Hi all,

The last couple of days i have been trying to get a sample of the
sleepycat xml database to work.
Unfortunately, running the example keeps throwing a
UnsatisfiedLinkError at me. Solutions in old message threads
addressing the same issue did not solve this problem.

SuSE linux 9.1 for amd64 runs on my machine with a 2.6.5 kernel. I
practiced the same routine on a SuSE 9.1 Pentium IV machine with
exactly the same result. Tried Java versions 1.4.2 and 1.5.0.

build dir: /root/tmp/dbxml-2.0.9
deploy dir: /opt/bdbxml-2.0.9

- building xml db: ./buildall.sh -b 64 --enable-java
- moved files from builddir/install to deploydir/
- added deploydir/lib to /etc/ld.so.conf
- ran ldconfig
- ran ldconfig -p | grep dbxml. result was
libxquery-1.0.so (libc6,x86-64) =>

- set CLASSPATH to
/opt/bdbxml-2.0.9/lib/db.jar:/opt/bdbxml-2.0.9/lib/dbxml.jar:/opt/bdbxml-2.0.9/lib/dbxmlexamples.jar
- set LD_LIBRARY_PATH to /opt/bdbxml-2.0.9/lib
- created a default container using dbxml_shell /opt/bdbxml-2.0.9/db

- ran an example:
java com.sleepycat.dbxml.examples.gettingStarted.exampl eLoadContainer
-h /opt/bdbxml-2.0.9/db -p /opt/bdbxml-2.0.9/examples/xmlData/

At this point i am at a loss. Why does it complain about a missing lib,
even it is acually there?

Any help is appreciated
Milo

Hi Milo,

Can you try this?

ldd /opt/bdbxml-2.0.9/lib/libdb_java-4.3.so

I'm not sure why this is failing, but it may be because you moved the
files from the installation directory by hand. It's usually simpler to
set the installation directory with '--prefix=...' when you run the
buildall.sh script.

Regards,
Michael.

Hello Michael,

Thanks for your response.
Just made a clean build and install using the buildall script with a
--prefix parameter setting, as you suggested.
The result is the same. Running an example ends up with the same
exception.

output ldd /opt/bdbxml-2.0.9/lib/libdb_java-4.3.so:

libpthread.so.0 => /lib64/tls/libpthread.so.0 (0x0000002a95768000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a9587d000)
/lib64/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2
(0x000000552aaaa000)

If you are interested in the logfiles of the latest build, I can send
them to you.

Kind regards
Milo
