'''Replace files'''
+
−
1) Download some build of eclipse:  [http://download.eclipse.org/eclipse/downloads/ Eclipse Download site]
+
−
2) Navigate to <code>/eclipse</code> folder that should contain your 'eclipse' executable. Rename the original executable to 'eclipseOLD' and copy your newly compiled one into it.

−
3) For the 'so' file, in the downloaded eclipse, navigate to the plugin folder, into the equinox launcher gtk folder. It should be something like:
+
−
  ~/Downloads/eclipse-SDK-N20150719-2000-linux-gtk-x86_64/eclipse/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.N20150719-2000
+
−
You can also find it via:
+
−
  find . | grep "eclipse_.*so"
+
−
Inside it, you should find an so like: <code> eclipse_1632.so </code>. Move the file, or rename it such that it doesn't contain an 'so' (e.g eclipse_old_1632). (eclipse will load the first found 'so' file, and it might confuse them if both are present). Now move your newly compiled <code>eclipse_1632.so</code> into that folder.
+
−
 
+
−
'''Verify'''
+
−
To make sure that eclipse launches with the files that you've actually replaced:
+
−
1) I personally put some print statement into the code, so when I run it, it is printed.
+
−
  eclipseGtkInit.c:
+
−
      int loadGtk() {
+
−
puts("Hello World\n");
+
−
2) Alternatively, launch eclipse and note the pid:
+
−
  ./eclipse & echo $!
+
−
Or use <code>jps</code> after it is launched.
+
−
3) Navigate to /proc/PID/
+
−
4) execute
+
−
  cat maps | grep eclipse_
+
−
This should list the eclipse_xyzz.so file that you copied to the plugin folder.

About

This page is info for developers interested in contributing to the actual Equinox source code.

Part of Equinox is launching Eclipse. It's like bootstrap code that get's the main jvm going.

Opening code in Eclipse

The repository contains a .cproject: 

 rt.equinox.framework$ find . | grep cproj
 ./bundles/org.eclipse.equinox.launcher/.cproject
 ./features/org.eclipse.equinox.executable.feature/.cproject  << Launcher in 'C'

You can import this project straight into Eclipse. (Import from Git, find projects, select the executable launcher).

There are many projects in Equinox. Most are java based except the executable launcher.

Gtk Specific Code
