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.
Gtk Specific Code
about
The gtk specific code of Equinox handles the splash screen and workspace file chooser.
location
./features/org.eclipse.equinox.executable.feature/library/gtk
building Eclipse executable
inside the gtk folder, run:
sh build.sh
To start a build. It will produce an executable 'eclipse'.
When you first launch make, it may complain about missing java:
../eclipseJNI.h:15:17: fatal error: jni.h: No such file or directory
In this case, you need to specify your java path. Usually this can be done via:
export JAVA_HOME=/usr/lib/jvm/java/ sh build.sh #then run your bulid.
Once build, you should see the following file in the gtk directory:
eclipse eclipse_xyzz.so #where xyzz is something like 1613
running compiled units
To test what you've build, you need to find a regular eclipse and replace it's files with those that you compiled.
Replace files:
1) Download some build of eclipse: Eclipse Download site
2) Navigate to /eclipse
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: eclipse_1632.so
. 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 eclipse_1632.so
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 jps
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.
