Try using "-findirect-dispatch" as custom GCJ flag in the GUI.

Don't work with the command line version unless you know exactly what 
you're doing. You'll be well off using the GUI.

[jnc-users] Undefined reference :: Log4j

[chosen f. <cho...@ya...>]

Hi, 

I'm trying to create a simple program that uses log4j. Unfortunately, I can't seem to make it work. I've used 2 methods in creating the EXE: 

A. Using the JNC UI:
   1.  In Step 1, I indicated my the .java file of my program (in Files), the directory of my program (in Directories), and the log4j jar located in my program's directory (in Archives).
   2. In Step 2, I set the main class by selecting my (only) java file. I only checked the Windows checkbox, and left everything else blank. 
   3. In Step 3, the only thing I enabled is the Show used commands checkbox.
   4. When I try to compile my project (Step 4) I get an error : 

      org/apache/log4j/jmx/Agent.java: In class 'org.apache.log4j.jmx.Agent':
    org/apache/log4j/jmx/Agent.java: In method 'org.apache.log4j.jmx.Agent.start()':
    org/apache/log4j/jmx/Agent.java:0: error: cannot find file for class com.sun.jdmk.comm.HtmlAdaptorServer
    org/apache/log4j/jmx/Agent.java:0: confused by earlier errors, bailing out


      while  it's  "processing log4j-1.2.13.jar". It seems that no .o file for my program was generated since it hasn't processed my program yet.

B. Using the command line
   1. I tried compiling my .java file using the command:
       gcj -c -g --classpath=C:\logtest\log4j-1.2.13.jar LogTest.java -o LogTest.o
      and it generated a LogTest.o file.
   2. Then I tried to build the EXE using the command: 
       gcj --main=test.gcj.LogTest -fjni -Llibs/win -Ilibs/win/gui/gui.jar -o C:\logtest\LogTest.exe -s -O2 -ljncNoGui -ljncNoJce -ljncTrial -IC:\logtest LogTest.
      and it shows an error : 
   LogTest.o: In function `ZN4test3gcj7LogTest18__U3c_clinit(unsigned e_E, __complex void, void)':C:/logtest/test/gcj/LogTest.java:8: undefined reference to `org::a
ache::log4j::Logger* org::apache::log4j::Logger::getLogger(java::lang::String*)'
:C:/logtest/test/gcj/LogTest.java:8: undefined reference to `org::apache::log4j::Logger::class$'
collect2: ld returned 1 exit status

Now I'm stuck... Help would be much appreciated...

So it's HelloWorld.java or HelloWorld.class, right?

Why "Hello.so"? .so is a shared lib, you're creating a binary. But this 
has nothing to do with your problem.

What now? HeloWorld.java? This has to be HelloWorld.

You can exclude AWT/Swing, you don't need it for that simple 
application. But again, this has nothing to do with your problem.

Here again, you're compiling HelloWorld but specify HeloWorld as main class.


Hope that helps...

[jnc-users] java.text request

[Lee D. P. <le...@3s...>]

Marco,

I have been looking to compile our application with JNC and we are now a
step closer to moving this into production. The one concern I have, is
that the java.text package in the latest release is from the Sun JRE.
Our application is SWT and I'd like to exclude GUI stuff altogether, for
size and licensing reasons. =20

The 1.0 version of JNC used java.text from the GNU classpath, I have
absolutely not issues with this version of JNC and will continue to use
it for the foreseeable future. My executable is an acceptable 2.3MB and
I have no licensing issues.

The 1.1 version includes java.text from the Sun JRE and so there are
both licensing and size issues with this.=20

Changing our source code is not really an option; we use many of the
date format functions of java.text as well as internationalization using
ResourceBundles etc.=20

So my question, would you consider reverting back to GNU classpath for
java.text in a future release (we have not encountered any problems with
it so far). Or at least provide the option to use java.text from the GNU
classpath so that we can continue to upgrade and use the latest version
of JNC.

Regards

Lee

Well, here we have the strange thing you're doing. Using my GUI with an 
foreign GCJ... If you mix software together, you should know what you're 
doing (or at least tell when you send bugreports ;-)).
Why don't you use my version?

Re: [jnc-users] Binaries still need Runtimes?

[Norman <no...@sm...>]

Hi,

so here is the info you asked for:

Operating System:
I compile on an openSuSE 10.2 (i586) an get the error on a SuSE Linux 9.2
(i586).

JNC version:
1.1.1 - looked on the downloadsite today so i guess it is latest.

GCJ:
gcj (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)
Copyright (C) 2006 Free Software Foundation, Inc.

Package from the SuSE Repository.

What did you do:
of course NOTHING :-)
No serious. I added the sourcefiles and compiled them with standard
settings given in the GUI. It works on the machine i compiled on. Then i
tested the program on the other system, which is a console-only, very
small system.
The rest you know.

Can you reproduce the problem with a simple "Hello World" application?
In fact i can!

-----------------------------------
package hellotest;


public class test {


    public test() {
    }


    public static void main(String[] args)
{
        System.out.println("Hello World!");
    }

}
-------------------------------------------------

Works on the compiling machine
Still on the other machine:
./hello
./hello: error while loading shared libraries: libgcj.so.7: cannot open
shared object file: No such file or directory

Can you give me some more info?
- What operating system do you use?
- Which JNC version?
- Did you use a custom GCJ or mine?
- What did you do?
- Can you reproduce the problem with a simple "Hello World" application?

There really shouldn't be a libgcj.so.7 dependency. My Linux binaries 
never had that... So I guess you're doing something strange or ran into 
a bug...

[jnc-users] Binaries still need Runtimes?

