CPack DEB Generator ------------------- The built in (binary) CPack DEB generator (Unix only) Variables specific to CPack Debian (DEB) generator ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The CPack DEB generator may be used to create DEB package using :module:`CPack`. The CPack DEB generator is a :module:`CPack` generator thus it uses the ``CPACK_XXX`` variables used by :module:`CPack`. The CPack DEB generator should work on any Linux host but it will produce better deb package when Debian specific tools ``dpkg-xxx`` are usable on the build system. The CPack DEB generator has specific features which are controlled by the specifics ``CPACK_DEBIAN_XXX`` variables. ``CPACK_DEBIAN__XXXX`` variables may be used in order to have **component** specific values. Note however that ```` refers to the **grouping name** written in upper case. It may be either a component name or a component GROUP name. Here are some CPack DEB generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful: - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/Configuration - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/PackageGenerators#deb-unix-only List of CPack DEB generator specific variables: .. variable:: CPACK_DEB_COMPONENT_INSTALL Enable component packaging for CPackDEB * Mandatory : NO * Default : OFF If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated. .. variable:: CPACK_DEBIAN_PACKAGE_NAME CPACK_DEBIAN__PACKAGE_NAME Set Package control field (variable is automatically transformed to lower case). * Mandatory : YES * Default : - :variable:`CPACK_PACKAGE_NAME` for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_NAME` suffixed with - for component-based installations. See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source .. variable:: CPACK_DEBIAN_FILE_NAME CPACK_DEBIAN__FILE_NAME Package file name. * Mandatory : YES * Default : ``[-].deb`` This may be set to ``DEB-DEFAULT`` to allow the CPack DEB generator to generate package file name by itself in deb format:: _-_.deb Alternatively provided package file name must end with either ``.deb`` or ``.ipk`` suffix. .. note:: Preferred setting of this variable is ``DEB-DEFAULT`` but for backward compatibility with the CPack DEB generator in CMake prior to version 3.6 this feature is disabled by default. .. note:: By using non default filenames duplicate names may occur. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors. .. variable:: CPACK_DEBIAN_PACKAGE_EPOCH The Debian package epoch * Mandatory : No * Default : - Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages. .. variable:: CPACK_DEBIAN_PACKAGE_VERSION The Debian package version * Mandatory : YES * Default : :variable:`CPACK_PACKAGE_VERSION` This variable may contain only alphanumerics (A-Za-z0-9) and the characters . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If :variable:`CPACK_DEBIAN_PACKAGE_RELEASE` is not set then hyphens are not allowed. .. note:: For backward compatibility with CMake 3.9 and lower a failed test of this variable's content is not a hard error when both :variable:`CPACK_DEBIAN_PACKAGE_RELEASE` and :variable:`CPACK_DEBIAN_PACKAGE_EPOCH` variables are not set. An author warning is reported instead. .. variable:: CPACK_DEBIAN_PACKAGE_RELEASE The Debian package release - Debian revision number. * Mandatory : No * Default : - This is the numbering of the DEB package itself, i.e. the version of the packaging and not the version of the content (see :variable:`CPACK_DEBIAN_PACKAGE_VERSION`). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering. .. variable:: CPACK_DEBIAN_PACKAGE_ARCHITECTURE CPACK_DEBIAN__PACKAGE_ARCHITECTURE The Debian package architecture * Mandatory : YES * Default : Output of ``dpkg --print-architecture`` (or ``i386`` if ``dpkg`` is not found) .. variable:: CPACK_DEBIAN_PACKAGE_DEPENDS CPACK_DEBIAN__PACKAGE_DEPENDS Sets the Debian dependencies of this package. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_DEPENDS` for component-based installations. .. note:: If :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` or more specifically :variable:`CPACK_DEBIAN__PACKAGE_SHLIBDEPS` is set for this component, the discovered dependencies will be appended to :variable:`CPACK_DEBIAN__PACKAGE_DEPENDS` instead of :variable:`CPACK_DEBIAN_PACKAGE_DEPENDS`. If :variable:`CPACK_DEBIAN__PACKAGE_DEPENDS` is an empty string, only the automatically discovered dependencies will be set for this component. Example:: set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)") .. variable:: CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS Sets inter component dependencies if listed with :variable:`CPACK_COMPONENT__DEPENDS` variables. * Mandatory : NO * Default : - .. variable:: CPACK_DEBIAN_PACKAGE_MAINTAINER The Debian package maintainer * Mandatory : YES * Default : ``CPACK_PACKAGE_CONTACT`` .. variable:: CPACK_DEBIAN_PACKAGE_DESCRIPTION CPACK_DEBIAN__DESCRIPTION The Debian package description * Mandatory : YES * Default : - :variable:`CPACK_DEBIAN__DESCRIPTION` (component based installers only) if