为什么Cmake＆＃x2B;包括您使用的内容不打印任何输出？

Question

我已经安装了您使用的内容。 我克隆了存储库，检查了标签0.18并编译了。

$ include-what-you-use -v
clang version 14.0.0 (Fedora 14.0.0-1.fc36)
Target: x86_64-redhat-linux-gnu
Thread model: posix
InstalledDir: /usr/local/bin
Found candidate GCC installation: /usr/lib/gcc/x86_64-redhat-linux/12
Selected GCC installation: /usr/lib/gcc/x86_64-redhat-linux/12
Candidate multilib: .;@m64
Candidate multilib: 32;@m32
Selected multilib: .;@m64
error: unable to handle compilation, expected exactly one compiler job in ''

我将该工具集成到cmake中：

find_program(iwyu_path NAMES include-what-you-use iwyu)
if(iwyu_path)
    message("Found iwyu")
    set(CMAKE_CXX_INCLUDE_WHAT_YOU_USE ${iwyu_path})
endif()

我运行cmake：

$ CC="clang" CXX="clang++" cmake -DCMAKE_CXX_INCLUDE_WHAT_YOU_USE=include-what-you-use ..
-- The CXX compiler identification is Clang 14.0.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/clang++ - skipped
-- Detecting CXX compile features
-- Detecting CXX compile features - done
Found iwyu
-- Configuring done
-- Generating done
-- Build files have been written to: /home/...

并编译：make，但是我在终端中没有看到任何IWYU输出。 为什么这样？

制造的输出：

[steddy@nowhere build]$ CC="clang" CXX="clang++" cmake -DCMAKE_CXX_INCLUDE_WHAT_YOU_USE=include-what-you-use ..

Answer 1

cmake 调用includ-what-you-use 它忽略了任何错误返回代码，只有打印包含的输出才能删除...或应添加...。因此，如果有任何运行的错误包括 - 您使用，它根本没有打印。

您可能可以通过运行运行来诊断错误，并使用冗长 make 中的编译选项手动诊断错误。
