Expect problem...

piyush mathiya — Fri, 03 Jul 2009 21:37:54 GMT

Hi Gurus,
I am facing problem while using expect. I checked so many threads similar to my problem, but not working.

I installed, expect-5.43-ia64-11.23.depot & tcltk-8.5.7-ia64-11.23.depot successfully.

Also configure the variable "LD_LIBRARY_PATH"

Softlink also created in /usr/local/lib.
ln -s libtcl8.4.sl libtcl.sl

Still not working, getting below error.
# /usr/local/bin/expect
/usr/lib/hpux32/dld.so: Unsatisfied code symbol 'Tcl_Release' in load module '/usr/local/lib/hpux32/libexpect.so'.
/usr/lib/hpux32/dld.so: Unsatisfied code symbol 'Tcl_ErrnoMsg' in load module '/usr/local/lib/hpux32/libexpect.so'.
/usr/lib/hpux32/dld.so: Unsatisfied code symbol 'Tcl_NotifyChannel' in load module '/usr/local/lib/hpux32/libexpect.so'.

Your suggestions will be highly appreciated...!

Thanks & Regards,

Hi Piyush,

Check for this patch:
PHSS_39821 : s700_800 11.23 linker + fdp cumulative patch

This has libraries like /usr/lib/hpux32/dld.so
May be this can help....just a guess !

Regds,
R.K.

/usr/lib/hpux32/dld.so is the one who is
complaining about the missing libraries.
It's not the thing which is missing.

And if I were psychic, so I might know what
you meant by "configure the variable", then
I might know if you did it right. But I'm
not, so I don't. As usual, showing actual
commands can be more helpful than vague
descriptions.

Whatever the problem is, it keeps happening over and over. (I would say this isn't how to design software. ;-)

About the only way this can fail is that there are two versions of the same shlib and either the wrong version is installed or LD_LIBRARY_PATH is pointing to the wrong one.

From the last one, it appears that there is an evil one in: /usr/obam/lib/

/usr/lib/hpux32/dld.so found that the module
'/usr/local/lib/hpux32/libexpect.so' refered these symbols, but it couldn't find the C header file which defined those symbols, it's clear that one file of the tcltk defined these symbols, so you should find out the file which defined those symbols and point the var "LD_LIBARAR_PATH" to the directory where the file exists.
hope to be helpful...

Headers declare variables, objects or load modules define them.

>so you should find out the file which defined those symbols and point the var "LD_LIBARARY_PATH" to the directory

ldd(1) can be used to show which shlibs are being used. It shouldn't be in /usr/obam/.
