无论如何要弄清楚没有直接包含哪些STL头文件? [英] Is there anyway to figure out what STL header file has not been included directly?

问题描述

我们的产品使用 C++ 作为编程语言.使用 C++ STL 的一个恼人的问题是我们忘记包含必要的头文件，因为该文件可能已经包含在其他一些 STL 头文件中，构建通过.例如，

Our product uses C++ as the programming language. One annoying issue of using C++ STL is that we forget to include the necessary header files, because the file may have been included in some other STL header, the build passes. For example,

在使用 Xcode 的 Mac 平台中，如果我使用 std::auto_ptr 不包含 memory.h 但包含 iostream.h，构建会通过，但在Android平台上会失败.

In Mac platform using Xcode, if I use std::auto_ptr without include memory.h but include iostream.h, the build will pass, but it will fail in Android platform.

但我不想将代码移动到 Android 以对每个代码更改提交进行构建检查.那么，有没有办法避免这个问题?

But I don't want move the code to Android for an build check for each code change commit. So, is there anyway to avoid that problem?

我知道最好的解决方案是不要忘记包含标题.但是开发人员会犯错.那么有没有什么工具可以帮助检查呢?

Edit 1: I know the best solution is to not forget the include the header. But developers make mistakes. So is there any tool to help check it?

接缝没有理想的解决方案，所以我将使用 vim 脚本在我的编辑器中检查它，解决方案类似于 https://github.com/vim-scripts/vim-cpp-auto-include/blob/master/ftplugin/cpp_auto_include.vim

Edit 2: Seams no ideal solution, so I will use vim script to check it in my editor,the solution is similar to https://github.com/vim-scripts/vim-cpp-auto-include/blob/master/ftplugin/cpp_auto_include.vim

推荐答案

我所知道的唯一工具......就是编译器本身.

The only tool I know of... is the compiler itself.

每当问题是可移植性时，我见过的最佳解决方案就是简单地为所有必需的环境安装自动构建/测试套件.然后，无论何时发出拉取请求，它都会在您的所有构建机器人上进行验证，如果您忘记了某些内容，您将收到警告.

Whenever the issue is portability, the best solution I have seen was to simply put on automated build/test suites for all required environments. Then, whenever a pull request is made it will be validated on all your build bots, and you will be warned if you forgot something.
