Description Rob Sigel

Build Identifier: M20110909-1335

No compatible Browser libraries are found/loaded by SWT in a default install (fully updated/patched) of OpenSUSE 11.4. Eclipse-SDK-3.7.1-linux-gtk-x86_64 is forced to use the forms version of the Welcome View and external browsers for Help content.

As an Eclipse RCP developer, the lack of a compatible Browser component in the default install of a major distro is inconvenient.

The default install of OpenSUSE 11.4 contains XULRunner 2.0 (known incompatible - see Bug 327696) and the supposedly compatible WebKitGTK 1.3.10.

Package: libwebkitgtk-1_0-0
Version: 1.3.10-5.1
Provides:
libwebkitgtk-1.0.so.0()(64bit)
libwebkitgtk2 = 1.3.10
libWebKitGtk0 = 1.3.10
libwebkitgtk-1_0-0 = 1.3.10-5.1
libwebkitgtk-1_0-0(x86-64) = 1.3.10-5.1

A workaround is to install the latest version of the package mozilla-xulrunner192 from the repos. (No version of xulrunner192 is installed by default.) But according to the docs and SWT FAQ, SWT was going to be compatible with WebKitGTK 1.2.x+ as of Eclipse 3.7.0.

Reproducible: Always

Steps to Reproduce:
1. install a clean VM of OpenSUSE 11.4 x86_64
2. add the community online repos for updates
3. update OpenSUSE
4. download/install Eclipse 3.7.1
5. run Eclipse (add '-consoleLog -debug' to see log messages in the console about missing internal browsers)
6. observe the forms-based Welcome view (not HTML) at the initial startup
7. open Window->Preferences, select General->Web Browser
8. observe that "Use internal web browser" is disabled
9. observe the browser-related log message in the console, and in the Error Log view. (Yes, it mentions the lack of MOZILLA_FIVE_HOME, but that's only because there are no diagnostic logging messages when WebKit itself fails to load, despite it being the new default browser.)

Got the same bug. The problem is that old name of Webkit Gtk library was libwebkit, and a new name is libwebkitgtk.

Creation a symbolic link with old rules name solves the problem.

Try to create the link manually:

sudo ln -s /usr/lib/libwebkitgtk-1.0.so /usr/lib/libwebkit-1.0.so.2

Restart Eclipse, open Preferences Window and check "Use internal web browser" in General/Web Browser.

In my case internal browser works fine (at least on my Gentoo system).

The eclipse 3.7 and 3.7.1 releases should be able to use WebKitGTK 1.2.x and 1.4.x without problem.  Similar to GTK+, WebKitGTK uses odd minor revision numbers (ie.- the '3' in 1.3.x) to denote dev-stream work, which the Browser does not officially support, though I'm a bit surprised that it's not working "by accident".  Does OpenSuSE 11.4 really only ship a dev-stream webkit library, and not also something "proper" like WebKitGTK 1.2.x or 1.4.x?

re: comment 1
This should be working in eclipse >= 3.7.x.  Are you using an older version than this?

FWIW I just experienced the same problem.  I have Eclipse 3.7.1 on OpenSUSE 11.4 x64.  I had no "internal browser" option, and I was using a plugin (eclipse color theme picker) which created an SWT Browser instance.  I was blowing up with:

Caused by: org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
	at org.eclipse.swt.SWT.error(SWT.java:4308)
	at org.eclipse.swt.browser.Mozilla.initMozilla(Mozilla.java:1826)
	at org.eclipse.swt.browser.Mozilla.create(Mozilla.java:687)
	at org.eclipse.swt.browser.Browser.<init>(Browser.java:99)
	at com.github.eclipsecolortheme.preferences.ColorThemePreferencePage.createContents(ColorThemePreferencePage.java:101)

I have libwebkit installed (whatever 11.4 installed by default), and so I tried (perhaps naively) setting: -Dorg.eclipse.swt.browser.DefaultType=webkit

But that didn't work.

Then I found this issue, and per the report's workaround I installed xulrunner192 via YAST and it resolved the problem.

I can confirm this is happening in Arch x86_64 + Xfce too. I also solved the issue by creating a symbolic link:

ln -s /usr/lib/libwebkitgtk-1.0.so.0.13.4 /usr/lib/libwebkit-1.0.so.2

Thanks for this suggestion!

In the meantime we've implemented webkit2 support and SWT works on webkit1 and webkit2. Mozilla is deprecated.

528844 – (webkit2Default) [Webkit2] Make webkit2 default.
