CMake中的Cppcheck支持 [英] Cppcheck support in CMake
问题描述
我不是在问各种以一种或另一种方式支持Cppcheck的可用第三方模块。
I am not asking about the various available third-party modules that support Cppcheck in one way or the other.
借助CMake 3.10,CMake似乎已经获得了一些官方Cppcheck支持。参见 CMAKE_< LANG> _CPPCHECK 。
With CMake 3.10, CMake seems to have gained some official Cppcheck support. See CMAKE_<LANG>_CPPCHECK.
不幸的是,如何使用此变量的文档有点稀疏。是否有一个很好的示例说明应该如何在CMake 3.10(或更高版本)中使用Cppcheck?
Unfortunately the documentation how to use this variable is a bit sparse. Is there a good example of how Cppcheck is supposed to be used with CMake 3.10 (or later)?
推荐答案
一个简单示例将是-如果您有 cppcheck
在 PATH
中,并且您没有指定其他参数-通过设置全局 CMAKE_< Lang> _CPPCHECK
变量:
An simple example would be - if you have cppcheck
in your PATH
and you are not specifying additional parameters - the following by setting global CMAKE_<LANG>_CPPCHECK
variable:
cmake_minimum_required(VERSION 3.10)
project(CppCheckTest)
file(
WRITE "main.cpp"
[=[
int main()
{
char a[10];
a[10] = 0;
return 0;
}
]=]
)
set(CMAKE_CXX_CPPCHECK "cppcheck")
add_executable(${PROJECT_NAME} "main.cpp")
要自动扫描的文件进入 cppcheck
命令行。因此,上面的示例给出了以下输出(在Linux系统上为 gcc
和 cppcheck
):
The files to scan are added automatically to the cppcheck
command line. So the above example gives the following output (gcc
and cppcheck
on Linux system):
# make
Scanning dependencies of target CppCheckTest
[ 50%] Building CXX object CMakeFiles/CppCheckTest.dir/main.cpp.o
Checking .../CppCheckTest/main.cpp...
Warning: cppcheck reported diagnostics:
[/mnt/c/temp/StackOverflow/CppCheckTest/main.cpp:4]: (error) Array 'a[10]' accessed at index 10, which is out of bounds.
[100%] Linking CXX executable CppCheckTest
[100%] Built target CppCheckTest
您可以在现有项目中尝试 cppcheck
,只需通过<$ c $设置 CMAKE_CXX_CPPCHECK
变量即可c> cmake 命令行:
You could give cppcheck
a try in an existing project by simply setting the CMAKE_CXX_CPPCHECK
variable via the cmake
command line:
# cmake -DCMAKE_CXX_CPPCHECK:FILEPATH=cppcheck ..
更多日常生活示例可能会为您在<$ c中包含以下代码片段$ c> CMakeList.txt :
A more "daily life" example would probably for you to include something like the following code snippet in your CMakeList.txt
:
find_program(CMAKE_CXX_CPPCHECK NAMES cppcheck)
if (CMAKE_CXX_CPPCHECK)
list(
APPEND CMAKE_CXX_CPPCHECK
"--enable=warning"
"--inconclusive"
"--force"
"--inline-suppr"
"--suppressions-list=${CMAKE_SOURCE_DIR}/CppCheckSuppressions.txt"
)
endif()
引用
- CMake Commit: Add properties to run cppcheck along with the compiler
<LANG>_CPPCHECK
target property
仅当
< LANG>
为C
或CXX
。
指定包含以下内容的; -list: cppcheck
静态分析工具的命令行。 Makefile生成器和Ninja生成器将与编译器一起运行 cppcheck
并报告任何问题。
Specify a ;-list containing a command line for the cppcheck
static analysis tool. The Makefile Generators and the Ninja generator will run cppcheck
along with the compiler and report any problems.
此属性是由 CMAKE_< LANG> _CPPCHECK
变量的值初始化(如果在创建目标时已设置)。
This property is initialized by the value of the CMAKE_<LANG>_CPPCHECK
variable if it is set when a target is created.
