  • Subject: alloca, yacc and lex
  • Date: Thu, 24 Aug 2000 13:39:25 -0600 (MDT)
The problem is that yacc is actually linked to bison and lex to flex.

The solution is to change the path to get yacc and lex, not bison and flex

bison generated code:

#ifndef alloca
#ifdef __GNUC__
#define alloca __builtin_alloca
#else /* not GNU C.  */
#if (!defined (__STDC__) && defined (sparc)) || defined (__sparc__) || defined (
__sparc) || defined (__sgi)
#include <alloca.h>
#else /* not sparc */
#if defined (MSDOS) && !defined (__TURBOC__)
#include <malloc.h>
#else /* not MSDOS, or __TURBOC__ */
#if defined(_AIX)
#include <malloc.h>
 #pragma alloca
#else /* not MSDOS, __TURBOC__, or _AIX */
#ifdef __hpux
#ifdef __cplusplus
extern "C" {
void *alloca (unsigned int);
};
#else /* not __cplusplus */
void *alloca ();
#endif /* not __cplusplus */
#endif /* __hpux */
#endif /* not _AIX */
#endif /* not MSDOS, or __TURBOC__ */
#endif /* not sparc.  */
#endif /* not GNU C.  */
