Description Daniel Wille

I just upgraded my workstation to CentOS 7.4, and I've observed Eclipse Oxygen linking against an older SWT library. The following are the WebKitGTK libraries provided on CentOS 7.4, from newest first to oldest last:

/usr/lib64/libwebkit2gtk-4.0.so.37 -> libwebkit2gtk-4.0.so.37.14.14
/usr/lib64/libwebkit2gtk-4.0.so.37.14.14

/usr/lib64/libwebkitgtk-3.0.so.0 -> libwebkitgtk-3.0.so.0.22.17
/usr/lib64/libwebkitgtk-3.0.so.0.22.17

/usr/lib64/libwebkitgtk-1.0.so.0 -> libwebkitgtk-1.0.so.0.22.15
/usr/lib64/libwebkitgtk-1.0.so.0.22.15

The "-1.0" is a super-old version of WebKitGTK, followed by the "-3.0" which is WebKitGTK 2.4. The newest available version is the "-4.0" library, which is WebKitGTK 2.14.

Eclipse is linking against the "-3.0" if it's installed. If I uninstall the "-3.0", Eclipse will link against the "-4.0". Could the behavior be changed so that the "-4.0" is preferred to the "-3.0"?

Very interesting that you noticed this.

-4 is basically webkit2 with gtk3 bindings, -3 is webkit1 with gtk3 bindings.

Currently the webkit2 port is in progress:
Bug 516838 – [GTK3][webkit] Port SWT Browser to webkit2gtk (4.8) 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=516838

There are a few more tasks left to work on, and then it will be set to be used as default.

In the meantime, you can force eclipse to use webkit2 via:
export SWT_WEBKIT2=1
eclipse

Let me know if you have any questions.
