Win API系列 - 编译AWS C ++ SDK [英] Win API Family - Compiling AWS C++ SDK

问题描述

我目前正在尝试在Win32应用程序中使用AWS C ++ SDK作为Pi3B。由于链接器错误而导致ARM编译问题，因为头文件忽略了基于WINAPI_FAMILY的代码。

I am currently trying to use the AWS C++ SDK in a Win32 application for a Pi3B. I am having an issue compiling for ARM due to linker errors with header files that are omitting code based on WINAPI_FAMILY.

正在使用.\vcpkg install aws -sdk-构建AWS项目。 cpp：arm-uwp，这将声明WINAPI_FAMILY = WINAPI_FAMILY_APP作为其构建命令行的一部分。

The AWS project is being built using .\vcpkg install aws-sdk-cpp:arm-uwp and this declares WINAPI_FAMILY=WINAPI_FAMILY_APP as part of its build command line.

但是，除非满足以下条件，否则诸如winhttp.h之类的头文件是不可用的：

However header files such as winhttp.h are not useable unless the following is true:

#if WINAPI_FAMILY_PARTITION（WINAPI_PARTITION_DESKTOP | WINAPI_PARTITION_SYSTEM）

#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_DESKTOP | WINAPI_PARTITION_SYSTEM)

从我所看到的，下面的API在onecoreuap.lib中的Win10 IoT上受支持，事实上我可以从我自己的应用程序访问它。

From what I can see the API beneath the above is supported on Win10 IoT in onecoreuap.lib, in fact I can access it from my own app.

查看winapifamily.h使用WINAPI_FAMILY_APP构建的应用程序不会设置WINAPI_PARTITION_DESKTOP | WINAPI_PARTITION_SYSTEM，因此排除标题的内容，导致链接问题。

Looking at winapifamily.h an app built with WINAPI_FAMILY_APP will not set WINAPI_PARTITION_DESKTOP | WINAPI_PARTITION_SYSTEM and so exclude the contents of the header, causing the link issues.

vcpkg构建是否应指定除WINAPI_FAMILY_APP之外的其他内容，以便能够使用winhttp.h，userenv.h等。？

Should the vcpkg build be specifying something other than WINAPI_FAMILY_APP to be able to use winhttp.h, userenv.h etc.?

谢谢，Mark

推荐答案

除此之外，

在我的C ++控制台应用程序中，使用IoT模板，似乎WINAPI_FAMILY解析为WINAPI_FAMILY_DESKTOP_APP，然后解析为WINAPI_PARTITION_DESKTOP = true，因此头文件包含API。

In my C++ Console App, using the IoT template, it seems that WINAPI_FAMILY resolves to WINAPI_FAMILY_DESKTOP_APP, which then resolves to WINAPI_PARTITION_DESKTOP = true, so the header files include the API.

对于aws构建，WINAPI_FAMILY被设置为WINAPI_FAMILY_APP，重新定义为WINAPI_FAMILY_PC_APP，然后不解析为WINAPI_PARTITION_DESKTOP或WINAPI_PARTITION_SYSTEM。

For the aws build WINAPI_FAMILY is being set to WINAPI_FAMILY_APP, which is redefined as WINAPI_FAMILY_PC_APP which then does not resolve to WINAPI_PARTITION_DESKTOP or WINAPI_PARTITION_SYSTEM.

所以我猜vcpkg构建可能指定了错误姓氏？

So I guess the vcpkg build may be specifying the wrong family name?
