Cppcheck-2.18.0
Release Notes for Cppcheck 2.18
Changed interface:
- Updated path matching syntax for -i, --file-filter, suppressions, GUI excludes, and project file excludes.
Old patterns that use a*may need to use**instead if it is intended to match path separators. More details can be seen in the manual.
Deprecations:
- Support for building with Qt 5 will be removed in Cppcheck 2.19.
- The platform 'unix32-unsigned' has been deprecated and will be removed in Cppcheck 2.19. Please use '--platform=unix32 --funsigned-char' instead.
- The platform 'unix64-unsigned' has been deprecated and will be removed in Cppcheck 2.19. Please use '--platform=unix64 --funsigned-char' instead.
Other:
- Updated Qt to 6.9.1 (official Windows release only).
- added CMake target
run-clang-tidy-csato run Clang Static Analyzer - added CMake option
ENABLE_CSA_ALPHAto enable the Clang Static Analyzer alpha checkers - Updated TinyXML-2 to v11.0.0
- The minimum supported Python version has been bumped to 3.7.
- CMake will now unconditionally use Boost.Containers if available. If CMake option
USE_BOOSTis specified it will now bail out when it is not found. - Fix checking a project that contains several project file entries for the same file.
- Fixed --file-filter matching of looked up files in provided paths.
- Split up cstyleCast checker; dangerous casts produce portability/warning reports, safe casts produce style reports.

Full Changelog: 2.14.0...2.14.1
Cppcheck-2.14.0
Release Notes for Cppcheck 2.14.0
Summary:
- Fixed 23 "crash" tickets
- Fixed 69 "false positive" tickets
- Fixed 36 "improve check" tickets
New checks:
- eraseIteratorOutOfBounds: warns when erase() is called on an iterator that is out of bounds
- returnByReference: warns when a large class member is returned by value from a getter function
GUI:
-Make it possible to suppress warnings in all files in a folder
Changed interface:
- Fixed crash with '--rule-file=' if some data was missing.
- '--rule-file' will now bail out if a rule could not be added or a file contains unexpected data.
- Add option '--check-version', you can use it to pin the cppcheck version in a script.
- Added '--template=simple'. It is expands to '{file}:{line}:{column}: {severity}:{inconclusive:inconclusive:} {message} [{id}]' without any additional location details.
- Removed deprecated platform type 'Unspecified'. Please use 'unspecified' instead.
- Add --file-filter=- option that reads file filters from stdin. Added for a plugin.
Other:
- Added CMake option 'EXTERNALS_AS_SYSTEM' to treat external includes as 'SYSTEM' ones.
- The minimum required compiler versions have been bumped to GCC 5.1 / Clang 3.5 / Visual Studio 2015
- The minimum required CMake version has been bumped to 3.5
- Using Visual Studio with CMake now checks if the CMake version is at least 3.13. This was always required but was not checked explicitly.
- Removed deprecated 'Makefile' option 'SRCDIR'.
- Added CMake option 'DISALLOW_THREAD_EXECUTOR' to control the inclusion of the executor which performs the analysis within a thread of the main process.
- Removed CMake option 'USE_THREADS' in favor of 'DISALLOW_THREAD_EXECUTOR'.
- misra-config will not be treated as a critical error anymore
Safety critical:
- #12440 : Misra violations found but cppcheck exited with 0 even after specifying exit code
Cppcheck-2.13.0
Release Notes for Cppcheck 2.13
New checks:
- passedByValueCallback for functions which take a parameter by value but are used as callbacks (subset of passedByValue)
- returnImplicitInt for C functions without return type (previously reported as a debug message)
- iterateByValue for iterating by value in a range-based for loop when a const reference could be used
Changed interface:
- Final report of active checkers is reported as a normal information message instead.
Deprecations:
- "--showtime=top5" has been deprecated and will be removed in Cppcheck 2.14. Please use --showtime=top5_file or --showtime=top5_summary instead.
