72

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

73

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

74

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

75

#

76

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

77

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

78

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

79

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

80

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

81

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

82

# relative path needs to be adjusted first.

83

#

84

# $ac_aux_dir/missing

85

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

86

# $top_srcdir/$ac_aux_dir/missing

87

# fails if $ac_aux_dir is absolute,

88

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

89

# a relative $ac_aux_dir

90

#

91

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

92

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

93

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

94

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

95

#

96

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

97

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

98

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

99

# and then we would define $MISSING as

100

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

101

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

102

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

103

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

104

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

105

#

106

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

107

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

108

# configured tree to be moved without reconfiguration.
