"Unresolved symbols" error

Bharath K — Fri, 02 Sep 2005 01:14:38 GMT

Dear all,
I am getting the following "Unresolved symbols" error when I try to run the executable which has been built with aCC 3.60 on HP-UX 11.11.Also I have used -AA option when building my executable.libmaverick50 & libxerces-c2_1 are third party libraries which has been built on a aCC 3.13.
Can any one tell me if there is any link option or library to be included to solve this problem?

Try to export SHLIB_PATH=/usr/lib and run the executable.

And to

/home/builder/tibco/tpcl/5.2/lib

Thanks Muthu and Agarwal for your immediate response.
The shlib path has been updated to point to /usr/lib and /home/builder/tibco/tpcl/5.2/lib
and other required libraries.
I am still facing the same errors.
regards,

What happens if you run ldd against your executable?

# ldd your_exe

If your system is 64 bit then i think you have to update your

LD_LIBRARY_PATH

Hi Stephan,
On running ldd , I am able to see the list of all the libraries referred and their paths.The ldd is able to find the all the required libraries.

Thanks,
Bharath

If ldd works OK, then your SHLIB_PATH is probably setup correctly. Do you have (in /usr/lib) libstream.sl, libC.sl, libC.ansi.sl ?

Cross-Check the patches on which the third party libraries had been built.

Re: "Unresolved symbols" error

Bharath K — Fri, 02 Sep 2005 04:09:18 GMT

Hi Muthukumar,
The latest patch applied is PHSS_31221.
I think this will cover the patch PHS_22898 also.

Re: "Unresolved symbols" error

Bharath K — Fri, 02 Sep 2005 04:14:05 GMT

Hi Stephen,
The /usr/lib has all of the following libraries
libstream.sl, libC.sl, libC.ansi.sl.

Hi Vibhor Agarwal,
I will try to know on what patches the third party libraries have been built.I dont know from which library these unresolved symbols come from.

Have you used

using namespace std;

in your source code?

Re: "Unresolved symbols" error

Bharath K — Fri, 02 Sep 2005 04:36:15 GMT

Stephen,
I have'nt used the using name space std.
But the aCC 3.60 compiler automatically does that.
This warning which I got when I compiled my code suggests that:

Warning 890: "/opt/aCC3.60/opt/aCC/include_std/iostream_compat/iostream.h",
line 4 # #warning is being replaced by followed by
"using namespace std;"
