There are at least two reasons why we must not +# use `-m 0755': +# - it causes special bits like SGID to be ignored, +# - it may be too restrictive (some setups expect 775 directories). +# +# Do not use -m 0755 and let people choose whatever they expect by +# setting umask. +# +# We cannot accept any implementation of `mkdir' that recognizes `-p'. +# Some implementations (such as Solaris 8's) are vulnerable to race conditions: +# if a parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c' +# concurrently, both version can detect that a/ is missing, but only +# one can create it and the other will error out. Consequently we +# restrict ourselves to known race-free implementations. +# +# Automake used to define mkdir_p as `mkdir -p .', in order to +# allow $(mkdir_p) to be used without argument. As in +# $(mkdir_p) $(somedir) +# where $(somedir) is conditionally defined. However we don't do +# that for MKDIR_P. +# 1. before we restricted the check to GNU mkdir, `mkdir -p .' was +# reported to fail in read-only directories. The system where this +# happened has been forgotten. +# 2. in practice we call $(MKDIR_P) on directories such as +# $(MKDIR_P) "$(DESTDIR)$(somedir)" +# and we don't want to create $(DESTDIR) if $(somedir) is empty. +# To support the latter case, we have to write +# test -z "$(somedir)" || $(MKDIR_P) "$(DESTDIR)$(somedir)" +# so $(MKDIR_P) always has an argument. +# We will have better chances of detecting a missing test if +# $(MKDIR_P) complains about missing arguments. +# 3. $(MKDIR_P) is named after `mkdir -p' and we don't expect this +# to accept no argument. +# 4. having something like `mkdir .' in the output is unsightly. +# +# On NextStep and OpenStep, the `mkdir' command does not +# recognize any option. It will interpret all options as +# directories to create. +AN_MAKEVAR([MKDIR_P], [AC_PROG_MKDIR_P]) +AC_DEFUN_ONCE([AC_PROG_MKDIR_P], +[AC_REQUIRE([AC_CONFIG_AUX_DIR_DEFAULT])dnl + +AC_MSG_CHECKING([for a thread-safe mkdir -p]) +if test -z "$MKDIR_P"; then + AC_CACHE_VAL([ac_cv_path_mkdir], + [_AS_PATH_WALK([$PATH$PATH_SEPARATOR/opt/sfw/bin], + [for ac_prog in mkdir gmkdir; do + for ac_exec_ext in '' $ac_executable_extensions; do + AS_EXECUTABLE_P(["$as_dir/$ac_prog$ac_exec_ext"]) || continue + case `"$as_dir/$ac_prog$ac_exec_ext" --version 2>&1` in #( + 'mkdir (GNU coreutils) '* | \ + 'mkdir (coreutils) '* | \ + 'mkdir (fileutils) '4.1*) + ac_cv_path_mkdir=$as_dir/$ac_prog$ac_exec_ext + break 3;; + esac + done + done])]) + test -d ./--version && rmdir ./--version + if test "${ac_cv_path_mkdir+set}" = set; then + MKDIR_P="$ac_cv_path_mkdir -p" + else + # As a last resort, use the slow shell script.
