[GRASS5] Error in trying to compile for SGI

[Justin Hickey]

Hello all

I am trying to compile a set of binaries for SGI and have found the following
error:

#################################################################
/usr/people/jhickey/grassCVS/grass/src/mapdev/v.rmdup/cmd
  mkdir OBJ.mips-sgi-irix6.5
  make -f OBJ.mips-sgi-irix6.5/make.rules

"rmdup.c", line 194: error(1565): struct "__file_s" has no field "_shortbuf"
      while (match == 0 && Closet->dig_fp->_shortbuf[1])  /* try to upgrade in
5/2000 */

The actual code snippet is as follows:

/* commented following "while line" 5/2000:
 *   dig_fp->_cnt was once defined in _IO_FILE_ /usr/include/libio.h
 *   int _cnt;    "number of characters in the buffer"
 *
 * -> but today?
 */
 /*     while (match == 0 && Closet->dig_fp->_cnt) */
#ifndef __CYGWIN__
    while (match == 0 && Closet->dig_fp->_shortbuf[1])  /* try to upgrade in
5/2000 */
#else
    while (match == 0 && Closet->dig_fp->_bf._size)
#endif

The comment says that dig_fp->_cnt is no longer defined. That may be true for
Linux, but not for Irix. It is still defined and worse, _shortbuf is not
defined.

The appropriate FILE struct on Irix is as follows

typedef struct	/* needs to be binary-compatible with old versions */
#if (_SGIAPI && _NO_ANSIMODE) || defined(_LANGUAGE_C_PLUS_PLUS)
/*
 * The __file_s struct tag is for backwards compat ONLY - it shouldn't be
 * used in any new headers. We would have liked to not use it in C++ since
 * it will change the name mangling of FILE *, but since it has already
 * gone out that way, we must stick to it. The safest thing is to *always*
 * define it for C++ (since a function that takes a FILE * as an argument
 * will have this tag in its mangled name).
 */
__file_s
#endif
{
#if (_MIPS_SZLONG == 32)
	int		_cnt;	/* number of available characters in buffer */
#endif
#if (_MIPS_SZLONG == 64)
	long		_cnt;	/* number of available characters in buffer */
#endif
	unsigned char	*_ptr;	/* next character from/to here in buffer */
	unsigned char	*_base;	/* the buffer */
#if _MIPS_SIM == _ABI64
	unsigned char	_reserved[2]; /* MIPS ABI */
	unsigned short	_flag;	/* the state of the stream */
	unsigned int	_file;	/* UNIX System file descriptor */
#elif _MIPS_SIM == _ABIN32
	unsigned char	_flag;	/* the state of the stream */
	unsigned char	_o_file;	/* not used */
	unsigned short	_file;	/* UNIX System file descriptor */
#else	/* _MIPS_SIM == _ABIO32 */
	unsigned char	_flag;	/* the state of the stream */
	unsigned char	_file;	/* UNIX System file descriptor */
#endif
} FILE;


Anyone have any suggestions how to fix this? I have no idea at all.
