67

# 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.
