Hello,
I have AC_CHECK_FUNCS which looks for getloadavg(). This works with
gcc 2.95 but fails on FreeBSD 5.2 where gcc has version 3.3.3.
On FreeBSD 5.2 configure claims that getloadavg() is not available.
configure.in:
AC_INIT(configure.in)
AC_PREREQ([2.50])
dnl AC_LANG(C++)
AC_LANG_CPLUSPLUS
AC_CHECK_FUNCS(failed getloadavg sysctlbyname)
AC_OUTPUT(Makefile)
config.log:
configure:1661: checking for getloadavg
configure:1704: g++ -o conftest -g -O2 conftest.cc >&5
configure:1676: error: declaration of C function `char getloadavg()' conflicts
with
/usr/include/stdlib.h:258: error: previous declaration `int getloadavg(double*,
int)' here
configure:1707: $? = 1
configure: failed program was:
#line 1666 "configure"
#include "confdefs.h"
/* System header to define __stub macros and hopefully few prototypes,
which can conflict with char getloadavg (); below. */
#include <assert.h>
/* Override any gcc2 internal prototype to avoid an error. */
#ifdef __cplusplus
extern "C"
#endif
/* We use char because int might match the return type of a gcc2
builtin and then its argument prototype would still apply. */
char getloadavg ();
char (*f) ();
#ifdef F77_DUMMY_MAIN
# ifdef __cplusplus
extern "C"
# endif
int F77_DUMMY_MAIN() { return 1; }
#endif
int
main ()
{
/* The GNU C library defines this for functions which it implements
to always fail with ENOSYS. Some functions are actually named
something starting with __ and the normal name is an alias. */
#if defined (__stub_getloadavg) || defined (__stub___getloadavg)
choke me
#else
f = getloadavg;
#endif
;
return 0;
}
configure:1723: result: no
How should this be solved?
How can one make gcc 3.3.3 work with getloadavg()?
