>Description:
One of the configure checks is faulty.
Specifically, this one:
# Check 3rd argument of getthostbyname_r
ac_save_CXXFLAGS="$CXXFLAGS"
AC_CACHE_CHECK([3 argument to gethostname_r routines],
mysql_cv_gethostname_arg,
AC_LANG_SAVE
AC_LANG_CPLUSPLUS
if test "$ac_cv_prog_gxx" = "yes"
then
CXXFLAGS="$CXXFLAGS -Werror"
fi
AC_TRY_COMPILE(
[#if !defined(SCO) && !defined(__osf__)
#define _REENTRANT
#endif
#include <pthread.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>],
[int skr;
skr = gethostbyname_r((const char *) 0, (struct hostent*) 0,
(hostent_data*) 0)
;],
mysql_cv_gethostname_arg=hostent_data, mysql_cv_gethostname_arg=char))
AC_LANG_RESTORE
CXXFLAGS="$ac_save_CXXFLAGS"
if test "$mysql_cv_gethostname_arg" = "hostent_data"
then
AC_DEFINE(HAVE_GETHOSTBYNAME_R_RETURN_INT)
fi
Now, this check fails because there IS NO "hostent_data" on my system.
"info libc" says:
- Function: int gethostbyname_r (const char *restrict NAME, struct
hostent *restrict RESULT_BUF, char *restrict BUF, size_t
BUFLEN, struct hostent **restrict RESULT, int *restrict
H_ERRNOP)
>How-To-Repeat:
Try to compile on my system. ;-)
>Fix:
Hmmm...
