AX_WITH_APXS([value-if-not-found], [path])
0.5.55 : djmitche
Dustin Mitchell <dustin@cs.uchicago.edu>
Locates an installed apxs binary, placing the result in the precious variable $APXS. Accepts a preset $APXS, then --with-apxs, and failing that searches for apxs in the given path (which defaults to the system path). If apxs is found, $APXS is set to the full path of the binary; otherwise it is set to VALUE-IF-NOT-FOUND, which defaults to apxs.
Example:
AX_WITH_APXS(missing)
AC_DEFUN([AX_WITH_APXS], [ AC_ARG_VAR([APXS]) dnl unless APXS was supplied to us (as a precious variable) if test -z "$APXS" then AC_MSG_CHECKING(for --with-apxs) AC_ARG_WITH(apxs, AC_HELP_STRING([--with-apxs=APXS], [absolute path name of apxs executable]), [ if test "$withval" != "yes" then APXS="$withval" AC_MSG_RESULT($withval) else AC_MSG_RESULT(no) fi ], [ AC_MSG_RESULT(no) ]) fi dnl if it's still not found, check the paths, or use the fallback if test -z "$APXS" then AC_PATH_PROG([APXS], apxs, m4_ifval([$1],[$1],[apxs]), $2) fi ])
