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 CPack. The CPack DEB generator is a CPack generator thus it uses the CPACK_XXX variables used by 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_<COMPONENT>_XXXX variables may be used in order to have component specific values. Note however that <COMPONENT> 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Here are some CPack DEB generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:

List of CPack DEB generator specific variables:

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.

CPACK_DEBIAN_PACKAGE_NAME
CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME

Set Package control field (variable is automatically transformed to lower case).

Mandatory:

Yes

Default:

在 3.5 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME variables.

See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source

CPACK_DEBIAN_FILE_NAME
CPACK_DEBIAN_<COMPONENT>_FILE_NAME

在 3.6 版被加入.

Package file name.

Mandatory:

Yes

Default:

<CPACK_PACKAGE_FILE_NAME>[-<component>].deb

This may be set to:

DEB-DEFAULT

Tell CPack to automatically generate the package file name in deb format:

<PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb

This setting recommended as the preferred behavior, but for backward compatibility with the CPack DEB generator in CMake prior to version 3.6, this is not the default. Without this, 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.

<file-name>[.deb]

Use the given file name.

在 3.29 版的變更: The .deb suffix will be automatically added if the file name does not end in .deb or .ipk. Previously the suffix was required.

<file-name>.ipk

在 3.10 版被加入.

Use the given file name. The .ipk suffix is used by the OPKG packaging system.

CPACK_DEBIAN_PACKAGE_EPOCH

在 3.10 版被加入.

The Debian package epoch

Mandatory:

No

Default:

None

Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.

CPACK_DEBIAN_PACKAGE_VERSION

The Debian package version

Mandatory:

Yes

Default:

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 CPACK_DEBIAN_PACKAGE_RELEASE is not set then hyphens are not allowed.

備註

For backward compatibility with CMake 3.9 and lower a failed test of this variable's content is not a hard error when both CPACK_DEBIAN_PACKAGE_RELEASE and CPACK_DEBIAN_PACKAGE_EPOCH variables are not set. An author warning is reported instead.

CPACK_DEBIAN_PACKAGE_RELEASE

在 3.6 版被加入.

The Debian package release - Debian revision number.

Mandatory:

No

Default:

None

This is the numbering of the DEB package itself, i.e. the version of the packaging and not the version of the content (see 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.

CPACK_DEBIAN_PACKAGE_ARCHITECTURE
CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE

The Debian package architecture

Mandatory:

Yes

Default:

Output of dpkg --print-architecture (or i386 if dpkg is not found)

在 3.6 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE variables.

CPACK_DEBIAN_PACKAGE_DEPENDS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS

Sets the Debian dependencies of this package.

Mandatory:

No

Default:

在 3.3 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS variables.

備註

If CPACK_DEBIAN_PACKAGE_SHLIBDEPS or more specifically CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS is set for this component, the discovered dependencies will be appended to CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS instead of CPACK_DEBIAN_PACKAGE_DEPENDS. If CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS is an empty string, only the automatically discovered dependencies will be set for this component.

在 3.31 版的變更: The variable is always expanded as a list. Before it was expanded only if used in cooperation with CPACK_DEB_COMPONENT_INSTALL, CPACK_DEBIAN_PACKAGE_SHLIBDEPS or CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS. This meant that if a component had no shared libraries discovered (e.g. a package composed only of scripts) you had to join the list by yourself to obtain a valid Depends field.

Example:

set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")
list(APPEND CPACK_DEBIAN_PACKAGE_DEPENDS cmake)
CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS

在 3.6 版被加入.

Sets inter-component dependencies if listed with CPACK_COMPONENT_<compName>_DEPENDS variables.

Mandatory:

No

Default:

None

CPACK_DEBIAN_PACKAGE_MAINTAINER

The Debian package maintainer

Mandatory:

Yes

Default:

CPACK_PACKAGE_CONTACT

CPACK_DEBIAN_PACKAGE_DESCRIPTION
CPACK_DEBIAN_<COMPONENT>_DESCRIPTION

The Debian package description

Mandatory:

Yes

Default:

If after that description is not set, CPACK_PACKAGE_DESCRIPTION_SUMMARY going to be used if set. Otherwise, CPACK_PACKAGE_DESCRIPTION_SUMMARY will be added as the first line of description as defined in Debian Policy Manual.

在 3.3 版被加入: Per-component CPACK_COMPONENT_<compName>_DESCRIPTION variables.

在 3.16 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_DESCRIPTION variables.

在 3.16 版被加入: The CPACK_PACKAGE_DESCRIPTION_FILE variable.

CPACK_DEBIAN_PACKAGE_SECTION
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION

Set Section control field e.g. admin, devel, doc, ...

Mandatory:

Yes

Default:

devel

在 3.5 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION variables.

See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections

CPACK_DEBIAN_ARCHIVE_TYPE

在 3.7 版被加入.

在 3.14 版之後被棄用.

The archive format used for creating the Debian package.

Mandatory:

Yes

Default:

gnutar

Possible value is: gnutar

備註

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.

CPACK_DEBIAN_COMPRESSION_TYPE

在 3.1 版被加入.

The compression used for creating the Debian package.

