127 | # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | |
128 | # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to | |
129 | # '$srcdir', '$srcdir/..', or '$srcdir/../..'. | |
130 | # | |
131 | # Of course, Automake must honor this variable whenever it calls a | |
132 | # tool from the auxiliary directory. The problem is that $srcdir (and | |
133 | # therefore $ac_aux_dir as well) can be either absolute or relative, | |
134 | # depending on how configure is run. This is pretty annoying, since | |
135 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
136 | # source directory, any form will work fine, but in subdirectories a | |
137 | # relative path needs to be adjusted first. | |
138 | # | |
139 | # $ac_aux_dir/missing | |
140 | # fails when called from a subdirectory if $ac_aux_dir is relative | |
141 | # $top_srcdir/$ac_aux_dir/missing | |
142 | # fails if $ac_aux_dir is absolute, | |
143 | # fails when called from a subdirectory in a VPATH build with | |
144 | # a relative $ac_aux_dir | |
145 | # | |
146 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
147 | # are both prefixed by $srcdir. In an in-source build this is usually | |
148 | # harmless because $srcdir is '.', but things will broke when you | |
149 | # start a VPATH build or use an absolute $srcdir. | |
150 | # | |
151 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
152 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
153 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
154 | # and then we would define $MISSING as | |
155 | # MISSING="\${SHELL} $am_aux_dir/missing" | |
156 | # This will work as long as MISSING is not called from configure, because | |
157 | # unfortunately $(top_srcdir) has no meaning in configure. | |
158 | # However there are other variables, like CC, which are often used in | |
159 | # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
160 | # | |
161 | # Another solution, used here, is to always expand $ac_aux_dir to an | |
162 | # absolute PATH. The drawback is that using absolute paths prevent a | |
163 | # configured tree to be moved without reconfiguration. | |
