*** 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:

freealut-config(1)					      General Commands Manual						freealut-config(1)

NAME
freealut-config - script to get information about the installed version of freealut SYNOPSIS
freealut-config [ --prefix= DIR] [ --exec-prefix= DIR] [ --version ] [ --libs ] [ --cflags ] DESCRIPTION
freealut-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link progams, libraries, and plugins that use freealut. The use of freealut-config is deprecated. The more generic tool pkg-config should be used instead. OPTIONS
--cflags Print the compiler flags that are necessary to compile a program or library that uses freealut. --exec-prefix=DIR If specified, use DIR instead of the installation exec prefix that freealut was build with when computing the output for the --cflags and --libs options. This option must be specified before any of the --cflags and --libs options. --libs Print the linker flags that are necessary to link a program or library that uses freealut. --prefix=DIR If specified, use PREFIX instead of the installation prefix that freealut was built with when computing the output for the --cflags and --libs options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be specified before any of the --cflags and --libs options. --version Prints the currently installed version of freealut on standard output. EXAMPLES
gcc -o main.o $(freealut-config --cflags) -c main.c is how you might use freealut-config to compile a C source file for an executable program. gcc -o my_app $(freealut-config --libs) main.o util.o is how you might use freealut-config to link compiled objects into an executable program. SEE ALSO
pkg-config(1) This manual page was written for sdl-config by Branden Robinson, originally for Progeny Linux Systems, Inc., and the Debian Project. It was adapted to freealut by Sam Hocevar. freealut 2003-11-22 freealut-config(1)
