Unsatisified symbols

[Ed Hon]

I ran a vendor's script on HP-UX 11.0 to relink his software. Here is an excerpt of what I got. What is it telling me?

/usr/ccs/bin/ld: Unsatisfied symbols:
cma_socket (code)
cma_send (code)
cma_sendto (code)
pthread_create (code)
cma_connect (code)
cma_accept (code)
cma_open (code)

Thanks,

Ed

did you pass -lcma and/or -ldce? Both also contain pthread_create

Enjoy, have FUN! H.Merijn

You are above me on this one. What are -lcma and -ldce?

[A. Clay Stephenson]

The -lcma (et al) is a shorthand for the linker to use libcma.a (or .so) found in the default library location(s) -- typically /usr/lib.

You need to find the line in the makefile or script that invokes the linker (ld) or it may be a line that links several .o's using cc and simply add -lcma to that line.

If you post your linking script or makefile, it should be easy to tell you where to put it.

[H.Merijn Brand (procura]

options to ld (the loader that links all objects together), the process that issues above message

# ld -o runnable -Llibrary/path -llib -llib2 ...

Do you actually *have* /usr/lib/libcma.sl and/or /usr/lib/libdce.sl ?

Enjoy, have FUN! H.Merijn

Here's what's in the vendor supplied script. The assumption is that the current working directory is the vendor's lib subdirectory.

[ -s syslibs ] && . ./syslibs

XLIBS=""
#
# Uncomment on HP/UX 10
#
#XLIBS=-lcl

for i in dlc83d.o
do
proexe=`echo $i | sed -e 's/dlc/pro/' -e 's/\.o//'`_sv
echo "-- $proexe"
cc -s -o $proexe pro8_sv.o $i $XLIBS $SYSLIBS || continue

[ -x /usr/bin/mcs ] && /usr/bin/mcs -d $proexe
mv $proexe ../bin
ls -l ../bin/$proexe
done

[Mike Stroyan]

Those cma_* entry points are very uncommon for code built on 11.00. They are more common for code built on 10.20. You can't relink 10.20 code on an 11.00 system. It is not supported and often fails to work.

You could check the release notes or check with the vendor to see if there is an 11.00 version of the software.

It is often possible to see what compiler was used to build libraries and .o files.
/usr/ccs/bin/odump -compunit some.o
will report details about how some.o was built.
That may include the compiler version such as
HP92453-01 ; W.11.01.
or
HP92453-03; UX.10.20.02 (DAVIS)

It looks like I don't have odump:

# ll *.o
-rw-rw-r-- 1 root sys 2310648 Sep 3 09:22 dlc83d.o
-rw-r--r-- 1 root sys 705464 Mar 7 2001 pro8_sv.o
-rw-r--r-- 1 root sys 470436 Jul 31 2002 pro9_sv.o
# /usr/ccs/bin/odump -compunit pro8_sv.o
sh: /usr/ccs/bin/odump: not found.

[Adam J Markiewicz]

Check:

XLIB=-lcma

Could work.

Good luck
Adam

[Ed Hon]

Setting XLIB=-lcma gets me down to one unsatisfied symbol:

/usr/ccs/bin/ld: Unsatisfied symbols:
U_STACK_TRACE (code)

[Mike Stroyan]

You can get odump as part of patch PHSS_28434.

[ranganath ramachandra · Accepted solution]

U_STACK_TRACE is in libcl. so you need XLIB="-lcma -lcl"

PHSS_28434 has problems. PHSS_26559 should do.
