# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
68 |
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to |
69 |
# '$srcdir', '$srcdir/..', or '$srcdir/../..'. |
70 |
# |
71 |
# Of course, Automake must honor this variable whenever it calls a |
72 |
# tool from the auxiliary directory. The problem is that $srcdir (and |
73 |
# therefore $ac_aux_dir as well) can be either absolute or relative, |
74 |
# depending on how configure is run. This is pretty annoying, since |
75 |
# it makes $ac_aux_dir quite unusable in subdirectories: in the top |
76 |
# source directory, any form will work fine, but in subdirectories a |
77 |
# relative path needs to be adjusted first. |
78 |
# |
79 |
# $ac_aux_dir/missing |
80 |
# fails when called from a subdirectory if $ac_aux_dir is relative |
81 |
# $top_srcdir/$ac_aux_dir/missing |
82 |
# fails if $ac_aux_dir is absolute, |
83 |
# fails when called from a subdirectory in a VPATH build with |
84 |
# a relative $ac_aux_dir |
85 |
# |
86 |
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
87 |
# are both prefixed by $srcdir. In an in-source build this is usually |
88 |
# harmless because $srcdir is '.', but things will broke when you |
89 |
# start a VPATH build or use an absolute $srcdir. |
90 |
# |
91 |
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
92 |
# iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
93 |
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
94 |
# and then we would define $MISSING as |
95 |
# MISSING="\${SHELL} $am_aux_dir/missing" |
96 |
# This will work as long as MISSING is not called from configure, because |
97 |
# unfortunately $(top_srcdir) has no meaning in configure. |
98 |
# However there are other variables, like CC, which are often used in |
99 |
# configure, and could therefore not use this "fixed" $ac_aux_dir. |
100 |
# |
101 |
# Another solution, used here, is to always expand $ac_aux_dir to an |
102 |
# absolute PATH. The drawback is that using absolute paths prevent a |
103 |
# configured tree to be moved without reconfiguration. |
