make fails with cannot find library "DtHelp"

Jo Davis — Fri, 19 Mar 2010 14:39:34 GMT

Have been running the same make file for years and it just stopped working with the error:
/usr/ccs/bin/ld: Can't find library: "DtHelp"
*** Error exit code 1

make file has the /usr/dt/lib file specified as follows:
MOTIF_LIBPATH = -DCOSE -DCDE10 -L/usr/dt/lib
LIBPATH = $(X_LIBPATH) $(MOTIF_LIBPATH) -L$(UX_LIBPATH) $(GPS_LIBPATH) \
-L$(LIBHOME32)
LIBS = -lux $(X_LIBS) -lPW -ldld -lgps -ltermcap \
-lm /usr/lib/libm.1 -lDtHelp -lDtSvc -lDtWidget -lXext -ll \
-lc -lXp $(STATICPROLDLIBS)

Library environment variables are setup as follows:
SHLIB_PATH=/src/oracle/product/9.2.0/lib32
LD_LIBRARY_PATH=/usr/lib:/src/oracle/product/9.2.0/lib:/opt/uimx3.0/lib
LIBRARY_PATH=/usr/lib:/src/oracle/product/9.2.0/lib:/opt/uimx3.0/lib

I loaded patches back in february and the last time that this was compiled was in december. I backed out of the linker patch as that was the only thing I could think of that would affect this but that didn't make any difference so I know it wasn't that patch that caused this issue. Any ideas?

So, where is (was?) "libDtHelp.*"?

Often interesting:

uname -a

It is in /usr/dt/lib

Still true. Around here, for example,
"man ld" (always interesting) mentions
"LPATH", but not "LIBPATH", so I don't know
what you're doing with that thing.

With my weak psychic powers, I can't see your
actual link command any better than I can
divine your OS and hardware architecture.

Also:

dyi # find /usr/dt -name 'libDtHelp*'
/usr/dt/lib/libDtHelp.1
/usr/dt/lib/libDtHelp.2
/usr/dt/lib/libDtHelp.3
/usr/dt/lib/pa20_64/libDtHelp.3
/usr/dt/lib/hpux32/libDtHelp.so.1
/usr/dt/lib/hpux32/libDtHelp.so
/usr/dt/lib/hpux64/libDtHelp.so.1
/usr/dt/lib/hpux64/libDtHelp.so

It is a pa system RP3410 running HP UX 11.23
If you prefer the find command, it is as follows:
splash:/src/oracle/product/9.2.0 # find /usr/dt -name 'libDtHelp*'
/usr/dt/lib/libDtHelp.1
/usr/dt/lib/libDtHelp.2
/usr/dt/lib/libDtHelp.3
/usr/dt/lib/hpux32/libDtHelp.so.1
I have attached the entire make file if that helps.

(Note: make isn't failing, ld is.)

>Library environment variables are setup as follows: SHLIB_PATH= LD_LIBRARY_PATH= LIBRARY_PATH=

These are useless for linking.

>libDtHelp.1 libDtHelp.2 libDtHelp.3

And these are useless as well. You are missing a symlink from libDtHelp.sl to libDtHelp.3.
# ln -s libDtHelp.3 /usr/dt/lib/libDtHelp.sl

I lack 11.23, but on an 11.11 (PA-RISC)
