Hello, I'm trying to build the current version CLN from git and having problems with autoreconf. As far as I understand, building CLN should work like that: "Checkout git to cln/" cd cln/ autoreconf -iv ./configure && make However, autoreconf tells me: $ autoreconf -iv autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal -I m4 autoreconf: configure.ac: tracing autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf configure.ac:64: error: possibly undefined macro: AC_DISABLE_SHARED If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.ac:68: error: possibly undefined macro: AC_ENABLE_SHARED configure.ac:71: error: possibly undefined macro: AC_PROG_LIBTOOL autoreconf: /usr/bin/autoconf failed with exit status: 1 I use the cln_1-3-4 tag on an ubuntu 16.10 with autoreconf 2.69.