set, or :variable:`CPACK_DEBIAN_PACKAGE_DESCRIPTION` if set, or - :variable:`CPACK_COMPONENT__DESCRIPTION` (component based installers only) if set, or :variable:`CPACK_PACKAGE_DESCRIPTION` if set, or - content of the file specified in :variable:`CPACK_PACKAGE_DESCRIPTION_FILE` if set If after that description is not set, :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` going to be used if set. Otherwise, :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` will be added as the first line of description as defined in `Debian Policy Manual`_. .. _Debian Policy Manual: https://www.debian.org/doc/debian-policy/ch-controlfields.html#description .. variable:: CPACK_DEBIAN_PACKAGE_SECTION CPACK_DEBIAN__PACKAGE_SECTION Set Section control field e.g. admin, devel, doc, ... * Mandatory : YES * Default : "devel" See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections .. variable:: CPACK_DEBIAN_ARCHIVE_TYPE The archive format used for creating the Debian package. * Mandatory : YES * Default : "gnutar" Possible value is: - gnutar .. note:: This variable previously defaulted to the ``paxr`` value, but ``dpkg`` has never supported that tar format. For backwards compatibility the ``paxr`` value will be mapped to ``gnutar`` and a deprecation message will be emitted. .. variable:: CPACK_DEBIAN_COMPRESSION_TYPE The compression used for creating the Debian package. * Mandatory : YES * Default : "gzip" Possible values are: - lzma - xz - bzip2 - gzip .. variable:: CPACK_DEBIAN_PACKAGE_PRIORITY CPACK_DEBIAN__PACKAGE_PRIORITY Set Priority control field e.g. required, important, standard, optional, extra * Mandatory : YES * Default : "optional" See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities .. variable:: CPACK_DEBIAN_PACKAGE_HOMEPAGE The URL of the web site for this package, preferably (when applicable) the site from which the original source can be obtained and any additional upstream documentation or information may be found. * Mandatory : NO * Default : :variable:`CMAKE_PROJECT_HOMEPAGE_URL` .. note:: The content of this field is a simple URL without any surrounding characters such as <>. .. variable:: CPACK_DEBIAN_PACKAGE_SHLIBDEPS CPACK_DEBIAN__PACKAGE_SHLIBDEPS May be set to ON in order to use ``dpkg-shlibdeps`` to generate better package dependency list. * Mandatory : NO * Default : - :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` if set or - OFF .. note:: You may need set :variable:`CMAKE_INSTALL_RPATH` to an appropriate value if you use this feature, because if you don't ``dpkg-shlibdeps`` may fail to find your own shared libs. See https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/RPATH-handling .. variable:: CPACK_DEBIAN_PACKAGE_DEBUG May be set when invoking cpack in order to trace debug information during the CPack DEB generator run. * Mandatory : NO * Default : - .. variable:: CPACK_DEBIAN_PACKAGE_PREDEPENDS CPACK_DEBIAN__PACKAGE_PREDEPENDS Sets the `Pre-Depends` field of the Debian package. Like :variable:`Depends `, except that it also forces ``dpkg`` to complete installation of the packages named before even starting the installation of the package which declares the pre-dependency. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_PREDEPENDS` for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps .. variable:: CPACK_DEBIAN_PACKAGE_ENHANCES CPACK_DEBIAN__PACKAGE_ENHANCES Sets the `Enhances` field of the Debian package. Similar to :variable:`Suggests ` but works in the opposite direction: declares that a package can enhance the functionality of another package. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_ENHANCES` for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps .. variable:: CPACK_DEBIAN_PACKAGE_BREAKS CPACK_DEBIAN__PACKAGE_BREAKS Sets the `Breaks` field of the Debian package. When a binary package (P) declares that it breaks other packages (B), ``dpkg`` will not allow the package (P) which declares `Breaks` be **unpacked** unless the packages that will be broken (B) are deconfigured first. As long as the package (P) is configured, the previously deconfigured packages (B) cannot be reconfigured again. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_BREAKS` for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks .. variable:: CPACK_DEBIAN_PACKAGE_CONFLICTS CPACK_DEBIAN__PACKAGE_CONFLICTS Sets the `Conflicts` field of the Debian package. When one binary package declares a conflict with another using a `Conflicts` field, ``dpkg`` will not allow them to be unpacked on the system at the same time. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_CONFLICTS` for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts .. note:: This is a stronger restriction than :variable:`Breaks `, which prevents the broken package from being configured while the breaking package is in the "Unpacked" state but allows both packages to be unpacked at the same time. .. variable:: CPACK_DEBIAN_PACKAGE_PROVIDES CPACK_DEBIAN__PACKAGE_PROVIDES Sets the `Provides` field of the Debian package. A virtual package is one which appears in the `Provides` control field of another package. