Re: [eclipse-dev] Gtk+ launcher

["Mike Wilson" <Mike_Wilson@xxxxxxx>]

Oddly enough, it's the SWT team which is responsible for the launcher. I'll make sure this gets sent to the right person.

Thanks,
McQ.

A couple days ago I downloaded the Gtk+ version of Eclipse 2.0.  I was
surprised to find that there is still a Motif dependency in the
launcher.  We'd prefer not to have this, so I wrote a Gtk+ launcher.

It is appended, along with a simple Makefile.

To build it:

* cvs co platform-launcher
* mkdir platform-launcher/library/gtk
* cd platform-launcher/library/gtk
* make
* Copy the resulting eclipse-gtk to the Eclipse install tree

How do I go about getting this into CVS?

Apologies if this is the wrong mailing list.  I didn't see anything
more appropriate.

Tom
