| 21 | |
| 22 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | |
| 23 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to | |
| 24 # `$srcdir', `$srcdir/..', or `$srcdir/../..'. | |
| 25 # | |
| 26 # Of course, Automake must honor this variable whenever it calls a | |
| 27 # tool from the auxiliary directory. The problem is that $srcdir (and | |
| 28 # therefore $ac_aux_dir as well) can be either absolute or relative, | |
| 29 # depending on how configure is run. This is pretty annoying, since | |
| 30 # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
| 31 # source directory, any form will work fine, but in subdirectories a | |
| 32 # relative path needs to be adjusted first. | |
| 33 # | |
| 34 # $ac_aux_dir/missing | |
| 35 # fails when called from a subdirectory if $ac_aux_dir is relative | |
| 36 # $top_srcdir/$ac_aux_dir/missing | |
| 37 # fails if $ac_aux_dir is absolute, | |
| 38 # fails when called from a subdirectory in a VPATH build with | |
| 39 # a relative $ac_aux_dir | |
| 40 # | |
| 41 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
| 42 # are both prefixed by $srcdir. In an in-source build this is usually | |
| 43 # harmless because $srcdir is `.', but things will broke when you | |
| 44 # start a VPATH build or use an absolute $srcdir. | |
| 45 # | |
| 46 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
| 47 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
| 48 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
| 49 # and then we would define $MISSING as | |
| 50 # MISSING="\${SHELL} $am_aux_dir/missing" | |
| 51 # This will work as long as MISSING is not called from configure, because | |
| 52 # unfortunately $(top_srcdir) has no meaning in configure. | |
| 53 # However there are other variables, like CC, which are often used in | |
| 54 # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
| 55 # | |
| 56 # Another solution, used here, is to always expand $ac_aux_dir to an | |
| 57 # absolute PATH. The drawback is that using absolute paths prevent a | |
| 58 # configured tree to be moved without reconfiguration. | |