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_PROVIDES` for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual .. variable:: CPACK_DEBIAN_PACKAGE_REPLACES CPACK_DEBIAN__PACKAGE_REPLACES Sets the `Replaces` field of the Debian package. Packages can declare in their control file that they should overwrite files in certain other packages, or completely replace other packages. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_REPLACES` for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps .. variable:: CPACK_DEBIAN_PACKAGE_RECOMMENDS CPACK_DEBIAN__PACKAGE_RECOMMENDS Sets the `Recommends` field of the Debian package. Allows packages to declare a strong, but not absolute, dependency on other packages. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_RECOMMENDS` for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps .. variable:: CPACK_DEBIAN_PACKAGE_SUGGESTS CPACK_DEBIAN__PACKAGE_SUGGESTS Sets the `Suggests` field of the Debian package. Allows packages to declare a suggested package install grouping. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_SUGGESTS` for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps .. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS * Mandatory : NO * Default : OFF Allows to generate shlibs control file automatically. Compatibility is defined by :variable:`CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY` variable value. .. note:: Libraries are only considered if they have both library name and version set. This can be done by setting SOVERSION property with :command:`set_target_properties` command. .. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY Compatibility policy for auto-generated shlibs control file. * Mandatory : NO * Default : "=" Defines compatibility policy for auto-generated shlibs control file. Possible values: "=", ">=" See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-sharedlibs-shlibdeps .. variable:: CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA CPACK_DEBIAN__PACKAGE_CONTROL_EXTRA This variable allow advanced user to add custom script to the control.tar.gz. Typical usage is for conffiles, postinst, postrm, prerm. * Mandatory : NO * Default : - Usage:: set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA "${CMAKE_CURRENT_SOURCE_DIR}/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm") .. note:: The original permissions of the files will be used in the final package unless the variable :variable:`CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION` is set. In particular, the scripts should have the proper executable flag prior to the generation of the package. .. variable:: CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION CPACK_DEBIAN__PACKAGE_CONTROL_STRICT_PERMISSION This variable indicates if the Debian policy on control files should be strictly followed. * Mandatory : NO * Default : FALSE Usage:: set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE) .. note:: This overrides the permissions on the original files, following the rules set by Debian policy https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners .. variable:: CPACK_DEBIAN_PACKAGE_SOURCE CPACK_DEBIAN__PACKAGE_SOURCE Sets the ``Source`` field of the binary Debian package. When the binary package name is not the same as the source package name (in particular when several components/binaries are generated from one source) the source from which the binary has been generated should be indicated with the field ``Source``. * Mandatory : NO * Default : - An empty string for non-component based installations - :variable:`CPACK_DEBIAN_PACKAGE_SOURCE` for component-based installations. See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source .. note:: This value is not interpreted. It is possible to pass an optional revision number of the referenced source package as well. Packaging of debug information ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Dbgsym packages contain debug symbols for debugging packaged binaries. Dbgsym packaging has its own set of variables: .. variable:: CPACK_DEBIAN_DEBUGINFO_PACKAGE CPACK_DEBIAN__DEBUGINFO_PACKAGE Enable generation of dbgsym .ddeb package(s). * Mandatory : NO * Default : OFF .. note:: Binaries must contain debug symbols before packaging so use either ``Debug`` or ``RelWithDebInfo`` for :variable:`CMAKE_BUILD_TYPE` variable value. Building Debian packages on Windows ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ To communicate UNIX file permissions from the install stage to the CPack DEB generator the "cmake_mode_t" NTFS alternate data stream (ADT) is used. When a filesystem without ADT support is used only owner read/write permissions can be preserved. Reproducible packages ^^^^^^^^^^^^^^^^^^^^^ The environment variable ``SOURCE_DATE_EPOCH`` may be set to a UNIX timestamp, defined as the number of seconds, excluding leap seconds, since 01 Jan 1970 00:00:00 UTC. If set, the CPack DEB generator will use its value for timestamps in the package.
