Re: [ns] Installation problem part deux (snprintf)

["Neeraj Poojary" <legolas_3@hotmail.com>]

nader,
  yes, i did type ./configure. however on closer inspection i realized that 
configure was bailing out prematurely because my earlier installation of 
2.1b5 was incorrect! so that problem is resolved. but then i had a problem 
installing on Sun...

  installing ns-allinone-2.1b6 on a Sun m/c (SunOS 5.7), 'make' in the 
ns-2.1b6 directory complained about 'snprintf' being redeclared differently 
in config.h. the declaration in the system /usr/include/stdio.h file is:
    extern int snprintf(char *, size_t, const char *, ...);

so in config.h i changed the second parameter from int to size_t as follows 
:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// Declare our implementation of snprintf() so that ns etc. can use it.
#ifndef HAVE_SNPRINTF
#if defined(__cplusplus)
extern "C" {
#endif
/*      extern int snprintf(char *buf, int size, const char *fmt, ...); */
        extern int snprintf(char *buf, size_t size, const char *fmt, ...);
#if defined(__cplusplus)
}
#endif
#endif
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

although the installation proceeded smoothly after i edited config.h,
i'm thinking the 'configure' step should have ensured that HAVE_SNPRINTF is 
#defined when my system has it?
  i didn't see this problem reported in the 'installation problems' webpage 
and yet i don't think it could be a peculiarity of my Sun
workstation.

thanks,
neeraj
