Hello,

I am working on migration of code from 4.2 to 5.8

I can complie a snippet with CC 5.8


Code:
#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";
int len1=strlen("idjfhdjfjtxt") + 1;
printf("%d\n",len1);
delete [] coded;
delete a;
}

Code:
CC sample.C
compiled well and good and i could see the out put when i run

Code:
CC --compat=4 sample.C
"Ccode.C", line 13: Error: The function "strlen" must have a prototype.
1 Error(s) detected.

How can i resolve this, as i am migrating my entire code during linking i am getting many symbol referencing errors as mentioned in previoues post


Thanks in advance,
Revathi R.

cc(1B)						     SunOS/BSD Compatibility Package Commands						    cc(1B)

NAME

       cc - C compiler

SYNOPSIS

       /usr/ucb/cc [options]

DESCRIPTION

       /usr/ucb/cc  is the interface to the BSD Compatibility Package C compiler. It is a script that looks for the link /usr/ccs/bin/ucbcc to the
       C compiler. The /usr/ccs/bin/ucbcc link is available only with the SPROcc package, whose default location is /opt/SUNWspro. The /usr/ucb/cc
       interface  is  identical  to  /usr/ccs/bin/ucbcc, except that BSD headers are used and BSD  libraries are linked before base libraries. The
       /opt/SUNWspro/man/man1/acc.1 man page is available only with the SPROcc package.

OPTIONS

       The /usr/ucb/cc interface accepts the same options as /usr/ccs/bin/ucbcc, with the following exceptions:

       -Idir	    Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The directo-
		    ries  for  multiple  -I options are searched in the order specified. The preprocessor first searches for #include files in the
		    directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and finally, in
		    /usr/include.

       -Ldir	    Add  dir to the list of directories searched for libraries by /usr/ccs/bin/ucbcc. This option is passed to /usr/ccs/bin/ld and
		    /usr/lib. Directories specified with this option are searched before /usr/ucblib and /usr/lib.

       -Y P, dir    Change the default directory used for finding libraries.

EXIT STATUS

       The following exit values are returned:

       0     Successful compilation or link edit.

       >0    An error occurred.

FILES

       /usr/ccs/bin/ld	     link editor

       /usr/lib/libc	     C library

       /usr/ucbinclude	     BSD Compatibility directory for header files

       /usr/ucblib	     BSD Compatibility directory for libraries

       /usr/ucblib/libucb    BSD Compatibility C library

       /usr/lib/libsocket    library containing socket routines

       /usr/lib/libnsl	     library containing network functions

       /usr/lib/libelf	     library containing routines to process ELF object files

       /usr/lib/libaio	     library containing asynchronous I/O routines
