|
| ''add_pc_lint'' is a CMake macro for generating build targets for PC-Lint.
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/contrib/macros/PC-Lint here]. |
| | |
| If you use it, you will get a build target invoking pc-lint for each source file with the same include directories and preprocessor defines as for the compiler. The lint build target will have the same name as your original build target, but with ''_LINT'' appended. You will also get the build target ALL_LINT which invokes all *_LINT targets. The *_LINT targets will not be built with ALL_BUILD. Only if they are directly built or if ALL_LINT is built.
| |
| | |
| This setup integrates PC-Lint into your existing setup. It has been tested with Visual Studio 8 and NMake Makefiles. | |
| | |
| === Usage ===
| |
| | |
| If you want to use this macro, you need:
| |
| | |
| * an existing CMake setup for your project
| |
| * PC-Lint installed
| |
| * configuration files for PC-Lint
| |
| | |
| ==== Synopsis ====
| |
| | |
| add_pc_lint(target source1 [source2 ...])
| |
| | |
| ; target : the name of the target to which the sources belong. You will get a new build target named ${target}_LINT
| |
| | |
| ; source1 source2 ... : a list of source files to be linted. Just pass the same list as you passed for add_executable or add_library. Everything except C and CPP files (*.c, *.cpp, *.cxx) will be filtered out.
| |
| | |
| ==== Example ====
| |
| | |
| If you have a CMakeLists.txt which generates an executable (or library) like this:
| |
| | |
| <pre>
| |
| set(MAIN_SOURCES main.c foo.c bar.c)
| |
| add_executable(main ${MAIN_SOURCES})
| |
| </pre>
| |
| | |
| include this file (only once, preferrably at the top level CMakeLists.txt)
| |
| | |
| <pre>
| |
| include(/path/to/pc_lint.cmake)
| |
| </pre>
| |
| | |
| and add a command to generate the main_LINT target
| |
| | |
| <pre>
| |
| if(COMMAND add_pc_lint)
| |
| add_pc_lint(main ${MAIN_SOURCES})
| |
| endif(COMMAND add_pc_lint)
| |
| </pre>
| |
| | |
| === Configuration ===
| |
| | |
| The pc_lint.cmake script exports the following CMake cache variables, which you have to adjust using the CMake tools to fit your environment.
| |
| | |
| ; PC_LINT_EXECUTABLE : Full path to the pc-lint executable. Not the generated lin.bat. On a standard PC-Lint installation, this path is ''c:/lint/lint-nt.exe''
| |
| | |
| ; PC_LINT_CONFIG_DIR : Full path to the directory containing pc-lint configuration files. For each Platform/Compiler/Toolchain, you may want to have a different set of options. If you keep these options in separate directories, you can point this variable to the appropriate one. ''add_pc_lint'' assumes that there is a file called ''std.lnt'' in the configuration directory which includes all further lint option files.
| |
| | |
| ; PC_LINT_USER_FLAGS : Additional pc-lint command line options. Some flags of pc-lint cannot be set in option files (most notably -b).
| |
| | |

| add_custom_target(ALL_LINT)
| |
| | |
| # add_pc_lint(target source1 [source2 ...])
| |
| #
| |
| # Takes a list of source files and generates a build target which can be used
| |
| # for linting all files
| |
| #
| |
| # The generated lint commands assume that a top-level config file named
| |
| # 'std.lnt' resides in the configuration directory 'PC_LINT_CONFIG_DIR'. This
| |
| # config file must include all other config files. This is standard lint
| |
| # behaviour.
| |
| #
| |
| # Parameters:
| |
| # - target: the name of the target to which the sources belong. You will get a
| |
| # new build target named ${target}_LINT
| |
| # - source1 ... : a list of source files to be linted. Just pass the same list
| |
| # as you passed for add_executable or add_library. Everything except
| |
| # C and CPP files (*.c, *.cpp, *.cxx) will be filtered out.
