ld: Can't find library for -lclntsh

[dictum9]

11.31. Using standard cc compiler.

how do I correctly link the library?   It is apparently not on the system, where do I install it from?

When I try to compile some C code, I get this, any idea what it means? I am on 11.31.  Using native CC compiler.


        cc -o /var/tmp/mup mupp.o -L/lib/hpux64 -L/lib/ -lclntsh `cat /lib/ldflags`   `cat /lib/sysliblist`  -lelf -lm   -lrt
ld: Can't find library for -lclntsh
Fatal error.

   With my weak psychic powers, I don't really know.  Have you tried
asking the people who supplied your (invisible) "some C code"?  Who told
you to specify "-lclntsh"?  I know nothing, but a Web search for
"libclntsh" suggested to me that Oracle might be involved.

>cc ... -L/lib/hpux64 -L/lib/ -lclntsh `cat /lib/ldflags` `cat /lib/sysliblist` -lelf -lm  -lrt

Is this a 64 bit Integrity app?

These paths don't really exist: -L/lib/hpux64 -L/lib/

Remove them and take the defaults.

Also, what does this show?  cat /lib/sysliblist

Ask Steven asked, where to you have your Oracle shlibs?

The correct path for 64 bit is /usr/lib/hpux64.  But as I said, leave the defaults off.

># cat /lib/sysliblist

There is nothing here (-L) that points to the Oracle lib directory.

Now I get this, when I run the make command.

I have ncurses 5.9 installed on the system, how do I make sure the compiler recognizes them? Seems the compiler is not finding the ncurses libraries. 

I updated these varables to reflect the correct path:

echo $SHLIB_PATH
/oracle/app/product/fmw11g/forms/lib:/usr/local/lib/hpux32/:/usr/local/lib/hpux32/:/usr/lib/hpux64

You need to pass -L and -l to the driver to pick up these shlibs.

For aC++ you can look at:

SHLIB_PATH is NOT used during linking, only during execution.

It does compile the program. But when I run it, I get this. It looks like it cannot find the curses package, which I do have installed on the system.

how do I do that? and what is the path for the curses library to use, which is what it's missing.
