# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
| 42 |
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
| 43 |
# `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
| 44 |
# |
| 45 |
# Of course, Automake must honor this variable whenever it calls a |
| 46 |
# tool from the auxiliary directory. The problem is that $srcdir (and |
| 47 |
# therefore $ac_aux_dir as well) can be either absolute or relative, |
| 48 |
# depending on how configure is run. This is pretty annoying, since |
| 49 |
# it makes $ac_aux_dir quite unusable in subdirectories: in the top |
| 50 |
# source directory, any form will work fine, but in subdirectories a |
| 51 |
# relative path needs to be adjusted first. |
| 52 |
# |
| 53 |
# $ac_aux_dir/missing |
| 54 |
# fails when called from a subdirectory if $ac_aux_dir is relative |
| 55 |
# $top_srcdir/$ac_aux_dir/missing |
| 56 |
# fails if $ac_aux_dir is absolute, |
| 57 |
# fails when called from a subdirectory in a VPATH build with |
| 58 |
# a relative $ac_aux_dir |
| 59 |
# |
| 60 |
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
| 61 |
# are both prefixed by $srcdir. In an in-source build this is usually |
| 62 |
# harmless because $srcdir is `.', but things will broke when you |
| 63 |
# start a VPATH build or use an absolute $srcdir. |
| 64 |
# |
| 65 |
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
| 66 |
# iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
| 67 |
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
| 68 |
# and then we would define $MISSING as |
| 69 |
# MISSING="\${SHELL} $am_aux_dir/missing" |
| 70 |
# This will work as long as MISSING is not called from configure, because |
| 71 |
# unfortunately $(top_srcdir) has no meaning in configure. |
| 72 |
# However there are other variables, like CC, which are often used in |
| 73 |
# configure, and could therefore not use this "fixed" $ac_aux_dir. |
| 74 |
# |
| 75 |
# Another solution, used here, is to always expand $ac_aux_dir to an |
| 76 |
# absolute PATH. The drawback is that using absolute paths prevent a |
| 77 |
# configured tree to be moved without reconfiguration. |

# Check whether `mkdir -p' is supported, fallback to mkinstalldirs otherwise. |
| 1523 |
# |
| 1524 |
# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories |
| 1525 |
# created by `make install' are always world readable, even if the |
| 1526 |
# installer happens to have an overly restrictive umask (e.g. 077). |
| 1527 |
# This was a mistake. There are at least two reasons why we must not |
| 1528 |
# use `-m 0755': |
| 1529 |
# - it causes special bits like SGID to be ignored, |
| 1530 |
# - it may be too restrictive (some setups expect 775 directories). |
| 1531 |
# |
| 1532 |
# Do not use -m 0755 and let people choose whatever they expect by |
| 1533 |
# setting umask. |
| 1534 |
# |
| 1535 |
# We cannot accept any implementation of `mkdir' that recognizes `-p'. |
| 1536 |
# Some implementations (such as Solaris 8's) are not thread-safe: if a |
| 1537 |
# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c' |
| 1538 |
# concurrently, both version can detect that a/ is missing, but only |
| 1539 |
# one can create it and the other will error out. Consequently we |
| 1540 |
# restrict ourselves to GNU make (using the --version option ensures |
| 1541 |
# this.) |
