Re: [jnc-users] JNC version 1.1.1 only works with version 1.1 backend

[<ge...@no...>]

Dear Marco,

thank you for answering so quickly!

> Sounds like the problem explained in the Manual.

Not really. The lines in the manual on SWT are about a problem that
occurs when one is already able to work with SWT on JNC. But it only
took me another night to find out what must be done to get there:

- Download swt-4.4M4-win32-win32-x86.zip from
   http://download.eclipse.org/eclipse/downloads/drops4/S-4.4M4-201312121600/
- From that archive, extract swt.jar and add its name to the
   bottom box on the "Step 1" page (now I see the checkbox).
- From swt.jar, extract swt-win32-4413.dll and move it to the "lib"
   subdirectory of the folder where the executable is compiled to.

Then the SWT "Hello World" example can be compiled without any problems,
and the created binary works as expected. Too trivial for a manual or
FAQ? Not for a beginner.

Maybe one day you change your mind about abandoning your work that
appears to be so useful after one has overcome the very first problems!

I'm not maintaining JNC anymore. Either it works out of the box for you 
or you have to look for another solution. The only other native compiler 
I know is Excelsior Jet. It's a full blown native compiler that will 
work for you, but it is not exactly cheap.
But maybe wrapping your program into a binary instead of real native 
compilation will be sufficient for your case. There are many solutions 
doing that.
And I don't think you will waste time learning Java. It doesn't matter 
if you will be using it as your main language or not. The more languages 
you know, the better a programmer you will be (and the easier it will be 
to learn even more programming languages).

This is a known thread race problem (meaning I know about it). AWT has a 
bug that happens to work with the threading implementation of the 
Sun/Oracle JVM. But actually it shouldn't according to the Java 
threading specs which are how GCJ implemented it. The GCJ guys actually 
wanted to implement it the Sun/Oracle JVM way but have a bug that makes 
it only compatible with the threading specs.

Sounds like the problem explained in the Manual.

If I understand you right, then you mean that the AWT examples start 
with the older GCJ version, but not with the newer GCJ version 
(compilation works in both). This is the problem I explained above; a 
thread race. The problem exists in both JNC/GCJ versions. Mostly the GUI 
won't open, sometimes it will. Seems for you it just happened to opened 
with the older version (probably due to the smaller binary).

> I do not hear a "beep when done",

Maybe the beeping offered in the old SWT version used for the JNC GUI 
doesn't work with the latest Windows/Debian releases. Or maybe your 
internal speaker is disabled/nonexistent. Doesn't sound too critical to me.

I see checkboxes:

I'm not maintaining JNC anymore. Also I think GCJ is not maintained anymore.

It sounds to me that it's not worth the time. If you learn one (or 
better: multiple) programming languages without worrying about 
compilation, your time will probably be invested better.

[jnc-users] JNC version 1.1.1 only works with version 1.1 backend

[<ge...@no...>]

Dear Marco,

being a newbie, I first wanted to make sure that I can produce
executable binaries before I waste too much time learning Java,
so I spent half a week playing with your JavaNativeCompiler
version 1.1.1, together with GCC version 122233, as linked on your
download page. I use Windows 7 and Debian 7.3 (64 bit both).

1. There were no problems compiling a "Hello World" program that
writes directly to the console using the "System.out.println"
command; the created binary worked as expected.

2. This was not the case, however, with a "Hello World" program
using AWT:
http://www.xinotes.org/notes/note/1105/
Here I ran into a problem similar to that one "Cyber Legionnaire"
described on September 24th, 2006:
> I've compiled some source files using JavaCompiler. The .EXE is  
> created but when I try to run it, I briefly  see a blank console  
> window and the program terminates. No error message, no nothing.
http://sourceforge.net/mailarchive/forum.php?thread_name=45178178.4090807%40gmx.ch&forum_name=javacompiler-users
In my case, I just saw the "Demo" message box, and the Windows
task manager listed a running 40 MB process, but no "Hello World"
window was visible.

3. The same thing happened when I compiled the AWT text editor
example. I thought I must have made a silly mistake concerning
the installation folders or the JNC settings, but then I noticed
that the archive already contained pre-compiled binaries - and
these ones failed in the same way, on both Windows and Linux!

4. As you recommend using SWT stating that it is fully supported
while AWT and Swing support is still experimental, I tried to
compile a "Hello World" program using SWT:
http://www.mkyong.com/swt/swt-hello-world-example/
Here I inevitably got "import cannot be resolved" error messages.
So in the FAQ a hint for the newbies on how to use SWT with JNC
would be helpful.

