On CentOS/RHEL 6 I successfully can run the Oxygen IDE (extracted from eclipse-jee-oxygen-R-linux-gtk-x86_64.tar.gz).

However I now wanted to upgrade to the latest version 4.14 /2019-12. After extracting eclipse-jee-2019-12-R-linux-gtk-x86_64.tar.gz I tried to run the eclipse executable, but I get on the command line the error "An error has occurred. See the log file".

The log file then shows:

What's going wrong? Is it possible to run version 4.14 /2019-12 on CentOS 6?

Please note: I need to do an offline install, therefore I used the .tar.gz archive. Also, I cannot upgrade the OS to a more recent version.

Older versions of Eclipse worked with GTK 2 and GTK 3. The newer versions only support GTK 3 so you'll minimally need to update to a newer GTK 3 version because apparently the GTK version you have does have libraries to satisfy what SWT needs. A great many GTK-specific problems have been fixed in the last years, so the option to continue using an older version of Eclipse is not ideal.

Thanks Ed.

I had a look at installing GTK3 on the CentOS 6 machine, but when searching for gtk3 via yum with the standard repos nothing comes up . - Are there other CentOS 6 repos providing gtk3?

Sorry, I have little expertise and experience with Linux. I only have a virtual box for that and try to keep it up-to-date with the latest. The last time I complained about an SWT problem that was specific to Linux (GTK), it turned out that I needed to update my OS version because it was deemed too old to be supported.

And I doubt there are many on this forum who can answer your question. Probably Google is your best friend in this case...
