dnl Test for libgcrypt and define LIBGCRYPT_CFLAGS and LIBGCRYPT_LIBS.

dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed

dnl with the API version to also check the API compatibility. Example:

dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed

dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1.  Using

dnl this features allows to prevent build against newer versions of libgcrypt

dnl with a changed API.

dnl

dnl If a prefix option is not used, the config script is first

dnl searched in $SYSROOT/bin and then along $PATH.  If the used

dnl config script does not match the host specification the script

dnl is added to the gpg_config_script_warn variable.

# This file is free software; the Free Software Foundation

# 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"