5. Then I finally had luck running the binary that comes with
the 1.1 version of the AWT text editor example. I noticed that
the process now was only 30 MB large in the task manager listing,
though the source file was the same as in the 1.1.1 version. So
I supposed that this might be caused by the involved GCC, which
is version 121694 here. And when I simply downloaded that older
version of GCC and used it with JNC 1.1.1, (nearly) everything was
just fine: I suddenly could compile the AWT "Hello World" program
and the AWT text editor, and both showed up as desired! (Okay, the
letters were missing in "Hello World"... but what a success!)

I got the impression that you made a severe mistake in "bundling" a
somewhat buggy GCC with your latest version of JNC, over the years
possibly disappointing lots of prospect customers who made the same
experience as I did. By the way, I do not hear a "beep when done",
and I do not understand the line "Checkbox: Compile compete jar"
on the "Step 1" page since there is no checkbox. So what about
a version 1.1.2 bugfix to state that JNC is still alive? And will
you continue working on JNC when there is some progress with GJC?
On my side, I think I will continue "playing" with JNC. I like it.

Regards,

Gerolf

All JNC releases are on sourceforge. I don't remember the specifics of 
each of them. Just check the release notes and try for yourself.

Re: [jnc-users] Help with figuring out additional Jars referenced by the Third-Party Jars included in a project

[Marco T. <ma...@mt...>]

Dear Hirak

You can try two things:
- Don't compile the complete jar (step 1).
- Add "-findirect-dispatch" as custom GCJ flag (step 3). This way you 
don't have to provide the missing jars.

Hope that helps

[jnc-users] Help with figuring out additional Jars referenced by the Third-Party Jars included in a project

[Hirak B. <hir...@gm...>]

Hi,

I'm attempting to generate an executable for a Spring application. I am
packaging my compiled source code into a jar. This jar along with the spring
jars are added to the JNC project. However, when I try to compile, it throws
an error trying to process the spring.jar.

It appears as though the compiler requires additional jars(like aspectjrt)
that Spring references in its source, but those are not required if I simply
run my application as a Java application. Can someone please confirm if this
is expected?

If so, then is there a way to compute the complete list of referenced jars?
Just trying to find out if there's any way, other than trying to compile
repeatedly and adding jars one at a time.

Thanks,
Hirak

Well, delete the lib directory and press compile again ;-)
The message is only shown at the first compilation when the additional 
files are being copied. At least as far as I remember... It's quite a 
while ago I programmed that.

There's a thread race in GCJ. AWT is almost always running into it. SWT 
is working much better...

Re: [jnc-users] Problem of "multiple definition of..." compiling with Spring, Xalan

[Marco T. <ma...@mt...>]

Hey Kamesh

If you have the same classes in multiple jars, then the cleanest thing 
to do would be to delete them in all except one jar.
Anyway, you're probably looking for a workaround. So, adding 
"-Wl,--allow-multiple-definition" as custom compilation flag should do 
the trick.


Hope that helps

[jnc-users] Problem of "multiple definition of..." compiling with Spring, Xalan

[Kameswara R. B. <B.K...@ig...>]

Hi,

My program uses Spring and  Xalan libraries. I am using latest JNC to compile my program on Windows into an exe. When I check the checkbox "Compile complete jar", it gives me errors like "multiple definition of...".
Example:
multiple definition of `org::w3c::dom::xpath::XPathException::XPathException(short, java::lang::String*)'
 /lib/xalan-2.5.1-win.jar.o:xalan-2.5.1.jar:(.text+0x579520): first defined here
 /javanativecompiler-1.1.1/javanativecompiler-1.1.1/gcc-122233-win/bin/../lib/gcc/i686-pc-mingw32/4.3.0/../../../libgcj.a(org-w3c.o): In function `ZN3org3w3c3dom6events14EventExceptionC1EsPN4java4lang6StringE':/usr/local/src/gcc/libjava/classpath/external/w3c_dom/org/w3c/dom/events/EventException.java:24: multiple definition of `org::w3c::dom::xpath::XPathExpression::class$$'

If I do not check the Checkbox, the xalan libraries are not included in my executable since they are invoked dynamically by Spring.

Can anyone please let me know how to resolve this issue. Is there a way to mention the compiler to take one of the definitions (both are same) but only exist in different jar files.

Thanks,
Kamesh

Thanks very much for your time Marco,

I'll update this thread when I do find whatever the solution is. It could 
well be simply switching to another parser!

I don't remember how I implemented it, sorry. So if the order in the GUI 
is not maintained in the compilation, then you could adapt the sources 
for the GUI frontend. Shouldn't be too hard...
But I think you're trying to ride a dead horse here. You already have 
all objects in your binary. You have nothing else to add that might help...


Hope that helps
Marco

Indeed, so am I correct though that it is impossible to control the order of 
the Custom GCJ Flags in JNC? 

