Runtime error after compiling and linking functions containing XDK calls

Question

We have a preexisting application in C distributed across multiple shared objects - on HPUX.
$ORACLE_HOME/xdk/include was included in the include path and the programs were compiled. Linking also was successful.
However at runtime we get errors of the form:
/usr/lib/dld.sl: Unresolved symbol: XmlCreate__FP6xmlerrPUce (code) from ./lib_my_so_name.so
Clearly it's not able to locate the shared libraries corresponding to the xdk since XmlCreate() is not getting resolved.
Where would these libraries be, what are their names on HPUX, and are they installed by default? If not is the installation procedure documented anywhere.
We'll need this information for both HPUX and AIX.

Answer 1

* Don't post that much code. There should never be a reason to. You should be able to break your code down into small enough pieces that you can post a small example that demonstrates your problem.
* When you do post code, use [code] and [/code] tags to make it readable. You can use the code button on the message entry page.
* The stack trace will tell you which line the NPE occurred on, where it was called from, where that was called from, etc. You can use that to help you find your error. Look at the line it's complaining about. What references are on that line followed by a dot, and what arrays do you try to access the elements of. One of those must be null.
* Now that you know what[b] is null, put in a bunch of print statements to track [b]how it got to be null.
