Hi All

when I am compiling the cxx file on the system with compiler version (CC: Sun C++ 5.9 SunOS_sparc 2007/05/03) , I am facing the following error:-

/opt/SUNWspro/bin/CC -dy -misalign -xcode=abs64 -xarch=v9 -D__EXTENSIONS__ -Dsun4_R5=1 -I. -Isun4_R5_v -I/home/as185259/ash_iadraid/ash_get_10/IA/PORT/include -I/home/as185259/ash_iadraid/ash_get_10/IA/WV/WV5.3.6-ncr0302/build/include/sun4_R5_v -I/app/oracle/product/10.2.0/client_1/sqllib/public -I/app/oracle/product/10.2.0/client_1/precomp/public -I/opt/informix/include -DSVR4 -O -g p -pta -c MContext.cxx -o sun4_R5_v/MContext.o || \

4 Error(s) detected.



The same file with the same compilation command is getting compiled with compiler version CC: Sun WorkShop 6 update 2 C+ 5.3 2001/05/15 .
Can anyone suggest what should be the resolution:-

The code for the ssmalloc.h file is as under:-

#ifndef SSMALLOC_H
#define _SSMALLOC_H

#include <stddef.h>

#if defined(__sparcv9)
namespace ssmalloc {
#endif
#if defined(__cplusplus)
extern "C" {
#endif

/
The type for the malloc routine depends on
the compiler and library that you are using.
/
#if defined(hpux) || defined(sun4_R5) || defined(__GNUC_) || defined(_OS2_)
typedef void MALLOC_PTR;
#else
typedef char *MALLOC_PTR;
#endif

#if defined(_GNUG_)
typedef size_t MALLOC_SIZE;
#else
typedef unsigned MALLOC_SIZE;
#endif

#if defined(sun4) && ! defined(_GNUG_)
# define FREE_RETURNS int
# define FREE_RETURN return 0
#else
# define FREE_RETURNS void
# define FREE_RETURN return
#endif


//
//
// User-callable routines.
//
//
// Note: memalign and valloc are broken in that they do not aling
// memory on documented boundaries, and thus do not behave as described
// on the "malloc" manual page. They simply call malloc.
//
//
MALLOC_PTR malloc (MALLOC_SIZE size);
FREE_RETURNS free (MALLOC_PTR data);
MALLOC_PTR realloc (MALLOC_PTR data, MALLOC_SIZE size);
MALLOC_PTR calloc (size_t nelem, size_t elsz);
MALLOC_PTR valloc (unsigned size);
MALLOC_PTR memalign (unsigned alignment, unsigned size);

//
// This memory allocator supports memory allocation inside signal
// handlers. For correct operation, the following functions must be
// called upon entering and exiting signal handlers that allocate
// memory.
//

void ssmalloc_enter_signal_level();
void ssmalloc_exit_signal_level();

//
// Set this variable to not 0 (possibly in the debugger) if you want
// to get malloc to check memory data structures very carefully as it
// goes. This may be handy if you are trying to detect a memory
// trasher.
//
// It also causes ssmalloc to abort the program instead of returning
// zero if memory runs out.
//
extern int check_memory_very_carefully;

#if defined(__cplusplus)
}
#endif

#if defined(__sparcv9)
} // namespace ssmalloc {
#endif
#endif / _SSMALLOC_H */

Welcome to LQ !

Your ssmalloc.h file has 83 lines while the errors reported starts at line 97, please double check this is the right file.

Please use code tags to enclose code and similar samples.

The comments which were present at the start of the file have been removed , and the error messages are referring to the lines where these functions are declared:- malloc, realloc , valloc and memalign
