1dnl ###################################################################### 2dnl Find name of mount table file, and define it as MNTTAB_FILE_NAME 3dnl 4dnl Solaris defines MNTTAB as /etc/mnttab, the file where /sbin/mount 5dnl stores its cache of mounted filesystems. But under SunOS, the same 6dnl macro MNTTAB, is defined as the _source_ of filesystems to mount, and 7dnl is set to /etc/fstab. That is why I have to first check out 8dnl if MOUNTED exists, and if not, check for the MNTTAB macro. 9dnl 10AC_DEFUN([AMU_CHECK_MNTTAB_FILE_NAME], 11[ 12AC_CACHE_CHECK(for name of mount table file name, 13ac_cv_mnttab_file_name, 14[ 15# expand cpp value for MNTTAB 16AMU_EXPAND_CPP_STRING( 17AMU_MOUNT_HEADERS( 18[ 19/* see M4 comment at the top of the definition of this macro */ 20#ifdef MOUNTED 21# define _MNTTAB_FILE_NAME MOUNTED 22# else /* not MOUNTED */ 23# ifdef MNTTAB 24# define _MNTTAB_FILE_NAME MNTTAB 25# endif /* MNTTAB */ 26#endif /* not MOUNTED */ 27]), 28_MNTTAB_FILE_NAME, 29[ ac_cv_mnttab_file_name=$value 30], 31[ 32ac_cv_mnttab_file_name=notfound 33# check explicitly for /etc/mnttab 34if test "$ac_cv_mnttab_file_name" = notfound 35then 36 if test -f /etc/mnttab 37 then 38 ac_cv_mnttab_file_name="/etc/mnttab" 39 fi 40fi 41# check explicitly for /etc/mtab 42if test "$ac_cv_mnttab_file_name" = notfound 43then 44 if test -f /etc/mtab 45 then 46 ac_cv_mnttab_file_name="/etc/mtab" 47 fi 48fi 49]) 50]) 51# test value and create macro as needed 52if test "$ac_cv_mnttab_file_name" != notfound 53then 54 AC_DEFINE_UNQUOTED(MNTTAB_FILE_NAME, "$ac_cv_mnttab_file_name") 55fi 56]) 57dnl ====================================================================== 58
