octave.2.0.5.NeXT
Mar 1997


Here are some things you need to do to get octave to compile for Nextstep.


1.  If using g77 (ie, g77-0.5.20 and gcc-2.7.2.2.f.2), need to configure with:
    configure --with-g77 (so... whenever I say run configure, you need
    to include --with-g77.


2.  fix configure
	- modify config.cache so termios.h,unistd.h,utsname.h are no
          (they are posix only headers, and shouldn't be used).
	- re-run configure: configure --with-g77

3.  fix Makeconf
	- modify CXXLIBS to be: -lm
	- modify FLIBS to be: -lf2c

4.  strdup

You need an implementation of the C functio strdup for info and makedoc.
Either:
#define strdup(x)	NXCopyStringBuffer(x)
In the files that refer to strdup, or create a file named: strdup.c
#include <stdlib.h>

#if defined(NeXT)
/**
 * strdup() - Duplicate a string.
 * 
 * Returns a pointer to a new string which is a duplicate of the
 * string to which s1 points.  The space for the new string is
 * obtained using the calloc() function (see calloc(3C)).
 *
 * Parameters: [1] inStr - String to duplicate.
 * Returns: Pointer to duplicated string; or NULL if an error occurred.
 **/
char *strdup(const char *inStr)
{   char *outStr;
    if (NULL == inStr)
    { outStr = NULL; }
    else
    { outStr = calloc((strlen(inStr) + 1), sizeof(char));
      if (NULL != outStr)
        { strcpy(outStr, inStr); }
    }
    return outStr;
}
#endif /* NeXT */

Do a 'gcc -O -c strdup.c' and then include the strdup.o object file in the
makefile objects for info and makedoc.


5.  hypot redefinition:
kpathsea/c-std.h:97: conflicting types for `hypot'
Remove reference (comment it out or remove it)

6.  liboctave/Array.h (and liboctave/Array2.h) and anywhere else that complains 
about index, stick these #if's right before the reference to index.

#ifdef index
#undef index
#endif
  Array<T> index (idx_vector& i) const;


7.  fix signal.h 

                       i386
/usr/local/lib/gcc-lib/m68k-next-nextstep3/2.7.2.2.f.2/include/bsd/sys/
so that it reads:

NOTE: the old defs of the signals are not liked by g++:

--------
#ifdef __STRICT_BSD__
        #define BADSIG          (int (*)(int))-1
        #define SIG_DFL         (int (*)(int))0
        #define SIG_IGN         (int (*)(int))1

        #ifdef KERNEL
                #define SIG_CATCH       (int (*)(int))2
                #define SIG_HOLD        (int (*)(int))3
        #endif

#else /* __STRICT_BSD__ */

        #ifdef _NEXT_SOURCE
                #define BADSIG          (void (*)(int))-1
        #endif /* _NEXT_SOURCE */

        #if defined(_NEXT_SOURCE) || defined(_POSIX_SOURCE)
                #define SIG_DFL         (void (*)(int))0
                #define SIG_IGN         (void (*)(int))1
...
