FWIW, I suggest to use this in configure.ac:
NEED_LIBGCRYPT_API=1
NEED_LIBGCRYPT_VERSION=1.4.0
# other configure stuff
AC_DEFINE_UNQUOTED(NEED_LIBGCRYPT_VERSION, "$NEED_LIBGCRYPT_VERSION",
[Required version of Libgcrypt])
AM_PATH_LIBGCRYPT("$NEED_LIBGCRYPT_API:$NEED_LIBGCRYPT_VERSION",
have_libgcrypt=yes,have_libgcrypt=no)
# close to the end use MSG_NOTICE or MSG_ERROR
if test "$have_libgcrypt" = "no"; then
die=yes
AC_MSG_NOTICE([[
***
*** You need libgcrypt to build this program.
** This library is for example available at
*** ftp://ftp.gnupg.org/gcrypt/libgcrypt/
*** (at least version $NEED_LIBGCRYPT_VERSION using API $NEED_LIBGCRYPT_API
is required.)
***]])
fi
In the code use:
if (!gcry_check_version (NEED_LIBGCRYPT_VERSION) )
OOPS();
Salam-Shalom,
