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