Fedora 2 & Eclipse

Fedora 2 & Eclipse

[Ricardo Gorosito]

Any news/progress about RH's Eclipse & Fedora 2? AFAIK oprifile is the 
'stopper'.

Thanks, Ricardo.-

The oprofile plugin is not really a stopper it is possible to build without as
it's an additional plugin.

I had Eclipse building with gcc-ssa and gcc34 mostly - ISTR the RHEL binaries
were working for someone out of the box.  The issues I hit are in the archives
- solib/gcjlib, various link problems, etc. 

I'll have another play this week sometime.

I got it building by basically s/solib/gcjlib/ in the eclipse patches.
You need a small patch to SWT to make it build with the newer Gtk.
Once this stuff is done, it seems to crash if you do anything real
with it; Anthony Green claimed better success but I'm not sure under
what conditions.

I was just running Eclipse 2 on RHEL with GCC 3.4's gij.

The only trick I had to do was to set the GCJ_PROPERTIES environment to
"gnu.gcj.runtime.VMClassLoader.library_control=never".  This prevents
gij from loading .so files that were built with previous versions of
gcj.  The binary compatibility ABI should fix this in the future.

Unfortunately, Eclipse would crash eventually.  I think everybody is
seeing the same crash.  mjw's mew line-number-in-interpreted-stack-trace
patch should help us debug this.

Hello,

I haven't received much traffic on this list, but I was wondering if it  
was still active?  I am trying to compile an SWT application to run on  
linux using gcj.  The application runs on SWT 3.0.1.  Here is the  
command line I am using:


gcj   -O2 -fjni  
--main=com.octetstring.jdbc.ldap.browser.JdbcLdapBrowserApp  
dist/osgi.jar dist/swt-pi-linux.jar dist/swt-mozilla.jar   
dist/swt-linux.jar   dist/runtime.jar  dist/boot.jar dist/jface.jar  
dist/ldap.jar  dist/runtime.jar  dist/ldap.jar dist/jdbcLdap.jar  
dist/jdbcLdapBrowser.jar -o ldapBrowser

After playing around with the ordering, I figured it was best to put  
osgi first,  but when I try this I get the error:

org/osgi/service/url/AbstractURLStreamHandlerService.java: In class  
`org.osgi.service.url.AbstractURLStreamHandlerService':
org/osgi/service/url/AbstractURLStreamHandlerService.java: In method  
`org.osgi.service.url.AbstractURLStreamHandlerService.equals(java.net.UR 
L,java.net.URL)':
org/osgi/service/url/AbstractURLStreamHandlerService.java:83: class  
'java.net.URLStreamHandler' has no method named 'equals' matching  
signature '(Ljava/net/URL;Ljava/net/URL;)Z'
org/osgi/service/url/AbstractURLStreamHandlerService.java:93: confused  
by earlier errors, bailing out

Is there something else I need to do?  I tried including rt.jar in the  
classpath, but gcj didn't like that very much.  I know you gotten  
eclipse 2.1 working with gcj, I was wondering if there had been any  
luck with 3.0 and the 3.0  libraries.  Any help would be greatly  
appreciated.

Yup - I've posted my patch to list before and you cast an eye on it and it
seemed sane.

Hmm, pretty sure got that far too.

IIRC I got splash and stuff working correctly then barfing on various runtime
linking issues.  This could be me, and I'm not overly familiar with how
gcj/eclipse deals with hybrid .so/java stuff.

It strikes me that it should be at least something that should go into Fedora
Extras for FC2 eventually.  I'll rebuild and log and try and poke people here -
I've had a lot of out of channel intrest from people via jpackage and other
forums for native eclipse so I would personally like to see it in fedora once
all the pain is gone.
