# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to

224

# `$srcdir', `$srcdir/..', or `$srcdir/../..'.

225

#

226

# Of course, Automake must honor this variable whenever it calls a

227

# tool from the auxiliary directory. The problem is that $srcdir (and

228

# therefore $ac_aux_dir as well) can be either absolute or relative,

229

# depending on how configure is run. This is pretty annoying, since

230

# it makes $ac_aux_dir quite unusable in subdirectories: in the top

231

# source directory, any form will work fine, but in subdirectories a

232

# relative path needs to be adjusted first.

233

#

234

# $ac_aux_dir/missing

235

# fails when called from a subdirectory if $ac_aux_dir is relative

236

# $top_srcdir/$ac_aux_dir/missing

237

# fails if $ac_aux_dir is absolute,

238

# fails when called from a subdirectory in a VPATH build with

239

# a relative $ac_aux_dir

240

#

241

# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

242

# are both prefixed by $srcdir. In an in-source build this is usually

243

# harmless because $srcdir is `.', but things will broke when you

244

# start a VPATH build or use an absolute $srcdir.

245

#

246

# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

247

# iff we strip the leading $srcdir from $ac_aux_dir. That would be:

248

# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*$.*$"`

249

# and then we would define $MISSING as

250

# MISSING="\${SHELL} $am_aux_dir/missing"

251

# This will work as long as MISSING is not called from configure, because

252

# unfortunately $(top_srcdir) has no meaning in configure.

253

# However there are other variables, like CC, which are often used in

254

# configure, and could therefore not use this "fixed" $ac_aux_dir.

255

#

256

# Another solution, used here, is to always expand $ac_aux_dir to an

257

# absolute PATH. The drawback is that using absolute paths prevent a
