Subject: legacy configure with --with-libtool loops forever if libtool is not installed MIME-Version: 1.0 X-Mailer: MIME-tools 5.505 (Entity 5.505) Content-Disposition: inline X-RT-Interface: Web Message-ID: Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: binary X-RT-Original-Encoding: utf-8 X-RT-Encrypt: 0 X-RT-Sign: 0 Content-Length: 841 Under Solaris11 when the legacy configure was used with --with-libtool -------------------------------------------------------------------- : checking for struct msghdr.msg_control... yes checking for struct tpacket_auxdata.tp_vlan_tci... no configure: WARNING: legacy configure is used but libtool is enabled.
