Hi All,
not sure if this is the right place to ask compile questions
for user apps ...
i am using a non Sun studio compiler, and it is complaining
that "long long" is not supported (i understand that the type
is standard since 1999).
after generating a .i file, i noticed that the following sections
were bring included.
/usr/include/sys/int_types.h:
83 #ifdef _LP64
84 #define _INT64_TYPE
85 typedef long int64_t;
86 #else /* _ILP32 */
87 #if defined(_LONGLONG_TYPE)
88 #define _INT64_TYPE
89 typedef long long int64_t;
90 #endif
91 #endif
i do not know how my compiler is passing
_LONGLONG_TYPE to the preprocessor.
as a test, i tried the sun studio compiler
from the sxde distribution. i tried to turn off
the macro by using -U and also:
cc -# -Wp,-U,_LONGLONG_TYPE -P tt.c
what i found is that both methods do not
turn off the _LONGLONG_TYPE symbol.
(even though the cc manpages said they
should even turn off symbols defined by
the compiler driver)
also, the verbose output does not indicate
where the -D_LONGLONG_TYPE is being
passed:
]# cc -# -P tt.c
