Install Error - eclipse 3.5 - ubuntu 9.10

[Ryan]

I understand...I think you could still use Java 5 to build and run your applications, and use Java 6 just to run Eclipse.  You should be able to set that up within Eclipse, you would just have to change the JDK for each project.

Hi Ryan,

Sorry for the late response. Got caught up in a training.

As you suggested, I uninstalled Java 5 and installed Java 6 in my Linux machine. SlickEdit core is working fine now. Thanks for your help.

So now we can conclude that SlickEdit core has the dependency on Java 6.

However, as I had already informed, I want to use SlickEdit for Eclipse for Android Source which has the dependency on Java 5. Do you mean to say if I have to use Java 5 for build and Java 6 for Eclipse, should I disable "automatic build" in Eclipse IDE?

Do you have any plans to support Java 5 also? Please clarify.

Thanks and regards,

Hmm...yea I knew Core 3.5.0 depends on Java 1.6.0, we've had other threads about that, but I never thought that the error you were seeing had to do with the Java version  .  At any rate, at least we figured out the issue.

However, as I had already informed, I want to use SlickEdit for Eclipse for Android Source which has the dependency on Java 5. Do you mean to say if I have to use Java 5 for build and Java 6 for Eclipse, should I disable "automatic build" in Eclipse IDE?

I don't think you have to disable automatic build, just first make sure that you are starting Eclipse with Java 6 (so that Core runs).  Now in your Eclipse workspace, right-click on your Android project and select Properties.  Select the Java Compiler node, and as shown in the attached picture, set the compliance level for 1.5.  Click OK and apply the settings.  I think this should do it.

Do you have any plans to support Java 5 also? Please clarify.

Yes, for our next release we plan on running with Java 5 or later.

Let me know if the above instructions work for you.

Hi Ryan,

It works now. I am able to build the source using Eclipse with the compliance level for 1.5.

I have a basic doubt with Java settings (I am not sure if I can ask you). Lets say I have Java 1.5 also installed in my Ubuntu. How do I set to use Java 1.5 or Java 1.6? Should I keep changing the environment variables and Java alternatives every time I want to switch between the versions? It will be great and highly helpful If you know and share the same.

Thanks and regards,
Hariprasad

I am guessing you want to keep Java 1.5 in your PATH, but start Eclipse using Java 1.6, and not have to keep changing your PATH environment variable all the time?  This you can do by specifying the vm argument to Eclipse.  To tell Eclipse what Java to use, you can do the following on the command line:

./eclipse -vm /PATH/TO/JAVA/6/bin/java

You can put this in the eclipse.ini file (located in the Eclipse root directory) so that you don't have to specify it on the command line every time (or write a script).  Just make sure that the -vm argument comes before the -vmargs arguments in the .ini file, because those arguments are passed directly to the vm.  Here is an example of what my .ini file looked like after I changed it:

-startup
plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.0.200.v20090520
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
/usr/java/jdk1.6.0_16/bin/java
-vmargs
-Xms40m
-Xmx256m
-Xss1024k

Once you have this specified you can just start Eclipse, and it will start using the specified Java each time.

Does this help?  Now, if you want to change what version of Java you are using to run Eclipse a lot, I suggest just making a couple scripts, each of which will start Eclipse with the desired -vm argument.  This way you don't have to keep specifying the argument on the command line, or keep editing the .ini file.

Greetings,

You need to make sure you are using a 32-bit Java from Sun (not gcj that is included on the system), as well as 32-bit Eclipse.  You also need to make sure you are using Java 1.6.0 or later for Core 3.5.0.

Are you positive that all of these requirements are met?  If this is the case, and Eclipse with SlickEdit still won't work, can you run Eclipse as follows, from the command line:

Code: [Select]

./eclipse -vstrace

When Eclipse starts, do something SlickEdit related, like go to Help > About SlickEdit Core and after you get an error, go back to the command line and copy the output.  Now paste it here so I can take a look.

One other thing you might want to try as a test, is to start Eclipse with a brand new workspace, and see if that makes any difference.

Did Eclipse run fine before you installed SlickEdit Core?  Or had you not tried that?  If not, you should definitely try that because there is no output from SlickEdit before that seg fault.  Install a clean Eclipse and try doing the same things you are doing now.

I'd be curious to know if that works or not, because there are a lot of postings in various places about libpango crashes on Ubuntu with Eclipse.  I'll keep looking and see if I can find anything that looks promising.
