Ugh, It's a pity one can't nicely override AC_ARG_WITH. It seems that the first use of --with[out]-whatever should take precedence. I'll probably do this in coreutils configure.ac before gl_INIT, so as to at least set the default as coreutils wants and caters for, and allowing users to --without-openssl if they want. dnl Enable use of libcrypto by default AS_VAR_SET_IF([with_openssl], [], [with_openssl=maybe]) > Come to think of it, the GNU coding standards say that > --with-openssl should configure the system to use the > OpenSSL library (and fail if it's not available, presumably; > that's what gl_GC and gl_LIBSELINUX do), but the recently-added > code doesn't do that; it issues a warning and disables the > library instead. Maybe we should be more consistent with > the rest of Gnulib here? Hmm, I don't think the above mentioned fail if not available? I'm using "maybe" above anyway, so that "yes" may be treated like this in future. thanks, Pádraig.
