== The build process == === Dependencies === In general, Pacemaker 3 will support dependency versions that are available in supported releases of major Linux distributions (usually but not always including long-term support releases). The following are specifically targeted for support: * Debian 10 "buster" and later * RHEL 8.0 and later * SUSE 15.0 and later * Ubuntu 18 "bionic" and later The only changes are these new minimum dependency versions: * libdbus 1.5.12 * libgnutls 3.1.7 (also now required rather than optional) * libqb 1.0.1 * libxml2 2.9.2 * pkg-config 0.28 (or pkgconf) * Python 3.6 * rpm 4.14.0 (if building RPMs) === configure script === The following configure script options are no longer supported: * `--enable-legacy-links` //(deprecated since Pacemaker 2.1.0)// * `--enable-compat-2.0` //(introduced in 2.1.0 explicitly for the 2.1 series only)// * `--enable-upstart` //(deprecated since Pacemaker 2.1.0)// * `--with-gnutls` //(GnuTLS is now required and cannot be disabled)// * `--with-nagios` //(deprecated since Pacemaker 2.1.6)// Additionally, the `--with-concurrent-fencing-default` option is now deprecated and defaults to true. === RPMs === * The `RPMDEST` Makefile variable may no longer be set to `toplevel`. The default of `subtree`, and explicit paths, are still supported. * The spec file now longer supports the `--with-doc` and `--without-doc` options. Documentation will always be built. * Pacemaker's logrotate script is now part of the pacemaker package instead of the pacemaker-cli package. * The `--with stonithd`/`--without stonithd` spec file option, which controls support for Linux-HA fencing agents, has been renamed to `--with linuxha/--without linuxha` * `build.counter`, used to set the RPM package version during development, is now looked for only in the `rpm` subdirectory, not the toplevel source directory. === Resource agents === * The obsolete and deprecated **ocf:pacemaker:o2cb** resource agent (which manages the no-longer-used ocf_controld.pcmk daemon for OCFS2 file systems) has been dropped.
