cppcheck: error: unrecognized command line option: "--file-filter

Question

我正在 Ubuntu 20.04 上开发 C 代码。

来自 运行 cppcheck -q --project=build/proj1/compile_commands.json --file-filter='src/base/Myfile.c'

我收到错误消息

cppcheck: error: unrecognized command line option: "--file-filter=src/base/Myfile.c".

Answer 1

看来Ubuntu20.04中包含的cppcheck版本不是最新的：

$ apt show cppcheck | grep Version
Version: 1.90-4build1

cppcheck 1.90 于 2019 年发布。--file-filter 参数在 2020 年提交 fcd5cda97 中引入：

$ git show fcd5cda97f10085c7def7fda6fc6199f624010ce
