I am having run-time link problems with my java app. I am using the
Blackdown 1.4 Java SDK on testing. When I try to run my app, I get:
$ ./jvm_dump_system_property
./jvm_dump_system_property: error while loading shared libraries: libjava.so: cannot
open shared object file: No such file or directory
So the first step is to see what ldd says:
$ ldd jvm_dump_system_property
libjava.so => not found
libjvm.so => /usr/lib/j2se/1.4/jre/lib/i386/server/libjvm.so (0x40023000)
libverify.so => not found
libc.so.6 => /lib/libc.so.6 (0x4068c000)
libnsl.so.1 => /lib/libnsl.so.1 (0x407bb000)
libm.so.6 => /lib/libm.so.6 (0x407d0000)
libdl.so.2 => /lib/libdl.so.2 (0x407f2000)
libpthread.so.0 => /lib/libpthread.so.0 (0x407f5000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
Where we can see that libjava.so cannot be found.
I have modified the ld configuration file (and I am not sure why the
package install did not do so):
$ cat /etc/ld.so.conf
/usr/X11R6/lib
/usr/lib/atlas
/usr/lib/j2se/1.4/jre/lib/i386
/usr/lib/j2se/1.4/jre/lib/i386/server
We can see that ldconfig seems to know where libjava.so is (as well as
libjvm.so, which ldd did find):
$ ldconfig -p | grep 'libjava.so\|libjvm.so'
libjvm.so (libc6) => /usr/lib/j2se/1.4/jre/lib/i386/server/libjvm.so
libjava.so (libc6, hwcap: 0x1000000000000) =>
/usr/lib/j2se/1.4/jre/lib/i386/libjava.so
The only suspicious part is the hwcap value.
Here are the java packages that I have installed:
$ dpkg -l 'j2*'

Some messages I have seen on the net hint that the version of libc may
be important as well, although they seem to refer to libc6-2.2 and
j2re-1.3:

And here is where I am getting them from:
$ cat /etc/apt/sources.list

And I am at testing:
$ cat /etc/apt/apt.conf

Any help would be appreciated.
