Hi, I am trying to run my application (32-bit) on HP-UX 11.22i (64-bit)
and am getting the above message while dynamically loading libdb2.so
from my application. I am using dlopen as follows:

dlopen(libName, RTLD_NOW);

I have looked up notes from DB2 that say that as long as I link with
32-bit DB2 libs, the application should work. I have made sure I have
32-bit DB2 libs in the SHLIB_PATH and also made sure that my
application is built with +s ld flag.

Has anyone run into this or has any pointers about this vague error
message from dlopen?

Thanks!

I assume you mean 11.22, aka 11iv1.6 yes? You do know that that
release is "EOL" and everyone really should be on 11.23, aka 11iv2
right?

Next time it would be good to include the message in the posting text
- in some newsreaders, only the first N characters of a subject are
visible.

What does "file" say about libdb2.so? Does it say it is a PA-RISC
library, or an IPF library? If you are trying to link something on an
IPF system (and your running 11.22 implies an IPF system) it has to be
an IPF object.

Hi, thanks for your response.

Yes, I am actually running 11.23.

Here is what "file" says about libdb2.so:

libdb2.so: ELF-32 shared object file - IA64

Here is what "file" says about the application binary:

DB2_UDB: PA-RISC1.1 shared executable dynamically linked -not
stripped dynamically linked

Loading IA64 library into PA-RISC main exe and vv. doesn't work.
Rebuild your DB2_UDB as IA64, or get PA-RISC libdb2.sl

Using 32-bit libdb2.sl does not work. I get this:

dlerror msg: Call to mmap() failed - TEXT libdb2.sl

Under HP-UX something can be either 32-bit or 64-bit and it can be
either Itanium (aka IPF or IA64) or PA-RISC.

All objects combined into a binary must match both architecture and
"bitness."

permissions on libdb2.sl, it should be readable and executable.
