/usr/lib/dld.sl: Unresolved symbol -- (plabel) from -- a shared library

Hi

When we are trying to run the executable (PCRG_Srvr) it runs but unable perform some functionality containing the functions that we are getting while bringing up the server.

Some part of the error
-----------------------

/usr/lib/dld.sl: Unresolved symbol: IF_GetC12000Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT (plabel) from /opt/trims/prd/lib

ldd of libRGlib.sl also show the same error. So I greped for the function in my code and found the functions in another
shared libraray libTIPS_IF.sl.

nm++ libTIPS_IF.sl | grep IF_GetC12000Hoff

static___soa_IF_GetC12000Hoff_c_|1074934816|static|data |$DATA$CDTORC1$

While doing ldd of the library getting the following error but I hope this is not an error as it comes for all shared libraries.
ldd libTIPS_IF.sl
/usr/lib/dld.sl: Unresolved symbol: symbol not found: __shlinit (libTIPS_IF.sl)

I checked SHLIB_PATH also it contains the required paths where the all the libraries lies.

File out out of the binaries and servers.

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

file libRGlib.sl
libRGlib.sl: PA-RISC1.1 shared library -not stripped

file libTIPS_IF.sl
libTIPS_IF.sl: PA-RISC1.1 shared library -not stripped

Running it on a unix machie with following specification.
HP-UX uxhyd02 B.11.11 U 9000/800 172400551 unlimited-user license

compiler version

aCC: HP ANSI C++ B3910B A.03.50

But the same sorce code / binary is working on differnet machine. So as I think there is nothing wrong in the code or paths.

Can any one please suggest how to resolve the issue.

Thanks in advance

Hi,

check the patch level of this ws and one where the script is running well.
'swlist -l product|grep link'
You should use the newest patch of:
ld(1) and linker tools cumulative patch

Hi Pradeep,

aCC: HP ANSI C++ B3910B A.03.50 is old. You should try upgrading to PHSS_33944. http://www1.itrc.hp.com/service/patch/patchDetail.do?patchid=PHSS_33944&sel={hpux:11.11,}&BC=main|search|

The version of the compiler shouldn't make a difference. You should use:

odump -slexport ibTIPS_IF.sl | grep IF_GetC12000Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT

To see if the symbol is exported.

__shlinit should be found in libCsup.2.
Have you tried "ldd PCRG_Srvr"?

Hi Nyga

The required details are .

swlist -l product|grep link
Networking B.11.11 HP-UX_Lanlink_Product
PHKL_27949 1.0 shm_lock scaling; shm_open-shm_unlink audit
PHKL_28185 1.0 Tunable;vxportal;vx_maxlink;DMAPI NFS hang
SNAplus2-Link R6.11.11.100 Supports communication over SDLC, QLLC, and LAN links

Please suggest which patch should we apply ?
And will the patch resolve the issue ?
Thanks for your reply.

Hi Arunvijai
Thanks for the suggestion. But the same version of aCC is there in our other machines where the code is working fine.

Hi Dennis

As per your suggestion we tried the ldump also and the output is like

odump -slexport libTIPS_IF.sl | grep IF_GetC12000Hoff
000000013 000000003 00000 0x000f76cc Code 000000,155 00 IF_GetC12000Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT
000000032 000000013 -0001 0x40001510 Plab 000000,155 00 IF_GetC12000Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT

And libCsup.2. already included in the shared library list of our binary as it is in the chatr output of the executable.

We had tried ldd PCRG_Srvr and in that also getting the same error.

/usr/lib/dld.sl: Unresolved symbol: symbol not found: IF_GetC12000Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT (/opt/tr
ims/prd/lib/libRGlib.sl)
/usr/lib/dld.sl: Unresolved symbol: symbol not found: IF_GetS016Hoff__FP15IF_TMP_TXN_DATAPcP16SYS_ERROR_STRUCT (/opt/tr
ims/prd/lib/libRGlib.sl)
Thanks for the reply.
Any suggestions?

Thanks to all.

Hi again,

I only have the Europian link:
http://www4.itrc.hp.com/service/patch/patchDetail.do?BC=main|pdb|search|patchDetail{PHSS_22535,{hpux:11.11,}}|&patchid=PHSS_33037&sel={hpux:11.11,}
The patch is PHSS_33037.
Maybe if you change the 'www4' to 'www2' or 'www1' you come to the Asian site, else you have to search from 'patch database'.

Your executable looks for 32bit libraries, it seems to be an old exe, but I think it should run.

See also:
http://docs.hp.com/en/5966-9887/ch01s05.html

What's about the other maschine:
'But the same sorce code / binary is working on differnet machine. So as I think there is nothing wrong in the code or paths.'

Can you see any differences in patch level or OS? (HP-UX 10.20? 11.0?)

Dennis Handly — Mon, 25 Sep 2006 19:11:35 GMT

To find linker patches, you need grep -i. The latest 11.11 linker patch is PHSS_33037.

>We had tried ldd PCRG_Srvr and in that also getting the same error.

Try chatr PCRG_Srvr instead. Does it showlibTIPS_IF.sl?
