/usr/lib/hpux32/dld.so: Cannot dlopen load on HPUX 11.23

On HPUX 11.23 when I start my daemon I get the following error, what can be the reason ?

/usr/lib/hpux32/dld.so: Cannot dlopen load
module '/usr/lib/hpux32/libc.so.1' be
cause it contains thread specific data.

Your daemon was compiled with a diffrent set of libraries and some how they have been upgraded / changed.

Have you installed any patches recently ?.

Anyway if you can re-compile the daemon executable it should do the trick

Hi Kapil,

Thanks.
I will try to recompile.There was no patches installed. Was any patches released on HPUX 11.23.

I suggest to boot your system into single user mode.Reboot your system.
1.HPUX> hpux -is
[go to the single user mode.]
2.# bdf
you see only / and stand
3. Mount /usr on /tmp
4. cd /usr/lib/hpux32
5. /tmp/usr/bin/ls *.so

See if you see the dld,libc files. I doubt they might have got renamed or deleted.

Hi Bharat,

If after reboot in single user mode if files exist under the directory you mentioned, does that mean the files are corrupt. Please correct me if I my understanding is wrong.

Did you checked it?

[Suresh_36]

Solution.
1. Deleted /lib/libc.so.1 file.
2. Installed OS patch [PHCO_30531/PACHRDME/English] (include [PHCO_29957/PACHRDME/English] ).

this message does not mean anything is corrupt, so dont bother checking all that. this is a known limitation in dld, it cannot dynamically load any shared library that contains thread local storage. the solution is to link your program against any such libraries you may need to load dynamically. a workaround is to set the env variable LD_PRELOAD to a colon-delimited list with the full paths of all such shared libraries in proper order, in the shell where the program is invoked.

so in your case, link your program with -lc in the compile/link line (arent you doing so already?). the workaround is to set LD_PRELOAD=/usr/lib/hpux32/libc.so.1 in the shell where you start the daemon.
