefined symbol. Since this may not be present in gtk4. Earlier we used to 
have a separate handling if the gtk version was less than 3.22. I tried to add 
the removed native call and changes in Menu.java, Device.java and Shell.java 
and the right click functionality is working fine now.

I had to build the .so files used for gtk.linux locally for this. When I was 
doing that I created the .so using
`eclipse.platform.swt\bundles\org.eclipse.swt\bin\library\build.sh -gtk3 
install` command. The output .so files will be created using GTK3 binding (eg: 
libswt-pi3-gtk-4960r6.so ) and it will not have the .so corresponding to GTK4 
binding (expected as per the documentation).
* But will these .so files work for any platform (when the final product is 
installed) where the GTK version installed is GTK4. I am afraid that it will 
fail at some native calls for GTK4 (as I see we have GTK4 native calls made 
from  different UI java classes).
* When I checked the latest eclipse platform, it also contains only the 
"libswt-pi3-gtk-4960r6.so" (and no libswt-pi4-gtk-4960r6.so) in 
org.eclipse.swt.gtk.linux.x86_64.jar. So I just wanted to confirm during 
eclipse build also we are using -gtk3 and e haven't moved to gtk4 still. Please 
correct me if I am wrong at some point.


Thanks,
Vishnu

Thanks @mist...@redhat.com<mailto:mist...@redhat.com> for the detailed mail. I

are right clicking (when trying to show a pop up menu) - getting 
gtk_menu_popup_at_pointer undefined symbol. Since this may not be present in 
gtk4. Earlier we used to have a separate handling if the gtk version was less 
than 3.22. I tried to add the removed native call and changes in Menu.java. And 
created the .so files with building in Fedora38 VM (Glibc 2.37).
  *   But when I am using this .so files in the product and trying to launch 
the product in SUSE12 SP5, the launch itself is failing. When I tried find the 
root cause (adding some logs) I got the below error:

   It’s expecting Glibc version above 2.34 while the SUSE12 is 
having 2.22 by default.

I am a bit new to this, so could someone please guide me on how to fix this. Is 
this issue because I am using a wrong platform (with higher version of Glibc 
2.37 for building). What is the ideal platform which we are using to generate 
swt .so files for linux gtk.

Re: [platform-dev] Eclipse Platform Build

[Christoph Läubrich]

I'm not completely sure what type of "reminder" (to whom?) so if you 
have a support-contract with Eclipse/RedHat/... it might be good to use 
the dedicated support channels for that.


General questions about a specific issue are better handled on Github 
issues/discussions if you feel any documentation is unclear there as 
people often respond faster there and you reach a broader audience.


In general you can take a look at

https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/

what will build you a full eclipse ecosystem, this takes quite long, but 
is the best start for beginners, and you can take a look at the 
Jenkinsfiles of a specific project to learn how they are build 
individually, but building SWT (natives) is not a trivial task.


Beside that, eclipse offers old releases "forever" so you can use any of 
these if they work for your older product, but you will likely see 
issues combining "old" and "new" components in eclipse as a whole.


Its not clear if you have a specific patch, if yes you can submit it as 
a PR and then it will result (if merged) in the next integration-build 
repository to consume.

Hi,

In order to fix the SUSE crash issue : 
https://github.com/eclipse-platform/eclipse.platform/issues/212 
 (which 
is a critical one for us), we are trying to build the 
eclipse.platform.swt and eclipse.platform.swt.binaries locally and add 
to our product (built using maven tycho plugin), rather than getting it 
from the eclipse repo. So could you please help me with proper documents 
to do SWT and platform specific binaries locally?


Basically we are trying to achieve the below thing:

  * Upgrade all the plugins from eclipse platform repo to latest version.
  * But keep swt and org.eclipse.swt.gtk.linux.x86_64 plugins to the one
from eclipse platform 4.23 which is working perfectly in SUSE.

Thanks,

Vishnu

Re: [platform-dev] Eclipse Platform Build

Hi,

Does this help?

https://github.com/eclipse-platform/eclipse.platform.swt/wiki/Devel-GTK-Dev-guide

What I do to build the natives of SWT is:

cd .../bundles/org.eclipse.swt/bin/library
make clean
build.sh -gtk3 install

In your case you might want to instead checkout eclipse.platform.swt and
eclipse.platform.swt.binaries at the same tag (tags e.g. look like this:
v4960r6). Whichever SWT version you want to use, there should be a tag,
this tag can be used to checkout the binaries from the
eclipse.platform.swt.binaries repository.

I'm not sure how you would bundle whatever you built or checked out with
Eclipse though, without doing a full platform build (I only know this
option, maybe there are others):

https://wiki.eclipse.org/Platform-releng/Platform_Build

Keep in mind wikis could be outdated.

Best regards,
Simeon
