CPackRPM

The built in (binary) CPack RPM generator (Unix only)

Variables specific to CPack RPM generator

CPackRPM may be used to create RPM packages using CPack. CPackRPM is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

CPackRPM has specific features which are controlled by the specifics CPACK_RPM_XXX variables.

CPACK_RPM_<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. Usually those variables correspond to RPM spec file entities. One may find information about spec files here http://www.rpm.org/wiki/Docs

Note

<COMPONENT> part of variables is preferred to be in upper case (for e.g. if component is named foo then use CPACK_RPM_FOO_XXXX variable name format) as is with other CPACK_<COMPONENT>_XXXX variables. For the purposes of back compatibility (CMake/CPack version 3.5 and lower) support for same cased component (e.g. fOo would be used as CPACK_RPM_fOo_XXXX) is still supported for variables defined in older versions of CMake/CPack but is not guaranteed for variables that will be added in the future. For the sake of back compatibility same cased component variables also override upper cased versions where both are present.

Here are some CPackRPM wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:

• https://cmake.org/Wiki/CMake:CPackConfiguration

• https://cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

List of CPackRPM specific variables:

CPACK_RPM_COMPONENT_INSTALL

Enable component packaging for CPackRPM

• Mandatory : NO

• Default : OFF

If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.

CPACK_RPM_PACKAGE_SUMMARY

CPACK_RPM_<component>_PACKAGE_SUMMARY

The RPM package summary.

• Mandatory : YES

• Default : CPACK_PACKAGE_DESCRIPTION_SUMMARY

CPACK_RPM_PACKAGE_NAME

CPACK_RPM_<component>_PACKAGE_NAME

The RPM package name.

• Mandatory : YES

• Default : CPACK_PACKAGE_NAME

CPACK_RPM_FILE_NAME

CPACK_RPM_<component>_FILE_NAME

Package file name.

• Mandatory : YES

• Default<CPACK_PACKAGE_FILE_NAME>[-<component>].rpm with spaces

  replaced by ‘-‘

This may be set to RPM-DEFAULT to allow rpmbuild tool to generate package file name by itself. Alternatively provided package file name must end with .rpm suffix.

Note

By using user provided spec file, rpm macro extensions such as for generating debuginfo packages or by simply using multiple components more than one rpm file may be generated, either from a single spec file or from multiple spec files (each component execution produces it’s own spec file). In such cases duplicate file names may occur as a result of this variable setting or spec file content structure. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.

CPACK_RPM_MAIN_COMPONENT

Main component that is packaged without component suffix.

• Mandatory : NO

• Default : -

This variable can be set to any component or group name so that component or group rpm package is generated without component suffix in filename and package name.

CPACK_RPM_PACKAGE_VERSION

The RPM package version.

• Mandatory : YES

• Default : CPACK_PACKAGE_VERSION

CPACK_RPM_PACKAGE_ARCHITECTURE

CPACK_RPM_<component>_PACKAGE_ARCHITECTURE

The RPM package architecture.

• Mandatory : YES

• Default : Native architecture output by uname -m

This may be set to noarch if you know you are building a noarch package.

CPACK_RPM_PACKAGE_RELEASE

The RPM package release.

• Mandatory : YES

• Default : 1

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

Note

This is the string that goes into the RPM Release: field. Some distros (e.g. Fedora, CentOS) require 1%{?dist} format and not just a number. %{?dist} part can be added by setting CPACK_RPM_PACKAGE_RELEASE_DIST.

CPACK_RPM_PACKAGE_RELEASE_DIST

The dist tag that is added RPM Release: field.

• Mandatory : NO

• Default : OFF

This is the reported %{dist} tag from the current distribution or empty %{dist} if RPM macro is not set. If this variable is set then RPM Release: field value is set to ${CPACK_RPM_PACKAGE_RELEASE}%{?dist}.

Possible values are:

• lzma

• xz

• bzip2

• gzip

CPACK_RPM_PACKAGE_AUTOREQ

CPACK_RPM_<component>_PACKAGE_AUTOREQ

RPM spec autoreq field.

If this variable is set to TRUE or ON CPackRPM will try to build a relocatable RPM package. A relocatable RPM may be installed using:

rpm --prefix or --relocate

in order to install it at an alternate place see rpm(8). Note that currently this may fail if CPACK_SET_DESTDIR is set to ON. If CPACK_SET_DESTDIR is set then you will get a warning message but if there is file installed with absolute path you’ll get unexpected behavior.

