Re: [platform-dev] GTK4 Support in SWT / new GLIBC required for GTK3 in

Hi folks,

I am concerned that since this announcement we introduce a significant problem for our Linux user base. We had a preliminary discussion at the recent IDE call on Thursday and I am now going to try to document my case. For those interested I have raised https://github.com/eclipse-equinox/equinox/issues/830 and we should continue discussions there. To be clear, I plan on doing and maintaining the work required to resolve this issue, so I hope that the common "who is going to do it" + "who cares" questions are easily and quickly resolved.

Thanks

Jonah

Hi Everyone,

since today, SWT[1] ships GTK4 support for Linux x86, to enable this
with your SWT Application you need to specify

     SWT_GTK4=1

as an environment variable, please share any bugs or improvements and of
course any help for improving GTK4 is welcome.

There are currently some architectures outstanding to enable GTK4:

- aarch64
- ppc64le
- riscv64

reach out to the SWT team if you are interested in any of these and like
to see GTK4 for them as well!

As part of this effort it was required to update some build dependencies
resulting in a higher version of GLIBC (at least 2.36 for x86 other
architectures might require higher versions) this usually means you need
at least:

- Debian 12 or recent Ubuntu
- Centos 9
- ... or similar depending on your distribution

to run SWT (and in particular Eclipse) Applications, especially if you
are running UI tests and still using the deprecated centos-8 image [2]
you need to upgrade your builds to the new ubuntu based ones.

best
