【问题描述】：
我正在尝试从我的 lcov 跟踪文件中删除某些目录，但没有任何成功。我正在尝试使用相对路径，并且正在使用 cygwin。我的测试框架是cpputest。
我的目录结构是这样的
foo_library
$ tree
├── bar
│ ├── bar.c
│ ├── bar.h
│ ├── bar.o
│ └── makefile
├── makefile
├── readme.md
├── foo.c
├── foo.h
├── foo.o
├── baz
│ ├── baz.c
│ └── baz.h
└── test
├── AllTests.cpp
├── bar
│ ├── bar.d
│ ├── bar.gcda
│ ├── bar.gcno
│ └── bar.o
├── lcov.info
├── lcov-filtered.info
├── Makefile
├── foo.d
├── foo.gcno
├── foo.o
├── baz
│ ├── baz.d
│ ├── baz.gcda
│ ├── baz.gcno
│ └── baz.o
├── test_foo.cpp
├── test-lib
│ └── libfoo.a
├── test-obj
│ ├── AllTests.d
│ ├── AllTests.gcda
│ ├── AllTests.gcno
│ ├── AllTests.o
│ ├── test_foo.d
│ ├── test_foo.gcda
│ ├── test_foo.gcno
│ ├── test_foo.o
│ ├── wrap_foo.d
│ ├── wrap_foo.gcda
│ ├── wrap_foo.gcno
│ └── wrap_foo.o
├── foo_tests.exe
├── wrap_foo.c
└── wrap_foo.h
这是一个例子

最终我只想生成这个 foo.c 文件的覆盖率数据，我想排除或删除其他所有内容。
我尝试过使用这些目录的绝对路径，例如'cygdrive/C/Work/git/foo_library/test/bar/*'，我也尝试过
'`pwd`/test/bar/*'
我也不确定我应该指定哪些路径、gcda 文件的路径或源文件的路径。我都试过了。
我也尝试在我的捕获和删除命令中使用 -b . 和 -b ../。
编辑： 我必须从 test 子目录运行它才能确定路径。以下显示了完整路径
nick test

编辑：
如果我这样做：$ lcov -r lcov.info '*bar*' '*baz*' '*cpp' -o lcov-filtered.info
它做我想要的。但是，这似乎有点沉重。
