Hi folks,
I'm trying to compile kdebase-3.5.4 against the headers installed via
'make headers_install' from linux-2.6.18. Unfortunately, I get this error:
error: '__s64' does not name a type
/usr/include/linux/joystick.h:132: error: '__s64' does not name a type
Now, obviously that's not good, but I don't think it's kdebase's fault
(linux/joystick.h is installed afterall, so they're using a permitted API).
The problem seems to be that linux/joystick.h is #including asm/types.h
which only typedefs __s64 if __GNUC__ is defined and __STRICT_ANSI__
isn't defined:
#if defined(__GNUC__) && !defined(__STRICT_ANSI__)
typedef __signed__ long long __s64;
typedef unsigned long long __u64;
#endif
I can only presume, because of the error above, that those conditions
aren't being met, but a cursory glance of the logfile doesn't appear to
help me ascertain which one of them is triggering the problem above.
Any ideas, folks?
Matt.
Matt,
as a starter, something crude like this for a separate program,
e.g. types.c.
#include <stdlib.h>
#include <stdio.h>
#include <linux/joystick.h>
main() {
#if defined(__GNUC__)
printf("__GNUC__ is defined\n");
#else
printf("__GNUC__ is NOT defined\n");
#endif
#if defined(__STRICT_ANSI__)
printf("__STRICT_ANSI__ is defined\n");
#else
printf("__STRICT_ANSI__ is NOT defined\n");
#endif
}
If I compile and run this on pure64 using the CLFS headers, I get
[EMAIL PROTECTED] ~ $./types
__GNUC__ is defined
__STRICT_ANSI__ is NOT defined
Likewise. I think I've figured it out. Try compiling that with:
# gcc -ansi -o types types.c
and you'll get:
In file included from types.c:3:
/usr/include/linux/joystick.h:131: error: expected
specifier-qualifier-list before ‘__s64’
Taking a look at /usr/include/features.h we see:
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
It just so happens that the compilation of kdebase uses the -ansi
switch, hence the compilation problem. Now, I still don't know what the
correct solution is. Do we just kill the -ansi flag from kdebase's
compilation? Looking at linux/joystick.h, I can't see a way of fixing
it as int64_t isn't an ANSI type, right?
Regards,
Matt.
