| 2528 | 66 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
| 67 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to | |
| 68 # `$srcdir', `$srcdir/..', or `$srcdir/../..'. | |
| 69 # | |
| 70 # Of course, Automake must honor this variable whenever it calls a | |
| 71 # tool from the auxiliary directory. The problem is that $srcdir (and | |
| 72 # therefore $ac_aux_dir as well) can be either absolute or relative, | |
| 73 # depending on how configure is run. This is pretty annoying, since | |
| 74 # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
| 75 # source directory, any form will work fine, but in subdirectories a | |
| 76 # relative path needs to be adjusted first. | |
| 77 # | |
| 78 # $ac_aux_dir/missing | |
| 79 # fails when called from a subdirectory if $ac_aux_dir is relative | |
| 80 # $top_srcdir/$ac_aux_dir/missing | |
| 81 # fails if $ac_aux_dir is absolute, | |
| 82 # fails when called from a subdirectory in a VPATH build with | |
| 83 # a relative $ac_aux_dir | |
| 84 # | |
| 85 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
| 86 # are both prefixed by $srcdir. In an in-source build this is usually | |
| 87 # harmless because $srcdir is `.', but things will broke when you | |
| 88 # start a VPATH build or use an absolute $srcdir. | |
| 89 # | |
| 90 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
| 91 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
| 92 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
| 93 # and then we would define $MISSING as | |
| 94 # MISSING="\${SHELL} $am_aux_dir/missing" | |
| 95 # This will work as long as MISSING is not called from configure, because | |
| 96 # unfortunately $(top_srcdir) has no meaning in configure. | |
| 97 # However there are other variables, like CC, which are often used in | |
| 98 # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
| 99 # | |
| 100 # Another solution, used here, is to always expand $ac_aux_dir to an | |
| 101 # absolute PATH. The drawback is that using absolute paths prevent a | |
| 102 # configured tree to be moved without reconfiguration. | |
