Why doesn’t Eclipse/Installation Manager work on Linux?

For the next time I’m grumbling about yet more incompatibilities causing problems with Eclipse on Linux, adding the following properties to the bottom of the launcher configuration file seems to help:

-Dorg.eclipse.swt.internal.gtk.useCairo=false
-Dorg.eclipse.swt.internal.gtk.cairoGraphics=false

For example, edit the install.ini file for Installation Manager, which is where I first encountered problems after updating Red Hat Enterprise Linux last year. The problem appears to be due to incompatible GTK and Cairo versions, and there’s a related IBM technote for Installation Manager on RHEL 6.6.

Unfortunately, while that was enough to get Installation Manager working, the Eclipse IDE still seems somewhat unstable. I been exporting the following environment variable for a while but, based on the SDK Known Issues wiki page, maybe that doesn’t make any difference with recent versions:

export GDK_NATIVE_WINDOWS=true

Another suggestion I’ve seen recently, related to tooltips, is to export another environment variable, although so far I haven’t tried it:

export GRE_HOME=/dev/null

Need to experiment a bit more with those last two, and see if I can narrow down whether there are any other real problems.