Mandatory:

Yes

Default:

gzip

Possible values are:

lzma

Lempel–Ziv–Markov chain algorithm

xz

XZ Utils compression

bzip2

bzip2 Burrows–Wheeler algorithm

gzip

GNU Gzip compression

zstd

在 3.22 版被加入.

Zstandard compression

CPACK_DEBIAN_PACKAGE_PRIORITY
CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY

Set Priority control field e.g. required, important, standard, optional, extra

Mandatory:

Yes

Default:

optional

在 3.5 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY variables.

See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities

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:

CMAKE_PROJECT_HOMEPAGE_URL

在 3.12 版被加入: The CMAKE_PROJECT_HOMEPAGE_URL variable.

備註

The content of this field is a simple URL without any surrounding characters such as <>.

CPACK_DEBIAN_PACKAGE_SHLIBDEPS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS

May be set to ON in order to use dpkg-shlibdeps to generate better package dependency list.

Mandatory:

No

Default:

備註

You may need set 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

備註

You can also set CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS to an appropriate value if you use this feature, in order to please dpkg-shlibdeps. However, you should only do this for private shared libraries that could not get resolved otherwise.

在 3.3 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS variables.

在 3.6 版被加入: Correct handling of $ORIGIN in CMAKE_INSTALL_RPATH.

CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS

在 3.20 版被加入.

May be set to a list of directories that will be given to dpkg-shlibdeps via its -l option. These will be searched by dpkg-shlibdeps in order to find private shared library dependencies.

Mandatory:

No

Default:

None

備註

You should prefer to set CMAKE_INSTALL_RPATH to an appropriate value if you use dpkg-shlibdeps. The current option is really only needed for private shared library dependencies.

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:

None

CPACK_DEBIAN_PACKAGE_PREDEPENDS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS

Sets the Pre-Depends field of the Debian package. Like 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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_ENHANCES
CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES

Sets the Enhances field of the Debian package. Similar to Suggests but works in the opposite direction: declares that a package can enhance the functionality of another package.

Mandatory:

No

Default:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_BREAKS
CPACK_DEBIAN_<COMPONENT>_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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks

CPACK_DEBIAN_PACKAGE_CONFLICTS
CPACK_DEBIAN_<COMPONENT>_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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

備註

This is a stronger restriction than 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.

CPACK_DEBIAN_PACKAGE_PROVIDES
CPACK_DEBIAN_<COMPONENT>_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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual

CPACK_DEBIAN_PACKAGE_REPLACES
CPACK_DEBIAN_<COMPONENT>_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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_RECOMMENDS
CPACK_DEBIAN_<COMPONENT>_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:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_SUGGESTS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS

Sets the Suggests field of the Debian package. Allows packages to declare a suggested package install grouping.

Mandatory:

No

Default:

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS variables.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS

在 3.6 版被加入.

Mandatory:

No

Default:

OFF

Allows to generate shlibs control file automatically. Compatibility is defined by CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY variable value.

備註

Libraries are only considered if they have both library name and version set. This can be done by setting SOVERSION property with set_target_properties() command.

CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY

在 3.6 版被加入.

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

CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
CPACK_DEBIAN_<COMPONENT>_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:

None

Usage:

set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
    "${CMAKE_CURRENT_SOURCE_DIR}/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")

在 3.4 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA variables.

CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION
CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION

在 3.4 版被加入.

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)

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

備註

The original permissions of the files will be used in the final package unless this variable is set to TRUE. In particular, the scripts should have the proper executable flag prior to the generation of the package.

CPACK_DEBIAN_PACKAGE_SOURCE
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE

在 3.5 版被加入.

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:

See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source

備註

This value is not interpreted. It is possible to pass an optional revision number of the referenced source package as well.

CPACK_DEBIAN_PACKAGE_MULTIARCH
CPACK_DEBIAN_<COMPONENT>_PACKAGE_MULTIARCH

Sets the Multi-Arch field of the Debian package. Packages can declare in their control file how they should handle situations, where packages for different architectures are being installed on the same machine.

Mandatory:

No

Default:

在 3.31 版被加入: Per-component CPACK_DEBIAN_<COMPONENT>_PACKAGE_MULTIARCH variables.

See https://wiki.debian.org/MultiArch/Hints

備註

This value is validated. It must be one of the following values: same, foreign, allowed.

Packaging of debug information

在 3.13 版被加入.

Dbgsym packages contain debug symbols for debugging packaged binaries.

Dbgsym packaging has its own set of variables:

CPACK_DEBIAN_DEBUGINFO_PACKAGE
CPACK_DEBIAN_<component>_DEBUGINFO_PACKAGE

Enable generation of dbgsym .ddeb package(s).

Mandatory:

No

Default:

OFF

備註

Setting this also strips the ELF files in the generated non-dbgsym package, which results in debuginfo only being available in the dbgsym package.

備註

Binaries must contain debug symbols before packaging so use either Debug or RelWithDebInfo for CMAKE_BUILD_TYPE variable value.

Additionally, if CPACK_STRIP_FILES is set, the files will be stripped before they get to the DEB generator, so will not contain debug symbols and a dbgsym package will not get built. Do not use with CPACK_STRIP_FILES.

Building Debian packages on Windows

在 3.10 版被加入.

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

在 3.13 版被加入.

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.
