problem with GCJ while running java code

[gforgcc]

Hi friends
I have a problem while running a java code with GCJ...
i recently cross compiled GCC for arm with added language option as java. so i got arm-unknown-linux-gnu-gcj..
My java code is

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

so i am crosscompiling my java code like this...
arm-unknown-linux-gnu-gcj -g --main=helloworld -o helloworld helloworld.java
and running like this
./helloworld
the above should print Hello World ! as far as my understanding since GCJ does not require JVM
while compiling and running it is not giving any error or warning..
but to some extent GDB helped me to atleast post here..
this is my GDB dump..

really dunno what is wrong why is showing those warnings.. as highlighted in the dump..
what is the meaning of all those..
please help me to solve this problem...
i just need it to print Hello World !
thanks... :) :)

We need to know

Exactly which gcc / gcj
Exactly which linux
Exactly which options you used to configure gcc / gcj

Thanks for the reply Andrew...

I am using DebianEtch linux OS for building the GCC-4.0.1 and have cross compiled it for ARM...
i have used the exact steps what is told in the below link.....

http://kegel.com/crosstool/crosstool-0.43/doc/crosstool-howto.html
(Have followed only till the completion of the Quick Start step... have not proceded further...)
and i am using gcc-4.0.1, glibc-2.3.2, core gcc as gcc 3.3.6, gdb-6.5 and have used glibc-linuxthreads-2.3.2 and linux-libc-headers-2.6.12.0
GCC_LANGUAGES="c,c++,java
The only thing i have used that is other than what is told in the above link is the Linux kernel..
i have used kernel-2.6.19-ts.at91sam9260ek.1
i.e. while configuring i have given the LINUX_DIR as the above path where the above kernel is present..

I recently finished the work to port gcj to ARM.  It was on
the new ARM EABI, not the "old" one (which is what I think you have).

http://wiki.debian.org/ArmEabiPort

gcc 4.0.1 may or may not work with gcj.  Sorry.

Andrew.

oh.. Great andrew... :) thanks again for the valuable info..
and can u please detail it """ what is new ARM EABI and what is OLD""" ?
is there something wrong in my configuring options ? or the only problem is GCC verison i am using ? or some any other reasons ?
and will you please suggest me what version of GCC can i cross compile for ARM architecture to get GCJ (cross compiled) to be working...
i.e. if i compile my java code using cross compiled GCJ (which will generate the executable for ARM) .. the executable should give the output.....
Please give me some links or share your knowledge regarding how to Cross compile GCJ for ARM with working version specifications and configuring options...
thanks again.. :)

That's why I posted the link.

I have no way to know.

Top of trunk, i.e. http://gcc.gnu.org/svn/gcc/trunk

Get it with

svn co http://gcc.gnu.org/svn/gcc/trunk

Cross compiling for ARM Linux is easy.  Here's how to do it on
Fedora 8.

You already have a cross-linker, assembler, etc.  Make sure they're
in your path.

Download http://ftp.linux.org.uk/pub/linux/arm/fedora/rootfs/rootfs-f8.tar.bz2
and unpack it:

cd /local/x-arm-gcc/rootfs-f8
tar xf ~/rootfs-f8.tar.bz2

In the top level directory of the gcc source, do:

./contrib/download_ecj

Build gcc in a clean directory with --with-sysroot= pointing at your ARM
root filesystem:

/home/aph/gcc/trunk/configure --prefix=/local/x-arm-gcc/install \
--with-sysroot=/local/x-arm-gcc/rootfs-f8 --disable-libssp --disable-libgomp \
--disable-libmudflap --enable-libgcj --disable-bootstrap --disable-multilib \
--disable-static --disable-sjlj-exceptions --target=arm-linux-gnueabi --enable-languages=c,c++,java

make

make install

This should work equally well for Debian, etc.  You can use the root FS
from any ARM EABI Linux system.

Testing, first compiling on the x86 host:

$ /local/x-arm-gcc/install/bin/arm-linux-gnueabi-gcj Hello.java  --main=Hello

And then running on the target, with the a.out we just made:

$ ./a.out
Hello, World!

Andrew.

woow... very useful info... :) :) i will try all these things and get back if i have some problems regarding this...
thanks... :)

Hi Andrew
i faced some problems while building when i tried the above steps what you told.. Here is the log of the error messages..(I have configured with the options as you have told above.)

current directory is /home/developer/downloads/build_dir

../gcc-4.0.1/configure --prefix=/home/developer/downloads/install_gcc_dir
--with-sysroot=/home/developer/downloads/rootfs-f8 --disable-libssp --disable-libgomp
--disable-libmudflap --enable-libgcj --disable-bootstrap --disable-multilib
--disable-static --disable-sjlj-exceptions --target=arm-linux-gnueabi
--enable-languages=c,c++,java

and then did a make in the /home/developer/downloads/build_dir

after sometime it gave these error messages...

