RSSOwl

[Anthony Green]

Here's an RSSOwl 1.2 SRPM (and itext dependency SRPM) suitable for
submission to FE:

http://people.redhat.com/green/FE/devel/

This is based on the work that Robin Green and Andrew Overholt did.

I modified itext to not encode images in JPEG (since we don't support
that yet), and rssowl was modified to use standard JCE classes instead
of the bundled BlowfishJ.jar.  I also had to tweak the SWT code a little
to work with the version we ship.

It seems to work well for me (with my pr13212.so hack).  It would be
nice if others could try it before I go through the submission process.

Thanks,

AG

I get the following trying to build itext on FC4:

BUILD FAILED
/export/home/orion/redhat/itext-1.3/itext/src/build.xml:88: The
following error occurred while executing this line:
/export/home/orion/redhat/itext-1.3/itext/src/ant/site.xml:41:
java.lang.ClassNotFoundException:
org.apache.tools.ant.taskdefs.optional.TraXLiaison

perhaps a missing BuildRequires?  Have you tried building in mock?

ant-trax I think.

No, I've never used mock before and only recently heard of it.  Any
pointers?

I have no idea what this is.  I tried building on FC4 and didn't have
this problem -- but I did hit another problem that is unlikely to be
fixed in FC4 (missing methods in libgcj's AWT implementation).

I think RSSOwl will have to be for FC5 and greater only.

Thanks for the mock pointer.

I haven't tried to build the package myself yet (libgcj 4.0.x is missing
Font.getStringBounds() among other things), but try this:

Add near the top:

BuildRequires: ant-trax
BuildRequires: jaxp_transform_impl

Add right before the call to ant/setting of CLASSPATH:

export OPT_JAR_LIST="ant/ant-trax jaxp_transform_impl"

It is good practice to *always* set OPT_JAR_LIST and CLASSPATH. In fact,
the %ant macro could force these to empty if they don't exist;
otherwise, these things crop up with ant's auto-loading, which we don't
want during a build.

Thanks.  I made these changes and submitted both itext and RSSOwl to
Fedora Extras for review.

JPackage has a somewhat old version of blowfish-j that could have been
brought over. I guess avoiding extra dependencies could be a good thing.

itext doesn't build on gcj 4.0.2. I am going to update to the latest
4.1.0 in devel and see how it goes.

I am trying to build eclipse with gcc version 4.1.0 20051222 (Red Hat
4.1.0-0.11) since a new libgcj is required for itext and rssowl.

I don't know what's causing your error, but 4.1.0-0.12 is the latest and
has a bug fix that was crucial (... perhaps just for i386, though ...).  I
didn't have this problem when I built, though.  Want me to verify that it
still builds?  I did a build yesterday on my i386 laptop and it made it all
the way through.

This is odd.  Here's the line from jni.h:

extern JNIEXPORT jint JNICALL JNI_OnLoad (JavaVM *, void *);

I would assume that the problem is that we're somehow picking up the
wrong jni_md.h -- I would say that we're missing jni_md.h but I would
expect another error message if that were the case.

Could you run that compilation command by hand, but instead of '-c',
use '-E'?  Then save the output, compress it (it will probably be
huge), and email it to me.  That might help.

This was it, I think. You of course were able to figure it out faster
than I did, but I didn't get your email until later.

For whatever reason, jni_md.h in java-gcj-compat was not symlinked to
the real jni_md.h. I checked the java-gcj-compat spec and it does appear
 to be setting the links up correctly, and after reinstalling the
java-gcj-compat rpm, it seems fine.

Inside jni.h there's an #include <jni_md.h>, and these are in the
internal compiler directories. So, if the -I/usr/lib/jvm/java-1.4.2-gcj
specified on the command line takes precedence over the internal
compiler directories, then the jni_md.h -> jni.h header would have been
included instead of the real jni_md.h in the internal compiler directory
(without warning I guess...).

Now, my larger issue seems to be I am running out of memory during the
aot-compile-rpm stage of the eclipse build (I have 1G RAM). The problem
is that the machine doesn't necessarily lock up but it crawls for a few
hours (very unresponsive to mouse movements or key presses). Is it
really normal for the system to become so unresponsive like this? A
rogue process like this should eventually be killed by the kernel at least.

Eventually, I am getting an internal compiler error, so it might not be
available memory after all. I will try with the latest gcc rpm now.
