I am migrating the code written in SUN 4.3 to SUN 5.8
while linking i am getting the following errors
Code:
Undefined first referenced
symbol in file
cerr ../../../../libs/lib/libgeneral.a(string.o)
unsafe_ostream::operator<<(long) ../../../../libs/lib/libgeneral.a(string.o)
operator delete(void*) msggen.o

_ex_rethrow_q msggen.o
ld: fatal: Symbol referencing errors. No output written to msggen
*** Error code 1
I have written a sample program using the Prototypes for which it is firing out above error
#include<stdio.h>
#include<iostream.h>
int main()
{
int len=10;
char *coded = new char[len];
int *a=new int();
printf("Herllo");
cerr<<"Hello world:";
cerr << "\nString Array Out of Bounds!! index: " << ":elem"
<< " String length (0-"
<<" len" << ")\n";
delete [] coded;
delete a;
}
i could able to compile and run the program
so i am not getting any pointers to fix the issue. any pointer to fix the issue are highly appreciated.
Regards.

Assuming that this is the problem you're still seeing, have you recompiled everything with the new compiler?
It looks like the compiler can't find the C++ run-time libraries. Or it can't find the proper version...
There's probably a command-line option for the CC command to have it emit intermediate steps, so we can see what commands are actually getting run, especially the final link step.
Or, you can just run that CC link command under truss, and just truss the execve() calls:
Code:
truss -f -t\!all -texecve -vexecve -a -e -o /output/file/name CC ...
You can also post here, where you're likely to get help from someone who actually works for Oracle on the Studio compilers:

Hi all.
I have a simple question.
There's a way to install under AIX system (5.3) two different compiler version, i.e. ibm xlf fortran 11 and 12?
Seems that smitty doesn't allows user to change the default installation path; it only allows you to save the replaced files of the superseded... (1 Reply)

gsl-config - script to get version number and compiler flags of the installed GSL library
SYNOPSIS
gsl-config [--prefix] [--version] [--libs] [--libs-without-cblas] [--cflags]
DESCRIPTION
gsl-config is a tool that is used to configure to determine the compiler and linker flags that should be used to compile and link programs
that use GSL. It is also used internally to the .m4 macros for GNU autoconf that are included with GSL.
OPTIONS
gsl-config accepts the following options:
--version
Print the currently installed version of GSL on the standard output.
--libs Print the linker flags that are necessary to link a GSL program, with cblas
--libs-without-cblas
Print the linker flags that are necessary to link a GSL program, without cblas
--cflags
Print the compiler flags that are necessary to compile a GSL program.
--prefix
Show the GSL installation prefix.
