Yes, in ubuntu /usr/bin/i686-linux-gnu-gcj points to /usr/bin/gcj-x.x where 
x-x is the version. Even /usr/bin/gcj points to /usr/bin/gcj-x.x (so the 
debian update-alternatives script can make you choose among versions simply 
modifying the /usr/bin/gcj link).
The link I made (i686-pc-linux-gnu-gcj) points to 
/usr/bin/i686-linux-gnu-gcj that points to /usr/bin/gcj-x.x .

A question: especially for prerequisites and dependancies, are there 
specific instructions when cross-compiling for windows? Should I consider 
http://kegel.com/crosstool/ as the main reference?
Thanks!

I can guess, but I don't really know.  Windows, thank heaven, is something
I haven't had to touch for a long time.

MessageBundle ???

[dj_def]

I did other tests: I compiled gcc-4.3.0 (with 4.6 and 4.7 I was unable to 
compile because of libltdl errors and missing jvm.exe) correcting 
Formatter.java and with --enable-maintainer-mode.
To make it succesfully I had to

1) sudo ln -sf /usr/bin/i686-linux-gnu-gcj /usr/bin/i686-pc-linux-gnu-gcj
(I did this because during some gcc configuration process, it detects 
/usr/bin/i686-pc-linux-gnu-gcj instead of /usr/bin/i686-linux-gnu-gcj...
it could be some ubuntu packaging issue as before compiling I installed the 
whole gcc ubuntu package...)


2) gcj 
/pathToSrcDir/gcc-4.3.0/ecj.jar -findirect-dispatch --main=org.eclipse.jdt.internal.compiler.batch.GCCMain 
 -o ~/moveinecj1
   sudo mv ~/moveinecj1 /usr/bin/ecj1
   sudo chmod +x /usr/bin/ecj1
(this should be a known issue when cross-compiling)

Well... with this version there is not any "MessagesBundle.properties 
missing resource problem" but the previous problem is not completely solved:

class Test {
  public static void main(String argv[]) {
    System.out.printf("%09.3f%n",3.1415926535);
  }
}

this time the program does not crash but also does not print anything (it 
could be normal as now it uses parseInt).

The other test with the openConnection() function now succeeds :)
I did as you told me:
gcj --resource java/util/iso4217.properties -c 
pathTo\libjava\classpath\resource\java\util\iso4217.properties -o 
iso4217.properties.o

Thank you for all!

It should just detect /usr/bin/gcj .  What is i686-pc-linux-gnu-gcj doing is
/usr/bin anyway?

I don't quite see what the problem is here.  Yes, you have to have ecj1
to build with --enable-java-maintainer-mode.

I already said, I think.  Formatted floating-point output has not been written.

Re: MessageBundle ???

1)
There is this test that is working under gcc 4.3.0 compiled by me with
ecj1.exe created under ubuntu linux 11.04 (with i686-pc-mingw32-gcj
cross compiler).
This same test is not working with thisiscool gcc 4.3.0 (eclipse):
import java.util.*;
import java.util.regex.*;
public class Test {
  static public void  main (String[] argv) {
    String s = new String("hom hom");
    String t = new String("om");
    String u = s.replaceAll(t, "i Jack!");
    System.out.println(u);
  }
}------------->gives: java.lang.NumberFormatException: invalid character
at position 1 g$ò< ...


2)
This other test is not working with both the versions.

class Test {

   public static void main(String argv[]) {

       System.out.printf("%09.3f%n",3.1415926535);
   }
}

-------------> gives a: Exception in thread "main"
java.lang.NumberFormatException: invalid character at position 2 in 09


3)
This last test works with thisiscool gcc and not with the gcc I
compiled:

import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class LastTest {
  public static void main(String args[]) {
    try {
      URL url = new URL("http://www.google.it");
      url.openConnection();
    }
    catch(Exception e) {

WTH!!! Is this an April's fish? :D
I would like to have working connections and working replaceAll at the
same time... is it possible? :)
Are we facing the same problem of previous mail or this is another
problem?
How could this be solved? Please save me! 


ps. I could get rid of the MessageBundle problem linking everytime a
libgcj.o created with gcj --resource
gnu/java/util/regex/MessagesBundle.properties C:\wgcc\share\java
\libgcj-4.3.0.jar and then compiling the application with: gcj

That's just a bug: leading zeroes in format fields aren't being handled
correctly.  The "09" is being parsed as an octal number because it begins
with a zero.

This will be another missing resource, I expect.

Here's the actual exception

Look at Currency.java:136

        properties.load(Currency.class.getResourceAsStream("iso4217.properties"));

So you need to link iso4217.properties.o

The fix for the exception is

I just had a look, and as far as I can tell floating-point formatted
conversion has never been implemented in gcj.  Sorry.

Coincidentally the exact same problem and fix were discovered by Pekka
and went into GNU Classpath recently.

2010-02-16  Pekka Enberg  <penberg@kernel.org>

        * java/util/Formatter.java:
        (parseInt): Use Integer.parseInt() insted of Integer.decode()
        because the latter doesn't work with leading zeros which are
        used in String.format() formatting, for example.

gcc is in Stage 1, so we could just bulk-import Classpath.

What do you think?

MessageBundle ???

[dj_def]

I have problems with all java programs containing regex and string
functions like split() or replace()/replaceAll().
This programs will compile and run correctly on linux but will compile
and crash on windows; the output says something about a missing resource
(MessageBundle). I tried many things to get around of this but I did not
find any solution.
I would like to better understand why this happens but the most
important thing would be to find a solution.
I use this class as an example:

import java.util.regex.Pattern;
class FFooClass {
  public static void main(String args[]) {
    Pattern p = Pattern.compile("bye");
    System.out.println("bye");
  }
}

I do:
gcj --main FFoo.java -o FFoo
on linux and it works!
I do:
gcj --main FFoo.java -o FFoo.exe
on windows (or even with a cross compiler for linux) and the app
FFoo.exe doesn't work!
Starting from this class, what are the steps to get a working exe?

The problem here is that the linker doesn't know that a MessagesBundle
is required.  The core cause of all this is that dynamic linking still
doesn't work for gcj on Linux.

You need to link explicitly on the command line with the MessagesBundle
files.  Look for something like

   gnu/java/util/regex/MessagesBundle.properties.o

in the libcgj build dir.
