vs2017中的MFC开发 [英] MFC development in vs2017

问题描述

安装vs2017时，确实选择了带有C ++选项的Windows开发.但是，安装后，我看不到已添加MFC.果然，在编译应用程序时出现错误，

严重错误C1083:无法打开包含文件:'afxwin.h':没有此类文件或目录

我在控制面板中的vs2017安装中找不到更改/修改"选项.如何添加用于C ++的Microsoft基础类"软件包?

解决方案

如果您在VS Installer窗口顶部附近查看，则会看到Workloads，Individual Components和Language Packs.

至少据我所知，工作负载"中没有一个将MFC包含在您的安装中.要获得它，您首先必须单击单个组件"，然后向下滚动相当的方式以转到"SDK，库和框架"部分.在其中，您将找到用于ATL和MFC支持的组件的列表:

在VS 2019安装程序中，可能性列表甚至更长.对于141和142个构建集，都有适用于ARM，ARM64和x86/x64的版本，带有和不带有Spectre缓解措施:

但这并不一定就是故事的结局:默认情况下，即使您安装了它，它也只会安装MFC的Unicode版本.如果要使用窄字符版本，则必须单独安装.我认为安装程序中根本没有任何条目可以执行此操作-但是，如果您尝试构建使用窄字符MFC的项目，则会收到一条错误消息，其中包含下载它的链接.

When I installed vs2017, I did select Windows development with C++ option. After installation, however, I don't see the MFC has been added. Sure enough, I get errors when I compile my application,

fatal error C1083: Cannot open include file: 'afxwin.h': No such file or directory

I cannot find the Change/Modify option with my vs2017 installation in Control Panel. How can I add "Microsoft Foundation Classes for C++" package?

解决方案

If you look near the top of the VS Installer window, you'll see Workloads, Individual Components and Language Packs.

At least as far as I can see, none of the "Workloads" will include MFC in your installation. To get it, you first have to click on "Individual Components", then scroll quite a ways down to get to the "SDKs, libraries and frameworks" section. In there, you'll find a list of components for ATL and MFC support:

In the VS 2019 installer, the list of possibilities has gotten even longer. There are versions for ARM, ARM64, and x86/x64 both with and without Spectre mitigations, for each of the 141 and 142 build sets:

That's not necessarily the end of the story though: by default, even when you install that, it only installs the version Unicode build of MFC. If you want the narrow-character version, you have to install that separately. I don't think there's any entry in the installer to do this at all--but if you try to build a project that uses narrow-character MFC, you'll get an error message that includes a link to download it.
