Libraries linked to an executable

Anand_30 — Fri, 12 Sep 2003 14:42:15 GMT

Is there any way to find out what are the libraries linked to an executable. i am working in HP-UX-10.20.

use the chatr command

example :
chatr ls
ls:
shared executable
shared library dynamic path search:
SHLIB_PATH disabled second
embedded path disabled first Not Defined
shared library list:
dynamic /usr/lib/libcurses.1
dynamic /usr/lib/libc.2
shared library binding:
deferred
global hash table disabled
plabel caching disabled
shared vtable support disabled
static branch prediction disabled
executable from stack: D (default)
kernel assisted branch prediction enabled
lazy swap allocation disabled
text segment locking disabled
data segment locking disabled
third quadrant private data space disabled
fourth quadrant private data space disabled
data page size: D (default)
instruction page size: D (default)

Rgds,

Well in HP-UX11.00 you use

chatr

e.g.

chatr oracle
oracle:
shared executable
shared library dynamic path search:
SHLIB_PATH enabled first
embedded path disabled second Not Defined
shared library list:
dynamic /all/oracle/product/8.1.7/lib/libjox8.sl
dynamic /all/oracle/product/8.1.7/lib/libobk.sl
dynamic /usr/lib/librt.2
dynamic /usr/lib/libpthread.1
dynamic /usr/lib/libnss_dns.1
dynamic /usr/lib/libdld.2
dynamic /usr/lib/libm.2
dynamic /usr/lib/libc.2
shared library binding:
deferred
global hash table disabled
plabel caching disabled
global hash array size:1103
global hash array nbuckets:3
shared vtable support disabled
static branch prediction enabled
executable from stack: D (default)
kernel assisted branch prediction enabled
lazy swap allocation disabled
text segment locking disabled
data segment locking disabled
third quadrant private data space disabled
fourth quadrant private data space disabled
data page size: D (default)
instruction page size: D (default)

I don't remember it being any different in 10.20...

As far as I know the ldd do the same trick:
# ldd /bin/ls
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libcurses.1 => /usr/lib/libcurses.1
The output is different (much poorer in ldd case) but you have the information regarding the dinamic libraries.

Hi,

here is document, where can you find some detail information about software development on HP-UX.

Hello Radim,

You seem to have forgotten the attachment/pointer?

Perhaps you wanted to poitn us to:

http://docs.hp.com/hpux/onlinedocs/dev/B2355-90730/B2355-90730.html#RN.CVT.NN134

this is the chapter "Viewing library dependencies with ldd(1)" in "HP-UX Linker and Libraries User's Guide".

hth,
Hein.

no ldd on 10.20, i guess. while chatr prints out the recorded list of libraries needed by the application, "odump -sllibloadlist" should give you a list of the paths where the libraries are actually getting loaded from.

i'm not sure if this is implemented on 10.20 :
_HP_DLDOPTS="-ldd" a.out

(run a.out with _HP_DLDOPTS set to "-ldd").