- Building with Qt5 has been deprecated (it went EOL in May 2023) and will be removed in a future version - please use Qt6 instead.
Other:
- Windows builds now default to the
nativeplatform instead ofwin32Aorwin64. Please specify it explicitly if you depend on it. - The undocumented and deprecated command-line options
--template &l D93E t;template>and--template-format <template>has been removed. Please use--template=and--template-format=instead. - "--showtime=summary" will now show a single summary at the end instead of showing it after each file when using the thread execution (default on Windows)
- added "--showtime=none" to disable any previously specified showtime report. "--showtime=" without parameter is no longer valid.
- Multiple "--project" options are now prohibited. These would have overlapped each other and lead to unexpected behavior. Please use separate runs with a single "--project" option instead.
- "--project" can also no longer be used in conjunction with additional source files.
- If a addon cannot be found it will bail out immediately instead of continously writing errors and failing the analysis at the end.
- clang-tidy was not invoked when the process-based executor (only available on Linux / default) was used.
- Added CMake option "BUILD_MANPAGE" which adds the "man" target which will build the manpage. This requires xsltproc and the docbook XSLs to be installed.
- Added some library configurations to the official Windows installer.
- Removed some unused Qt DLLs from the official Windows installer.
- Improved inline suppressions:
- You can suppress warnings in a block of code using "-begin" and "-end".
- You can suppress warnings in current file using "-file".
- You can suppress all warnings where macro is used using "-macro"
- Cppcheck will now error out when an option, which requires code which is not compiled in, is being specified. In the past it might have silently ignored it or reported it as unknown.
- Several macros defined by "limits.h"/"climits" will now be generated from the used platform condiguration and passed to the analysis.
- fixed CMake build with UBSAN and GCC
- Files will now be processed in the order as specified via the command-line.
- Added command-line options "--fsigned-char" and "--funsigned-char" to control the signess of the "char" type. This overrides previously specified "--platform" options and is overrides by following ones.
- An error is now reported when the "cppcheck.cfg" is invalid. The CLI version will also exit with a failure in that case.
- Fixed loading of addons from "cppcheck.cfg" in the GUI application.
- Markup files will now be processed after the regular source files when using multiple threads/processes (some issues remain - see Trac #12167 for details).
- Added file name to ValueFlow "--debug" output.
- Fixed build when using "clang-cl" in CMake.
Safety critical:
- #10866 unsafe handling of unconditional #error
- #12071 unsafe suppressions of critical errors
- #12079 missing "misra-config" warning, calling unknown function in condition
Cppcheck-2.12.1
Bug fix:
- Fix problem to import GUI project (#5456 ).
Cppcheck-2.12.0
New checks:
- uselessOverride finds overriding functions that either duplicate code from or delegate back to the base class implementation
- knownPointerToBool finds pointer to bool conversions that are always true or false
Improved checking:
- truncLongCastAssignment and truncLongCastReturn check additional types, including float/double/long double
- duplInheritedMember also reports duplicated member functions
- constParameter*/constVariable* checks find more instances of pointers/references that can be const, e.g. when calling library functions
GUI:
- Show in statistics which checkers have been activated in latest analysis
- Make it more visible if there has been critical errors that caused checkers to be skipped
Changed interface:
- Write how many checkers was activated after a run
- Added --checkers-report that can be used to generate a report in a file that shows what checkers was activated and disabled
Deprecations:
- The qmake build system has been deprecated and will be removed in a future version.
- Command-line option '--template ' is deprecated and will be removed in 2.13 - please use '--template=' instead.
- Command-line option '--template-location ' is deprecated and will be removed in 2.13 - please use '--template-location=' instead.
Other:
- "USE_QT6=On" will no longer fallback to Qt5 when Qt6 is not found.
- When the execution of an addon fails with an exitcode it will now result in an 'internalError' instead of being silently ignored.
- "Win32" configurations have been removed from the bundled Visual Studio solution and projects. You might still be able to build 32-bit binaries using CMake but that is untested and unmaintained.
