Blackdown J2se On Zaurus Sl-c3000, Not found: libjava.so Options

[daniel3000]

Did anyone try this already?

I downloaded an IPK package which has been designed for the iPaq (from http://www.tml.tkk.fi/~jsantala/feed/ ).

It could not be installed to the SL-C300 with ipkg install, because ipkg tried to install files on on eof the read-only file systems. So I disassembled the package manually with tar.

What I got was mainly a directory

./j2re1.3.1/bin and
./j2re1.3.1/lib

Calling ./j2re1.3.1/bin/java I got
"Error: Can't find libjava.so".

libjava.so is in ./j2re1.3.1/lib/armv4l/libjava.so.

So I linked it to /usr/lib and called ldconfig. but still the same error.

Could anyone please guide me what to do in order to make blackdown J2SE work on the SL-C3000?

Thanks

The java wrapper script needs some hacking to get it to work.

Hi Meanie,

tried it per your instructions, unfortunately still some problems. Java won't start.

What i did:

Using the blackdown-jre_1.3.1-RC1_arm.ipk:
Installing with ipkg didn't work, since it wanted to install to some read-only places.

* So I untarred the ipk and the data.tar.gz and got a j2re1.3.1 directory with bin and lib in it. Started from there.

* Copied the j2re1.3.1 to /usr/local (i.e. /hdd2/usr/local).

* Used your instructions:
# ln -s /usr/local/j2re1.3.1/bin/java /usr/bin/java
# ln -s /usr/local/j2re1.3.1/bin/armv4l /usr/local/j2re1.3.1/bin/armv5tel
# ln -s /usr/local/j2re1.3.1/lib/armv4l /usr/local/j2re1.3.1/lib/armv5tel
# ln -s /usr/lib/libstdc++-3-libc6.1-2-2.10.0.so /usr/lib/libstdc++-libc6.2-2.so.3

Had to do a chmod a+x /usr/local/j2re1.3.1/bin/java in addition.

Now, starting "java", I get the following errors:

/usr/bin/java: /bin/realpath: not found
(where can I get this tool?)

grep: /lib/jvm.cfg: NO such file or directory
(where does this file come from normally?)

java was not found in /bin/armv5tel/native_threads/java
(not even /bin/armv5tel exists - why does it think it should be there?)

Thanks for all further hints!

Hi Daniel,

I've tried this under Pdaxrom and it worked (I can't remember where i found it) :

"download blackdown's arm version of J2SE 1.3.1
decompress the blackdown archive in /home/root/usr/local
run 'uname -m' to determine the machine hardware name

Blackdown expects 'armv4l' as hardware name, in my case the one that
'uname -m' returned was 'armv5tel'. In order to fix that i had to add
the following symbolic links:

ln -s /home/root/usr/local/j2re1.3.1/bin/armv4l /home/root/usr/local/j2re1.3.1/bin/armv5tel
ln -s /home/root/usr/local/j2re1.3.1/lib/armv4l /home/root/usr/local/j2re1.3.1/lib/armv5tel
now you need to install the following additional libraries: libBrokenLocale.so libXm.so libXp.so libstdc++-libc6.2-2.so.3

the first 3 can be found in additional-ipaq-stuff.tar.gz on
blackdown's website I got libstdc++ from here (
http://intimate.handhelds.org/installer ... 6.2-2.so.3 )

you can copy the libraries in any directory, you'll have to add the directory path to /etc/ld.so.conf

then execute ldconfig
now you can add /home/root/usr/local/j2re1.3.1/bin to the path"

Tell me if it works for you,
