make: *** [Zend/zend.lo] Error 1
I checked the problem lines in zend.c:
#if (defined(__GNUC__) && __GNUC__ >= 3 && !defined(__INTEL_COMPILER) &&
!defined(DARWIN) && !defined(__hpux) && !defined(_AIX) &&
!defined(__osf__))
void zend_error_noreturn(int type, const char *format, ...)
__attribute__ ((alias("zend_error"),noreturn));
#elif defined(ZEND_WIN32) || defined(DARWIN)
ZEND_API void zend_error(int type, const char *format, ...) /* {{{ */
{
va_list va;
va_start(va, format);
zend_error_va_list(type, format, va);
va_end(va);
}
ZEND_API ZEND_NORETURN void zend_error_noreturn(int type, const char
*format, ...)
{
va_list va;
va_start(va, format);
zend_error_va_list(type, format, va);
va_end(va);
}
/* }}} */
#endif
As defined in zend.h:
#ifdef HAVE_NORETURN
# if defined(ZEND_WIN32)
ZEND_API ZEND_NORETURN void zend_error_noreturn(int type, const char
*format, ...);
# else
void zend_error_noreturn(int type, const char *format, ...)
ZEND_NORETURN;
# endif
#else
# define zend_error_noreturn zend_error
#endif
zend_error_noreturn is defined as zend_error, so
ZEND_API ZEND_NORETURN void zend_error_noreturn(int type, const char
*format, ...)
is expanded to
ZEND_API ZEND_NORETURN void zend_error(int type, const char *format,
...)
which is already defined.
Expected result:
----------------
Compilation succeeds.
Actual result:
--------------
Compilation failed.
