ELF format shared library?
HP Unix v 11. I have a shared library that I think I need to make ELF compatible because when I link it with my main pgm and a vendor's library I get this error:
ld: Mismatched ABI (not an ELF file)
I can't find any info on how solve this. Is this a linkedit option or something to my c program I need to modify or a cc option???
Thanks. Matt

You say HPUX 11, but running on what?

There are basically five different runtimes, as follows....

CPU width Packaging
PA-RISC1.1, 32 bit mode, SOM
PA-RISC2.0, 32 bit mode, SOM
PA-RISC2.0, 64 bit mode, ELF
Itanium-2, 32 bit mode, ELF
Itanium-2, 64 bit mode, ELF

The immediate giveaway is if the library is of the form

"lib*.so[.major[.minor]]"

then it's ELF, if it's

"lib*.sl" or "lib*.major[.minor]"

then it's PA-RISC, if it's 32 bit then it's SOM.

You can only link like with like.

Thanks, Now how to create an ELF shared library?
Porter:
Thanks for the the info. I can't answer the hardware question, but I'll find out if it makes a difference for my problem.
I have to link in a vendor's library, which is ELF format, with one of our own shared library which is not. Understand all libs then have to be ELF. So, how do I get my shared library to be in ELF format?
Thanks, Matt

Post the results of

Code:
uname -a

Which compiler are you using?

This is a PA-RISC platform and should be using SOM for 32 bit or ELF for 64 bit. Are you building a 32bit or 64 bit application?

What is the library compiled for?

Do "elfdump" on the library to determine the format of it and post the results.
