MSVC debug information format flags are selected by an abstraction.
|
||
|
|
|
||
|
|
Compilers targeting the MSVC ABI have flags to select the debug information
|
||
|
|
format. Debug information format selection typically varies with build
|
||
|
|
configuration.
|
||
|
|
|
||
|
|
In CMake 3.24 and below, debug information format flags are added to
|
||
|
|
the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache entries by CMake
|
||
|
|
automatically. This allows users to edit their cache entries to adjust the
|
||
|
|
flags. However, the presence of such default flags is problematic for
|
||
|
|
projects that want to choose a different runtime library programmatically.
|
||
|
|
In particular, it requires string editing of the
|
||
|
|
:variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` variables with knowledge of the
|
||
|
|
CMake builtin defaults so they can be replaced.
|
||
|
|
|
||
|
|
CMake 3.25 and above prefer to leave the debug information format flags
|
||
|
|
out of the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` values and instead
|
||
|
|
offer a first-class abstraction. The
|
||
|
|
:variable:`CMAKE_MSVC_DEBUG_INFORMATION_FORMAT` variable and
|
||
|
|
:prop_tgt:`MSVC_DEBUG_INFORMATION_FORMAT` target property may be set to
|
||
|
|
select the MSVC debug information format. If they are not set, CMake
|
||
|
|
enables debug information in debug configurations using the default value
|
||
|
|
``$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>``, if supported by the
|
||
|
|
compiler, and otherwise ``$<$<CONFIG:Debug,RelWithDebInfo>:Embedded>``.
|
||
|
|
|
||
|
|
This policy provides compatibility with projects that have not been updated
|
||
|
|
to be aware of the abstraction. The policy setting takes effect as of the
|
||
|
|
first :command:`project` or :command:`enable_language` command that enables
|
||
|
|
a language whose compiler targets the MSVC ABI.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
Once the policy has taken effect at the top of a project, that choice
|
||
|
|
will be used throughout the tree. In projects that have nested projects
|
||
|
|
in subdirectories, be sure to confirm if everything is working with the
|
||
|
|
selected policy behavior.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to place MSVC debug information
|
||
|
|
format flags in the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache
|
||
|
|
entries and ignore the :variable:`CMAKE_MSVC_DEBUG_INFORMATION_FORMAT`
|
||
|
|
abstraction. The ``NEW`` behavior for this policy is to *not* place MSVC
|
||
|
|
debug information format flags in the default cache entries and use
|
||
|
|
the abstraction instead.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.25. Use the
|
||
|
|
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
|
||
|
|
Unlike many policies, CMake version |release| does *not* warn
|
||
|
|
when this policy is not set and simply uses ``OLD`` behavior.
