Starting with ZoneMinder 1.26.4, ZoneMinder can now be installed using cmake. This requires cmake version 2.6 or newer.
cmake is an alternative to the autotools collection (libtool, autoconf, automake, autoheader and such). Its more recent and has many advantages, including, but not limited to:
* One program (cmake) instead of multiple. (libtool, autoconf, automake, etc)
* One file per directory (CMakeLists.txt) instead of multiple. (configure.ac, Makefile.am and sometimes more)
* One syntax (cmake's syntax) instead of multiple. (bash and m4)
* Generation of makefiles for many platforms, including Windows.
* Newer than autotools and is being actively developed.
* Generates colored makefiles with progress indicator.
* Slightly faster because its based on C and not bash.
At this point, its still possible to use autotools for the ZoneMinder project. Choosing cmake or autotools is now a matter of preference.
Hopefully in the future, cmake will become the default way to install ZoneMinder.
Important differences
---------------------
* Unlike the autotools way, the cmake way does not require any options. It attempts to detect some things by its own (system directories, libarch, web user and group) and uses defaults for others (installation paths and such).
* Unlike the autotools way, which links the binaries to a fixed list of libraries, the cmake way only links to libraries that it found on the system. If a library is not found, but required, a fatal error will be shown during the configuration step.
* Unlike the autotools way, the cmake way does not modify the system in any way it shouldnt. It only does what its supposed to do: Install files to your system. Nothing else and nothing leaks out of the DESTDIR environment variable (if used). This means that depending on your configuration, there might be an extra required step after installation: to link WEB_PATH/events and WEB_PATH/images folders to the correct places.
Configuration
-------------
cmake by default does not require any parameters, but its possible to override the defaults with the options below.
Configuration can be done in 4 ways:
1) As a command line parameter, e.g. cmake -DCMAKE_VERBOSE_MAKEFILE=ON .
ZM_PERL_MM_PARMS By default, ZoneMinder's Perl modules are installed into the Vendor folders, as defined by your installation of Perl. You can change that here. Consult Perl's MakeMaker documentation for a definition of acceptable parameters. If you set this to something that causes the modules to be installed outside Perl's normal serach path, then you will also need to set ZM_PERL_SEARCH_PATH accordingly. default: "INSTALLDIRS=vendor NO_PACKLIST=1 NO_PERLLOCAL=1"
ZM_PERL_SEARCH_PATH Use to add a folder to your Perl's search path. This will need to be set in cases where ZM_PERL_MM_PARMS has been modified such that ZoneMinder's Perl modules are installed outside Perl's default search path. default: ""
CMAKE_VERBOSE_MAKEFILE - Set this to ON (default OFF) to see what cmake is doing. Very useful for troubleshooting.
CMAKE_BUILD_TYPE - Set this to Debug (default Release) to build ZoneMinder with debugging enabled.
CMAKE_INSTALL_PREFIX - Use this to change the prefix (default /usr/local). This option behaves like --prefix from autoconf. Package maintainers will probably want to set this to "/usr".
CMAKE_INCLUDE_PATH - Use this to add to the include search path.
CMAKE_LIBRARY_PATH - Use this to add to the library search path.
CMAKE_PREFIX_PATH - Use this to add to both include and library search paths. <path>/include will be added to the include search path and <path>/lib to the library search path. Multiple paths can be specified, separated by a : character. For example: export CMAKE_PREFIX_PATH="/opt/libjpeg-turbo:/opt/ffmpeg-from-git"
The DESTDIR environment variable is also supported, however it needs to be set before invoking make install. For example: DESTDIR=mydestdir make install
3) Run "make install" (as root, or use sudo) to install ZoneMinder to your system.
4) Create a directory for the content and the necessary symlinks by running zmlinkcontent.sh with the directory you want to use. e.g. ./zmlinkcontent.sh /nfs/zm
5) Create a database for zoneminder, called "zm".
6) Create a user for the zoneminder database, called zmuser with password and full privileges to the "zm" database.
NOTE: The database server, database name, user and password can be different and adjusted during configuration step with the options in this file, or by editing /etc/zm.conf
7) Populate the zoneminder database using the script zm_create.sql. This should be found in <prefix>/share/zoneminder/db or in the project/db directory.
8) Create an apache virtual host for ZoneMinder. Make sure to use the same paths as ZM_WEBDIR and ZM_CGIDIR in /etc/zm.conf
9) Set date.timezone to your correct timezone in php.ini
10) Create other config if desired (e.g. rsyslog, logrotate and such). Some of this can be found in <prefix>/share/zoneminder/misc or project/misc directory
11) Setup an appropriate startup script for your system. Two generic startup scripts have been provided, a legacy Sys V Init script and a Systemd service file.
1) If you wish to use the same paths and configuration as the currently installed ZoneMinder, you need to provide cmake with options that match your current installation.
You can provide those options in the command line to cmake, e.g. cmake -DZM_DB_PASS="blah" -DZM_WEBDIR="/usr/local/share/zoneminder/www" -DCMAKE_INSTALL_FULL_BINDIR="/usr/bin" .
Or alternatively, for convenience, use the cmakecacheimport.sh script. This reads a zoneminder configuration file (zm.conf) and creates a cmake initial cache file called zm_conf.cmake, which you can then provide to cmake.
For example:
./cmakecacheimport.sh /etc/zm.conf
cmake -C zm_conf.cmake [extra options] .
2) Run "make" to compile ZoneMinder
3) Run "make install" (as root, or use sudo) to install ZoneMinder to your system.
4) Depending on your configuration: If the DIR_EVENTS and DIR_IMAGES options are set to default (pointing to web directory/events and web directory/images), You will need to update the symlinks in the web directory to the correct folders. e.g. web directory/events should point to the real events directory, and likewise for the images directory.
You can use the zmlinkcontent.sh script for this. For example, if /var/lib/zoneminder is the folder that contains the "images" and "events" directories, you can use:
./zmlinkcontent.sh /var/lib/zoneminder
By default, the content directory for new installations is /var/lib/zoneminder. This can be overridden in cmake with the ZM_CONTENTDIR option. e.g. cmake -DZM_CONTENTDIR="/some/big/storage/zm" .
5) Run zmupdate.pl to update the database layout to the new version.
By default, cmake does not have an uninstall target, however we have added a one. Simply run make uninstall (or DESTDIR=mydestdir make uninstall if a DESTDIR was used) and it will remove all the files that cmake installed.
It's also possible to do this manually. The file install_manifest.txt contains the list of files installed to the system. This can be used in many ways to delete all files installed by cmake, such as: xargs rm < install_manifest.txt
