|
# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
# `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
# |
# Of course, Automake must honor this variable whenever it calls a |
# tool from the auxiliary directory. The problem is that $srcdir (and |
# therefore $ac_aux_dir as well) can be either absolute or relative, |
# depending on how configure is run. This is pretty annoying, since |
# it makes $ac_aux_dir quite unusable in subdirectories: in the top |
# source directory, any form will work fine, but in subdirectories a |
# relative path needs to be adjusted first. |
# |
# $ac_aux_dir/missing |
# fails when called from a subdirectory if $ac_aux_dir is relative |
# $top_srcdir/$ac_aux_dir/missing |
# fails if $ac_aux_dir is absolute, |
# fails when called from a subdirectory in a VPATH build with |
# a relative $ac_aux_dir |
# |
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
# are both prefixed by $srcdir. In an in-source build this is usually |
# harmless because $srcdir is `.', but things will broke when you |
# start a VPATH build or use an absolute $srcdir. |
# |
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
# iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
# and then we would define $MISSING as |
# MISSING="\${SHELL} $am_aux_dir/missing" |
# This will work as long as MISSING is not called from configure, because |
# unfortunately $(top_srcdir) has no meaning in configure. |
# However there are other variables, like CC, which are often used in |
# configure, and could therefore not use this "fixed" $ac_aux_dir. |
# |
# Another solution, used here, is to always expand $ac_aux_dir to an |
# absolute PATH. The drawback is that using absolute paths prevent a |
# configured tree to be moved without reconfiguration. |

# - 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 not thread-safe: if a |
# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c' |
