Hi everyone,

<< Originally I posted this in 'Newcomers' but was advised to repost here >>

I've spent a few days now trying to figure out how to build 64 bit SWT for use in an Eclipse Java project I'm working on. There are various resources in the FAQs that seem to be almost what I need, but not quite up to date:

I extracted the sources from CVS as per these instructions...
http://www.eclipse.org/swt/cvs.php

I found build instructions here
http://www.eclipse.org/swt/faq.php#gtk64

and here
http:// www.nbinteractive.com/Free_Resources/internet_tech_blog?arti cle_id=302

But they are both not quite up to date, so I'm trying to guess my way through the recent build scripts without - I think -much success. Here's what I'm doing...

1. Rename .classpath_gtk in org.eclipse.swt to .classpath
2. In org.eclipse.swt.gtk.linux.x86_64, run build.html as Ant Build with target 'build.jars', which gives this output -

Buildfile: /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/build.x ml
properties:

[jar] Building jar: /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/swt.jar
BUILD SUCCESSFUL
Total time: 6 seconds

So no replace.32.to.64 build target exists, but this seems to have built the 64 bit version of SWT as intended.

3. Refresh org.eclipse.swt
4. FAQs say run the Ant build script again, with 'buildNatives' as the target. Again, this doesn't exist, so I've gone for 'buildSources'.

Buildfile: /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/build.x ml
properties:
init:
build.sources:
properties:
init:
src.zip:
copy.gtk.src:

[copy] Copying 684 files to /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/temp.fo lder/@dot.src
copy.translationfiles:
is64:
[echo] Is64=true
replace64:
[echo] Converting java files to 64 bit
[zip] Building zip: /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/src.zip
[delete] Deleting directory /home/mja/workspace/org.eclipse.swt.gtk.linux.x86_64/temp.fo lder/@dot.src
BUILD SUCCESSFUL
Total time: 2 seconds

All still looking good.

5. Refresh the gtk_linux_x86_64 project to pick up new sources.
6. And we are allegedly complete. However, when I attempt to build and run my 'HelloJava' application, I still have the error

Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM
at org.eclipse.swt.internal.Library.loadLibrary(Library.java:19 7)

at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java: 54)
at org.eclipse.swt.widgets.Display.<clinit>(Display.java:132)
at HelloWorld.main(HelloWorld.java:12)


I'm clearly missing something, but I can't see what. I'm an experienced Linux dev, but on RT Linux for embedded platforms. I don't normally get involved in Gui work (on Linux).

My Eclipse is
Version: 3.5.2
Build id: M20100211-1343

The x86_64 is 3.647

I'm running Ubuntu Lucid Lynx.

I can't quite see what's going wrong here; either I'm not building the correct targets, or I'm building them but my linkage in the 'HelloJava' for 64 bit SWT is not quite correct,

Any help would be greatly appreciated everyone Smile

Sorry i dont have solution but i have a query...

Why not download an eclipse for 64 bit linux and start developement directly???

I mean it will contain all the required librarys(SWT and all others required for RCP App).

http://www.eclipse.org/downloads/download.php?file=/technolo gy/epp/downloads/release/galileo/SR2/eclipse-rcp-galileo-SR2 -linux-gtk-x86_64.tar.gz


---------------------
why, mr. Anderson, why, why do you persist?
Because I Choose To.
Regards,
Vijay

Okay, so I found the 64 bit archived file for Swt here after some more poking around.

http:// download.eclipse.org/eclipse/downloads/drops/R-3.5.1-2009091 70800/index.php#SWT

Which I was able to download and Import into my Java application, which now links against the correct 64 bit version.

The solution was indeed straightforward, but answers are only easy when you have them.

Thanks to Vijay for the response, which at least pointed me at the archive server as a possible solution.

In case it's not obvious, I've posted his response with the link I used in case anyone else has the same problem.

Well, if you look at your step 4, it's not doing anything at all but building a source archive. So that's not right at all. I think if you take your swt.jar and shove the native libraries (which you don't need to rebuild, just take from the x64 branch) into the jar, you should be fine. That's generally what I do when I need to rebuild. I'm sure there's a more elegant solution, but that would work.
