| 890 | # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
| 891 | # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
| 892 | # `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
| 893 | # |
| 894 | # Of course, Automake must honor this variable whenever it calls a |
| 895 | # tool from the auxiliary directory. The problem is that $srcdir (and |
| 896 | # therefore $ac_aux_dir as well) can be either absolute or relative, |
| 897 | # depending on how configure is run. This is pretty annoying, since |
| 898 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
| 899 | # source directory, any form will work fine, but in subdirectories a |
| 900 | # relative path needs to be adjusted first. |
| 901 | # |
| 902 | # $ac_aux_dir/missing |
| 903 | # fails when called from a subdirectory if $ac_aux_dir is relative |
| 904 | # $top_srcdir/$ac_aux_dir/missing |
| 905 | # fails if $ac_aux_dir is absolute, |
| 906 | # fails when called from a subdirectory in a VPATH build with |
| 907 | # a relative $ac_aux_dir |
| 908 | # |
| 909 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
| 910 | # are both prefixed by $srcdir. In an in-source build this is usually |
| 911 | # harmless because $srcdir is `.', but things will broke when you |
| 912 | # start a VPATH build or use an absolute $srcdir. |
| 913 | # |
| 914 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
| 915 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
| 916 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
| 917 | # and then we would define $MISSING as |
| 918 | # MISSING="\${SHELL} $am_aux_dir/missing" |
| 919 | # This will work as long as MISSING is not called from configure, because |
| 920 | # unfortunately $(top_srcdir) has no meaning in configure. |
| 921 | # However there are other variables, like CC, which are often used in |
| 922 | # configure, and could therefore not use this "fixed" $ac_aux_dir. |
| 923 | # |
| 924 | # Another solution, used here, is to always expand $ac_aux_dir to an |
| 925 | # absolute PATH. The drawback is that using absolute paths prevent a |