You're picking up the assembler for your host machine, not the cross-assembler
for your target.

When you run configure, make sure that your target binutils are in the PATH.
Alternatively, you can use --with-ld=, --with-as=, etc.

The output of configure will tell you which ld, as, etc. it's using.  Make sure
these are the target versions.

oh.. ya thanks for that info Andrew...:)
and again it is giving some other problems...

i configured --with-ld=<ld in the rootfs-f8 usr/bin/ folder> i.e. --with-ld=/home/developer/downloads/rootfs-f8/usr/bin/ld
and similarly for --with-as --with-ar --with-nm too.....

during the time of compilation after sometime it tells
/scratchbox/tools/bin/misc_runner: /targets/links/scratchbox.config: No such file or directory :(
(is this because i am running outside scratchbox ?)

and when i tried running inside scratchbox it is telling
/lib/ld-linux.so.3 not found...

how to proceed further ?
thanks again.. :)

Eh?  Surely those versions won't run on the host machine.  These are
for the target.

Is the root fs you built the x-compiler with the same as the root
fs you're running on?

Hi Andrew,

thanks for your hint.

I'm getting this error when I do make:

../.././gcc/config/arm/arm.c: In function ‘thumb_find_work_register’:
../.././gcc/config/arm/arm.c:3567: error: ‘struct function’ has no member named ‘args_info’

Config:

./configure --prefix=/root/tmp/f8/install --with-sysroot=/root/tmp/f8/rootfs-f8/ --disable-libssp --disable-libgomp --disable-libmudflap --enable-libgcj --disable-bootstrap --disable-multilib --disable-static --disable-sjlj-exceptions --target=arm-linux-gnueabi --enable-languages=c,c++,java --with-build-time-tools=/root/tmp/f8/rootfs-f8/usr/bin/

I'm doing this with Kubuntu (2.6.22.4), does it matter? should I try with fedora 8?

When I said "Build gcc in a clean directory" above *I really meant it*.

Don't configure in srcdir.  I don't know if this is the cause of your
problem, but don't do it.

That shouldn't make any difference.

Wow I managed to compile arm-linux-gcj, thanks a lot for your help.

However I'm getting this error when I try to compile a java class:

./arm-linux-gnueabi-gcj /root/testfiles/HelloWorld.java

arm-linux-gnueabi-gcj: error trying to exec 'ecj1': execvp: No such file or directory

I did /contrib/.download_ecj before doing configure and make

Any ideas?

Thanks again,

Francesco

download_ecj will obtain the required ecj JAR file.  ecj1 is a script
or binary that executes the GCCMain class in this  First check that
there isn't one in your GCJ build, but not on your path.  If you can't
find one, a script called ecj1 containing:

#!/bin/sh

gij --classpath <path to ecj.jar> \
   org.eclipse.jdt.internal.compiler.batch.GCCMain \
   ${1+"$@"}

or

gcj -oecj1 --main=org.eclipse.jdt.internal.compiler.batch.GCCMain ecj.jar

should suffice. gcj depends on ecj1 for source to bytecode compilation.

Thank you very much Andrew, I really appreciate your help.

I did ./arm-linux-gnueabi-gcj -oecj1 --main=org.eclipse.jdt.internal.compiler.batch.GCCMain ecj.jar

but now I'm getting this error:

Works for me.  Maybe you have an old version of as?  What does

  as -version?

say?  

What does

  arm-linux-gnueabi-gcj -verbose -save-temps -oecj1 --main=org.eclipse.jdt.internal.compiler.batch.GCCMain ecj.jar

say?

Andrew.

Hi,

Which "as" are you referring to?

The one in my /usr/bin says:

while the one in my toolchain (/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin says:

 I guess gcj is using the one from /usr/bin. Is this correct?

Thank you,

Francesco

Obviously not, no:

> This assembler was configured for a target of `i486-linux-gnu'.

Ah, your gcc target and your as target don't match.  arm-linux-gnueabi and
arm-linux-uclibcgnueabi; this is bad.  It's really important to configure
binutils and gcc for the *same( target.

Anyway, you should be able to get it to work by making sure your PATH is set
correctly when builfing for ARM.

Andrew.
