Linker errors

[Sanjib Talukdar]

All,
I am trying to port our application from HP UX B.10.20 to HP UX B.11.0. I am getting the following error from one of our third party libraries while building the application:

/usr/ccs/bin/ld: Unsatisfied symbols:
xdr_float (first referenced in /prod/ssi/ssi-3.18/uia/hasde/lib/libhasde.a(msg_xdr.o)) (code)

xdr_char (first referenced in /prod/ssi/ssi-3.18/uia/hasde/lib/libhasde.a(msg_xdr.o)) (code)

All are related to the rpc functions and on HP UX 10.20 they were getting linked from libc.a in /usr/lib directory. I am led to believe so from the following output:

$> odump -sym libc.a | grep -e xdr_float -e xdr_int -e xdr_vector -e xdr_string
-e xdr_pointer -e xdrstdio_create -e xdr_bytes -e xdr_u_char -e xdr_long -e xdr_
u_short -e xdr_char

I checked the libc.a file on HP UX 11.0 and the above functions are not part of this library.

Can anyone please tell me which library on HP UX 11.0 will have the above rpc related functions?

Thank You.
Sanjib.

Those symbols are defined in /usr/lib/libnsl.sl.

[Manish Srivastava]

Hi,

If you are linking to the archive version then /usr/lib/libnsl.a is the right library.

Mike, Manish,
Thank you for your replies. I managed to identify the library, but I would further like to clarify if there are any backward compatibility issues or not.

[Mike Stroyan]

You may also need to link with libxti.sl.
This transition impact is discussed in http://devrsrc1.external.hp.com/STK/impacts/i555.html

You could look at the "Software Transition Kit" site at http://devrsrc1.external.hp.com/STK/
There are scanner tools an lists of impacts from transitions. The 10.20 to 11.00 transition is a little bit old by now.

[Manish Srivastava]

hi,

genrally lib*.1 is for compatiblity and lib*.2 is for the latest release. You can try linking to lib*.1