CPACK_RPM_SPEC_INSTALL_POST

Deprecated - use CPACK_RPM_POST_INSTALL_SCRIPT_FILE instead.

• Mandatory : NO

• Default : -

• Deprecated: YES

This way of specifying post-install script is deprecated, use CPACK_RPM_POST_INSTALL_SCRIPT_FILE. May be used to set an RPM post-install command inside the spec file. For example setting it to /bin/true may be used to prevent rpmbuild to strip binaries.

CPACK_RPM_SPEC_MORE_DEFINE

RPM extended spec definitions lines.

• Mandatory : NO

• Default : -

May be used to add any %define lines to the generated spec file.

CPACK_RPM_PACKAGE_DEBUG

Toggle CPackRPM debug output.

• Mandatory : NO

• Default : -

May be set when invoking cpack in order to trace debug information during CPack RPM run. For example you may launch CPack like this:

cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM

CPACK_RPM_USER_BINARY_SPECFILE

CPACK_RPM_<componentName>_USER_BINARY_SPECFILE

A user provided spec file.

• Mandatory : NO

• Default : -

May be set by the user in order to specify a USER binary spec file to be used by CPackRPM instead of generating the file. The specified file will be processed by configure_file( @ONLY).

CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE

Spec file template.

• Mandatory : NO

• Default : -

If set CPack will generate a template for USER specified binary spec file and stop with an error. For example launch CPack like this:

cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM

The user may then use this file in order to hand-craft is own binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.

CPACK_RPM_PRE_INSTALL_SCRIPT_FILE

CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE

Path to file containing pre (un)install script.

• Mandatory : NO

• Default : -

May be used to embed a pre (un)installation script in the spec file. The referred script file (or both) will be read and directly put after the %pre or %preun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each component can be overridden with CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE. One may verify which scriptlet has been included with:

rpm -qp --scripts  package.rpm

CPACK_RPM_POST_INSTALL_SCRIPT_FILE

CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE

Path to file containing post (un)install script.

• Mandatory : NO

• Default : -

May be used to embed a post (un)installation script in the spec file. The referred script file (or both) will be read and directly put after the %post or %postun section. If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each component can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE. One may verify which scriptlet has been included with:

rpm -qp --scripts  package.rpm

CPACK_RPM_USER_FILELIST

CPACK_RPM_<COMPONENT>_USER_FILELIST

• Mandatory : NO

• Default : -

May be used to explicitly specify %(<directive>) file line in the spec file. Like %config(noreplace) or any other directive that be found in the %files section. You can have multiple directives per line, as in %attr(600,root,root) %config(noreplace). Since CPackRPM is generating the list of files (and directories) the user specified files of the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list. If referring to directories do not add a trailing slash.

CPACK_RPM_CHANGELOG_FILE

RPM changelog file.

• Mandatory : NO

• Default : -

May be used to embed a changelog in the spec file. The referred file will be read and directly put after the %changelog section.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST

list of path to be excluded.

• Mandatory : NO

• Default : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include

May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The defaut value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then CPackRPM will NOT any of the default path. If you want to add some path to the default list then you can use CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION

additional list of path to be excluded.

• Mandatory : NO

• Default : -

May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.

CPACK_RPM_RELOCATION_PATHS

Packages relocation paths list.

• Mandatory : NO

• Default : -

May be used to specify more than one relocation path per relocatable RPM. Variable contains a list of relocation paths that if relative are prefixed by the value of CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX or by the value of CPACK_PACKAGING_INSTALL_PREFIX if the component version is not provided. Variable is not component based as its content can be used to set a different path prefix for e.g. binary dir and documentation dir at the same time. Only prefixes that are required by a certain component are added to that component - component must contain at least one file/directory/symbolic link with CPACK_RPM_RELOCATION_PATHS prefix for a certain relocation path to be added. Package will not contain any relocation paths if there are no files/directories/symbolic links on any of the provided prefix locations. Packages that either do not contain any relocation paths or contain files/directories/symbolic links that are outside relocation paths print out an AUTHOR_WARNING that RPM will be partially relocatable.

CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX

Per component relocation path install prefix.

• Mandatory : NO

• Default : CPACK_PACKAGING_INSTALL_PREFIX

May be used to set per component CPACK_PACKAGING_INSTALL_PREFIX for relocatable RPM packages.

CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION

CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION

Removal of default install prefix from relocation paths list.

• Mandatory : NO

• DefaultCPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX

  are treated as one of relocation paths

May be used to remove CPACK_PACKAGING_INSTALL_PREFIX and CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX from relocatable RPM prefix paths.

CPACK_RPM_ADDITIONAL_MAN_DIRS

• Mandatory : NO

• Default : -

May be used to set additional man dirs that could potentially be compressed by brp-compress RPM macro. Variable content must be a list of regular expressions that point to directories containing man files or to man files directly. Note that in order to compress man pages a path must also be present in brp-compress RPM script and that brp-compress script must be added to RPM configuration by the operating system.

Regular expressions that are added by default were taken from brp-compress RPM macro:

• /usr/man/man.*

• /usr/man/.*/man.*

• /usr/info.*

• /usr/share/man/man.*

• /usr/share/man/.*/man.*

• /usr/share/info.*

• /usr/kerberos/man.*

• /usr/X11R6/man/man.*

• /usr/lib/perl5/man/man.*

• /usr/share/doc/.*/man/man.*

• /usr/lib/.*/man/man.*

CPACK_RPM_DEFAULT_USER

CPACK_RPM_<compName>_DEFAULT_USER

default user ownership of RPM content

• Mandatory : NO

• Default : root

Value should be user name and not UID. Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_GROUP

CPACK_RPM_<compName>_DEFAULT_GROUP

default group ownership of RPM content

• Mandatory : NO

• Default : root

Value should be group name and not GID. Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_FILE_PERMISSIONS

CPACK_RPM_<compName>_DEFAULT_FILE_PERMISSIONS

default permissions used for packaged files

• Mandatory : NO

• Default : - (system default)

Accepted values are lists with PERMISSIONS. Valid permissions are:

• OWNER_READ

• OWNER_WRITE

• OWNER_EXECUTE

• GROUP_READ

• GROUP_WRITE

• GROUP_EXECUTE

• WORLD_READ

• WORLD_WRITE

• WORLD_EXECUTE

Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_DIR_PERMISSIONS

CPACK_RPM_<compName>_DEFAULT_DIR_PERMISSIONS

default permissions used for packaged directories

• Mandatory : NO

• Default : - (system default)

Accepted values are lists with PERMISSIONS. Valid permissions are the same as for CPACK_RPM_DEFAULT_FILE_PERMISSIONS. Note that <compName> must be in upper-case.

Packaging of Symbolic Links

CPackRPM supports packaging of symbolic links:

execute_process(COMMAND ${CMAKE_COMMAND}
  -E create_symlink <relative_path_location> <symlink_name>)
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
  DESTINATION <symlink_location> COMPONENT libraries)

Symbolic links will be optimized (paths will be shortened if possible) before being added to the package or if multiple relocation paths are detected, a post install symlink relocation script will be generated.

Symbolic links may point to locations that are not packaged by the same package (either a different component or even not packaged at all) but those locations will be treated as if they were a part of the package while determining if symlink should be either created or present in a post install script - depending on relocation paths.

Symbolic links that point to locations outside packaging path produce a warning and are treated as non relocatable permanent symbolic links.

Currently there are a few limitations though:

• For component based packaging component interdependency is not checked when processing symbolic links. Symbolic links pointing to content of a different component are treated the same way as if pointing to location that will not be packaged.

• Symbolic links pointing to a location through one or more intermediate symbolic links will not be handled differently - if the intermediate symbolic link(s) is also on a relocatable path, relocating it during package installation may cause initial symbolic link to point to an invalid location.

Packaging of debug information

Debuginfo packages contain debug symbols and sources for debugging packaged binaries.

Debuginfo RPM packaging has it’s own set of variables:

CPACK_RPM_DEBUGINFO_PACKAGE

CPACK_RPM_<component>_DEBUGINFO_PACKAGE

Enable generation of debuginfo RPM package(s).

• Mandatory : NO

• Default : OFF

Note

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

Note

Packages generated from packages without binary files, with binary files but without execute permissions or without debug symbols will be empty.

CPACK_BUILD_SOURCE_DIRS

Provides locations of root directories of source files from which binaries were built.

• Mandatory : YES if CPACK_RPM_DEBUGINFO_PACKAGE is set

• Default : -

Note

For CMake project CPACK_BUILD_SOURCE_DIRS is set by default to point to CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR paths.

