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

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

226

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

227

#

228

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

229

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

230

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

231

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

232

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

233

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

234

# relative path needs to be adjusted first.

235

#

236

# $ac_aux_dir/missing

237

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

238

# $top_srcdir/$ac_aux_dir/missing

239

# fails if $ac_aux_dir is absolute,

240

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

241

# a relative $ac_aux_dir

242

#

243

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

244

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

245

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

246

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

247

#

248

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

249

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

250

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

251

# and then we would define $MISSING as

252

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

253

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

254

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

255

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

256

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

257

#

258

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

259

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