Trouble Invoking JVM From C: Cannot Find libjava.so.
 

I'm trying to compile and run the code from the tutorial at
http://java.sun.com/docs/books/tutor...king/invo.html
(invoking the Java Virtual Machine from C), and am running into problems.
My setup is:

• Slackware Linux 9.0 with kernel 2.4.20
• gcc 3.2.2
• J2SE 1.4.2_01

The tutorial says to compile (on Solaris) using:

so I try using:
The first error from that attempt is "In file included from
invoke.c:1: /usr/local/j2sdk1.4.2_01/include/jni.h:27:20:
jni_md.h: No such file or directory"

So I find the directory that jni_md.h is in and add that to the compile:
The first error from that attempt is "/usr/lib/gcc-lib/i386-slackware-linux/3.2.2/../../../../
i386-slackware-linux/bin/ld: warning: libjvm.so, needed by /usr/local/j2sdk1.4.2_01/jre/lib/i386/libjava.so, not found"

So I find where libjvm.so is located and add that to the compile:
The first error from that attempt is STILL "/usr/lib/gcc-lib/i386-slackware-linux/3.2.2/../../../../i386-slackware-linux/bin/ld: warning: libjvm.so, needed by /usr/local/j2sdk1.4.2_01/jre/lib/i386/libjava.so, not found"

So I spend a while to find out how Linux handles libraries, and decide to add the two library directories to /etc/ld.so.conf and run /sbin/ldconfig. Then I try to compile using the same compile command as before:
Great! No errors! So let's see if this thing runs:

Now I get the following error: "./invoke: error while loading shared libraries: libjava.so: cannot open shared object file: No such file or directory"

I confirm that libjava.so file is in /usr/local/j2sdk1.4.2_01/jre/lib/i386/ and that my /etc/ld.so.conf is correct:

I decide to look at the shared library dependencies of invoke:

This gives me:

Notice that libjava.so is not found even though it is in /usr/local/j2sdk1.4.2_01/jre/lib/i386/ (which is in my /etc/ld.so.conf and also indicated to the compiler using the -L flag.)

What am I missing????

Thanks!

Update: some additional information. When I use ldd to examine libjava.so it says it cannot find libverify.so even though libverify.so is in the same directory as libjvm.so:

When I use ldd to examine libverify.so, everything looks fine:
