使用VS2015链接静态库 [英] Linking against static lib with VS2015

问题描述

我使用的是使用2015工具集构建的静态库，使用2017构建我的DLL。在该配置中 - 并希望支持 - 我收到链接器错误，指出它无法找到从静态lib导出的符号，我正在联系。当我使用2015工具集切换到
构建我的DLL时，这对我来说似乎是明显的补救措施，我从链接器中得到以下错误：

LINK：致命错误C1007 ：'p2'中无法识别的标志'-Ot'

当我在VS中查看项目属性页中的命令行时，我找不到任何我传入的内容。 / p>

在线阅读文档，似乎我应该能够将2017工具集与使用2015工具集创建的静态库链接。那是对的吗？如果没有，我如何摆脱无法识别的标志错误？

谢谢，

"Ot"可能是一种优化，看看这个。

有人修复了此错误，对不起尝试将Visual Studio更新到最新版本？

I am using a static lib built with the 2015 toolset, building my DLL using 2017. In that configuration - and hoping that is supported - I get linker errors stating it can't find symbols exported from the static lib, I am linking against. When I switch to building my DLL using the 2015 toolset, which seemed like the obvious remedy to me, I get the following error from the linker:

LINK: fatal error C1007: unrecognized flag '-Ot' in 'p2'

I don't find anywhere I pass in -Ot when I look at the commandline in the property pages of the project in VS.

Reading the docs online, it seems that I should be able to link with the 2017 toolset against a static lib created with the 2015 toolset. Is that correct? If not, how do I get rid of that unrecognized flag error?

Thanks,

The "Ot" may be a kind of Optimization, look at this.

Someone had fixed this error, have you tried updating Visual Studio to the latest version?
