Dear Sirs,

what are the different kinds of shared objects (dynamic linked library) on hpux ?

How these objects are being created ?

Thanks,
Shiv

Hi Shiv,

You mean, what are the available types ?

In PA, it is always with *.sl

PA-RISC1.1 shared library
PA-RISC2.0 shared library
ELF-64 shared object file - PA-RISC 2.0 (LP64)

Shared object file will be differed based on platform as like object (executable) file. View with file command as,

file

or chatr

To create shared library use compiler cc or gcc.

Hi,

These are based on the CPU architecture version. For ex.


PA-RISC1.1 shared library
PA-RISC2.0 shared library
ELF-64 shared object file -PA-RISC2.0(LP64)

One will never require to create these. These are part of OS and are installed alongwith installation/patching.

HTH,
Devender

Hi Shiv,

In IPF or IA-64, it is with .so extension, and shared libs are in /usr/lib/hpux32 and /usr/lib/hpux64 respectively,

ELF-32 shared object file - IA64
ELF-64 shared object file - IA64

Hi Shiv,

To answer "How these objects are being created ?"

"ld" Link editor is used.

$ cc -Aa -c +z test.c test1.c

$ ld -b -o libtest.sl test.o test1.o

You can refer this doc for more information,
