[eclipse-dev] Gtk+ launcher
|
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.
