40 dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed
41 dnl with the API version to also check the API compatibility. Example:
42 dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed
43 dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1. Using
44 dnl this features allows to prevent build against newer versions of libgcrypt
45 dnl with a changed API.

48 dnl searched in $SYSROOT/bin and then along $PATH. If the used
49 dnl config script does not match the host specification the script
50 dnl is added to the gpg_config_script_warn variable.

511 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

515 # Of course, Automake must honor this variable whenever it calls a
516 # tool from the auxiliary directory. The problem is that $srcdir (and
517 # therefore $ac_aux_dir as well) can be either absolute or relative,
518 # depending on how configure is run. This is pretty annoying, since
519 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
520 # source directory, any form will work fine, but in subdirectories a
521 # relative path needs to be adjusted first.

526 # fails if $ac_aux_dir is absolute,
527 # fails when called from a subdirectory in a VPATH build with
528 # a relative $ac_aux_dir
530 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
531 # are both prefixed by $srcdir. In an in-source build this is usually
532 # harmless because $srcdir is '.', but things will broke when you
533 # start a VPATH build or use an absolute $srcdir.
535 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
536 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
537 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

540 # This will work as long as MISSING is not called from configure, because