Note

Sources with path prefixes that do not fall under any location provided with CPACK_BUILD_SOURCE_DIRS will not be present in debuginfo package.

CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX

CPACK_RPM_<component>_BUILD_SOURCE_DIRS_PREFIX

Prefix of location where sources will be placed during package installation.

• Mandatory : YES if CPACK_RPM_DEBUGINFO_PACKAGE is set

• Default“/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>” and

  for component packaging “/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>-<component>”

Note

Each source path prefix is additionaly suffixed by src_<index> where index is index of the path used from CPACK_BUILD_SOURCE_DIRS variable. This produces <CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX>/src_<index> replacement path. Limitation is that replaced path part must be shorter or of equal length than the length of its replacement. If that is not the case either CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX variable has to be set to a shorter path or source directories must be placed on a longer path.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS

Directories containing sources that should be excluded from debuginfo packages.

• Mandatory : NO

• Default : “/usr /usr/src /usr/src/debug”

Listed paths are owned by other RPM packages and should therefore not be deleted on debuginfo package uninstallation.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS_ADDITION

Paths that should be appended to CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS for exclusion.

• Mandatory : NO

• Default : -

CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE

Create a single debuginfo package even if components packaging is set.

• Mandatory : NO

• Default : OFF

When this variable is enabled it produces a single debuginfo package even if component packaging is enabled.

When using this feature in combination with components packaging and there is more than one component this variable requires CPACK_RPM_MAIN_COMPONENT to be set.

Note

If none of the CPACK_RPM_<component>_DEBUGINFO_PACKAGE variables is set then CPACK_RPM_DEBUGINFO_PACKAGE is automatically set to ON when CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE is set.

Packaging of sources (SRPM)

SRPM packaging is enabled by setting CPACK_RPM_PACKAGE_SOURCES variable while usually using CPACK_INSTALLED_DIRECTORIES variable to provide directory containing CMakeLists.txt and source files.

For CMake projects SRPM package would be product by executing:

cpack -G RPM --config ./CPackSourceConfig.cmake

Note

Produced SRPM package is expected to be built with cmake(1) executable and packaged with cpack(1) executable so CMakeLists.txt has to be located in root source directory and must be able to generate binary rpm packages by executing cpack -G command. The two executables as well as rpmbuild must also be present when generating binary rpm packages from the produced SRPM package.

Once the SRPM package is generated it can be used to generate binary packages by creating a directory structure for rpm generation and executing rpmbuild tool:

mkdir -p build_dir/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS} rpmbuild --define "_topdir <path_to_build_dir>" --rebuild <SRPM_file_name>

Generated packages will be located in build_dir/RPMS directory or its sub directories.

Note

SRPM package internally uses CPack/RPM generator to generate binary packages so CMakeScripts.txt can decide during the SRPM to binary rpm generation step what content the package(s) should have as well as how they should be packaged (monolithic or components). CMake can decide this for e.g. by reading environment variables set by the package manager before starting the process of generating binary rpm packages. This way a single SRPM package can be used to produce different binary rpm packages on different platforms depending on the platform’s packaging rules.

Source RPM packaging has it’s own set of variables:

CPACK_RPM_PACKAGE_SOURCES

Should the content be packaged as a source rpm (default is binary rpm).

• Mandatory : NO

• Default : OFF

Note

For cmake projects CPACK_RPM_PACKAGE_SOURCES variable is set to OFF in CPackConfig.cmake and ON in CPackSourceConfig.cmake generated files.

CPACK_RPM_SOURCE_PKG_BUILD_PARAMS

Additional command-line parameters provided to cmake(1) executable.

• Mandatory : NO

• Default : -

CPACK_RPM_SOURCE_PKG_PACKAGING_INSTALL_PREFIX

Packaging install prefix that would be provided in CPACK_PACKAGING_INSTALL_PREFIX variable for producing binary RPM packages.

• Mandatory : YES

• Default : “/”

CPACK_RPM_BUILDREQUIRES

List of source rpm build dependencies.

• Mandatory : NO

• Default : -

May be used to set source RPM build dependencies (BuildRequires). Note that you must enclose the complete build requirements string between quotes, for example:

set(CPACK_RPM_BUILDREQUIRES "python >= 2.5.0, cmake >= 2.8")