Re: [jnc-users] NullPointerExceptionatjava.net.URLClassLoader.getPermissions

[Marco T. <ma...@mt...>]

Dear Keith

Then the problem is more complicated and requires a closer look at the 
compilation and the GCJ source... So I'm afraid I can't help you since, 
as you already discovered, I discontinued JNC.
Of course you could also try to use another xml library...


Sorry for the bad news
Marco

[Keith B. <kei...@fl...>]

Hi Marco,

You're too fast at replying. Sorry I should have made myself more clear. I 
have done your suggestion and that is the error that I get now I've done as 
you said.

Here's a dump of the options that give me this error:

gcc-122233-win\bin\gcj
		--main=com.flare.applications.FileSquirrel.App
		-fjni
		-Djava.library.path=lib
		-Dsun.java2d.fontpath=

		-Dawt.toolkit=sun.awt.windows.WToolkit
		-Dsun.io.unicode.encoding=UnicodeLittle
		-Llibs/win
		-Ilibs/win/gui/gui.jar
		-oC:\JavaNC\projects\FileSquirrel\compiled\filesquirrel.exe
		-s
		-O2
		C:\JavaNC\projects\FileSquirrel\lib\*
		-Wl,--allow-multiple-definition
		-findirect-dispatch
		-ljncTrial
		-IC:\Users\Keith Boynton\Documents\EclipseWorkspace\File 
Squirrel\bin\fileSquirrel.jar

		-IC:\JavaNC\projects\FileSquirrel\jars\dom4j-1.6.1.jar
		@C:\Users\KEITHB~1\AppData\Local\Temp\JNCTempnmusjg.out\SourceListnmusjh.list


Note. C:\JavaNC\projects\FileSquirrel\lib\* is the location where I 
extracted the objects to (it was c:\temp\templib\* in our previous 
discussions).

Doing your suggestion did get me past the previous NoClassDefFound error 
(org.xml.sax.EntityResolver) but now I'm battling with this one:
Exception in thread "main" java.lang.NoClassDefFoundError: 
java.text.DecimalFormat
   at gnu.xml.transform.Stylesheet.initDefaultDecimalFormat

The GCJ folks reckon it was something to do with the properties objects 
hence their suggestion:
http://gcc.gnu.org/ml/java/2009-11/msg00084.html

I appreciate your time Marco, especially as I know you've discontinued your 
work on JNC for now.

Re: [jnc-users] NullPointerExceptionatjava.net.URLClassLoader.getPermissions

[Marco T. <ma...@mt...>]

Dear Keith

Pleas read my previous mail again and do what I wrote there (extract 
libgcj.a (e.g. to "D:\only_libgcj_tmp") and add all objects to the 
compilation (flag "D:\only_libgcj_tmp\*")).
This way - as already said - all libgcj objects will end up in your 
binary and you can test if it works. If it does, you can slowly remove 
the object you don't need (or the other way around).
You seem to have made your live unnecessary complicated with the current 
problem :-( The solution to the xml problem already solved this...

Ah yeah, if you're working on Linux, the "*" will not work in 
"D:\only_libgcj_tmp\*". So you might want to edit the JNC config file 
yourself and add all objects to it.


Hope that helps
Marco

[Keith B. <kei...@fl...>]

Hi Marco,

That certainly does help, I'm a little further down the road and am battling 
with the following error now.

Exception in thread "main" java.lang.NoClassDefFoundError: 
java.text.DecimalFormat
   at gnu.xml.transform.Stylesheet.initDefaultDecimalFormat(win32.exe)

I've asked a few questions on the java-gcc mailing list, they've been very 
helpful and have suggested the following:

#copy libgcj to a working dir (could be in a different location than 
/usr/lib/ for you)
mkdir -p /tmp/mess_with_libgcj
cd /tmp/mess_with_libgcj
cp /usr/lib/libgcj.a .

#extract all the object from this library
ar x libgcj.a

#make a lib with only the properties objects
ar rvcs libgcj_properties.a *properties*.o
#do the (sometimes superfluous) blessing of the lib
ranlib libgcj_properties.a

#copy the lib to the system lib dir
cp libgcj_properties.a /usr/lib/

#goto your source project and this time link-in those properties objects 
with --whole-archive, this forces the linker to include them even if they 
aren't statically referenced
cd <your source build-tree>
*gcj* -o <your 
prog> -Wl,--whole-archive -lgcj_properties -Wl,--no-whole-archive -static-libgcj 
 --main=<your main>



Now, I've tried add the flags 
(-Wl,--whole-archive -lgcj_properties -Wl,--no-whole-archive) to the Custom 
GCJ flags section. However I can't seem to add them in the correct order. 
JNC seems to re-order them for me and it ends up:
-Wl,--whole-archive -Wl,--no-whole-archive -lgcj_properties

Is this a restriction or am I missing something?

Keith
