Re: [platform-swt-dev] gtk port

I think he just wants to know how to self-host and run a workbench with 
his changes in it.
If that is the case, you don't need to build a new executable or new jars 
or anything. 
(Havoc, self-hosting is our term for developing Eclipse within Eclipse and 
running 
a second Eclipse workbench with your changes in it to try it out).

The steps we use on the VCM team are (SWT team members can correct if 
their setup differs):

1. Start Eclipse workbench.
2. Add the projects you want to hack on to the workspace using the 
repositories view
        and anonymous CVS.
3. Change code, implement new features, etc.
4. Select the project, Properties->Launcher. Select "Run-time Workbench". 
You only have
to do this step once.
5. Select the project and hit the running man icon in the Java 
perspective.

A new workbench will appear, and should be running with your changes. SWT 
folk can fill you
in on anything I got wrong above.

Hope this helps,

james

If you want to run a standalone SWT application you do not need the 
platform-launcher - this creates the eclipse executable which simply 
brings up a splash screen and launches Eclipse via a java command. 

If you just want to hack around SWT - you only need the swt library and 
the swt jar.  Look at the project org.eclipse.swt. 

For examples of simple standalone SWT applications, look at the project 
org.eclipse.swt.examples. 

In answer to the various questions you have raised: 

The splash_full.xpm and splash_basic.xpm are not part of the 
"platform-launcher" or anywhere else in CVS - they are added in by the 
guys who package up the build. 
You can get a copy of the files by downloading the linux motif eclipse SDK 
and look in eclipse/splash. 

The build.properties are read by an eclipse plugin which produces from 
them an ANT script and then ANT is used to build the jars and src.zip 
files for each plugin. 

All building of the libraries (swt-win32.dll, libswt-linux.so etc) is done 
by the SWT team and the compiled libraries are released into the CVS 
repository.  The code and makefiles for these libraries can be found in 
org.eclipse.swt/Eclipse SWT/motif/library etc. 

There are several articles about SWT on eclipse corner. See:

So I discovered anoncvs is available, which seems more promising than
the zip download, but am still getting nowhere on building the
thing. Surely there is a script that compiles/installs the IDE? I see
these build.properties files, what reads those? Should I be using
Eclipse itself to build Eclipse? Which of the modules listed in
CVSROOT/modules do I need to get started?

The web site has tons of docs on developing plugins and such, but I
can't find any docs at all that simply list which modules to grab from
CVS, and how to build/install the code after I have them.

I've found the "platform-launcher" module and run build.csh, but that
just generates a C executable that doesn't work - I run it as follows:

  $ ./eclipse -vm /opt/IBMJava2-13/bin/java
  Warning: Couldn't load the pixmap 
/mnt/space/cvs/eclipse-cvs/platform-launcher/library/motif/./splash/C/splash_full.xpm.

  Warning: Couldn't load the pixmap 
/mnt/space/cvs/eclipse-cvs/platform-launcher/library/motif/./splash/C/splash_full.xpm.

  Warning: Couldn't load the pixmap 
/mnt/space/cvs/eclipse-cvs/platform-launcher/library/motif/./splash/splash_full.xpm.

  Exception in thread "main" java.lang.NoClassDefFoundError: 
org/eclipse/core/launcher/Main

So my grep attempts aren't finding this class in the source code -
where does it live? find -name splash_full.xpm also turns up nothing -
where can I find that?

Sorry for the no doubt clueless questions, I'm sure it's all obvious
once someone points it out. ;-) Are there docs somewhere on this topic?