[Norman <no...@sm...>]

Hello List,

when i try to run my JNC-compiled Java-Code on an different machine
without gcj installed, i get the error:


./AdminServer: error while loading shared libraries: libgcj.so.7: cannot
open shared object file: No such file or directory


I thought these binaries would need no runtimes or JRE any more.
Is this a mistake in my thinking or did i miss some settings to avoid this
and get a real stand alone application?

Well, not necessarily. You could also want to crosscompile for Linux ;-)

Ok, you didn't tell me if you want...
- a complete compilation or one for needed references only. I did a 
complete compilation (took 17 minutes on my laptop)
- an optimized compilation or one with debug info. So I did an optimized 
compilation.

Here you go: http://mtsystems.ch/tmp/swt-win.jar.o

Please note:
- You need to check the box for swt.jar. Otherwise swt.jar will be 
compiled because there's no cached archive for swt.jar which is for 
compilation with needed references only.
- You can't exclude AWT/Swing swing because the SWT-AWT bridge from swt 
needs it.
- When everything works as you with, you can drastically reduce the size 
of the final binary by compiling swt.jar so that only needed references 
are pulled in and by excluding AWT/Swing.

Re: [jnc-users] Reference not found

[Jerome B. <jbe...@ya...>]

Actually, this is not usually my habit. I am running
the demo version (which is my purpose here) and do get
the demo message. Simply when I first downloaded JNC,
it was the 1.0.1 version. I can't remember if I took
the gcj at the same time and it was version 4.2 or if
I took it from somewhere else, but I did not upgrade
it after moving to JNC 1.1.1. I''ll try with gcj 4.3
and let you know.
Thanks for your help,
Jerome

Well, you only told me that you use the current swt-3.2.2. You didn't 
tell me if you compile for Windows or Linux and if you want a complete 
compilation of swt.jar or one which only uses references. Also I need to 
know about optimization or debugging info.
So there are 16 possibilities and each will be about 10mb. Not to think 
about each time you update swt or downgrade because of bugs in the 
current version.
So I really would prefer if you could compile it yourself. Anyway, I 
could compile one to get you started...

Yeah, ~400mb Ram might be a little less. But still it should do... Did 
you try to increase the swap (might be called "virtual RAM" on Windows)? 
One or two gb should do ;-)

You don't need to compile your application to native just to give SWT a 
try. Just run it in a usual JVM...


> Where would I put [your]  cached swt...what folder?

The same as your swt.jar.

You're welcome...

I think mainly because no one optimized GCJ/GCC for speed... It become 
even worse with GCJ 4.3... Other reasons might be your processor, RAM 
and swap...
But you did notice that compiling swt.jar is only done once, right? It 
is cached in swt-[win|lin].jar.[a|o]. This will be reused in every 
compilation as soon as it exists...


> does it really have to

Yes, you don't know in advance which classes you need from swt.jar. Also 
what would happen if you took the cached swt.jar for another project?

[jnc-users] SWT compile issue

[Jer A <jer...@ho...>]

hello all, here is an SWT sample.
Why is it taking so looonnnnnnng to compile....does it really have to 
process the entire swt.jar? even for reference?

thanks in advance for all your help.

>>   I use JNC 1.1.1.

Had another idea about the "error: cannot find file for class 
javax.management.MBeanRegistration" problem:
You said you use JNC 1.1.1 and GCJ 4.2. So you probably took GCJ 4.2 
from somewhere else and copied some files to made the JNC GUI work and 
don't get the Demo alert, right?
Well, that's more or less ok with me, but you really should mention if 
you do something like that. Otherwise I start wondering why things don't 
work which really should. JNC 1.1.1 comes with GCJ 4.3 which seems to 
have support for the javax.management.MBean* classes. So, using 
"-findirect-dispatch" is in general a bad idea and you should update 
your GCJ.
Also I can only support my official releases. What happens if you work 
with GCJ 4.3? It would be good if you could add all your jars (not the 
big one) and compile them completely to check if compilation works at 
all. Later, you still can try to minimize the binary...
Never solve two unrelated problems at once ;-)

How much RAM do you have? What a CPU?
How do you compile? The complete Jar or only needed references? I think 
the problem shouldn't occur if you compile only needed references?
That GCJ needs a lot of RAM is a well known (and unfortunately ignored) 
problem. Try disabling optimization and maybe you also should manually 
increase the swap space of you machine.

Re: [jnc-users] Reference not found

[Jerome B. <jbe...@ya...>]

Hi Marco,
   
  I tried as you said with the -findirect-dispatch flag. I tried also without it by removing some classes from log4J.
  So I put all classes into a single jar and requested a full compilation of this jar. I tried three times and had to stop the process after it ran for 2 hours and took up to 600Mb RAM.
   
  Cheers,
  Jerome

That's bad. It means that you need an API that doesn't yet exist respectively is not complete. There has been a lot of work on javax.management lately, so it might work with the current GCJ trunk.
But of course that is no help right know. Try adding "-findirect-dispatch" as custom GCJ flag and hope you don't need the missing class at runtime.
Another thing that you might try is to remove the log4j jar from the compilation. I think log4j comes with GCJ/GNU classpath already.

Which JNC version?

Probably because you set most jars to only import needed references. 
With multiple jars, there will probably occur linking problems.
Technical explanation: This creates archives from your jars. At the 
linking step, some jars might need objects from an archive which has 
already been processed. So you get the missing references because the 
objects can no longer be found/imported.
This is already in my todo list...

What you can do about it:
- Extract all jars into a dir and create a new jar from this dir. That's 
what I usually do.
- Compile the complete jars.

I guess this jar needs to be compiled completely?!


Hope that helps
