VS 2017中的标头cmath Intellisense错误 [英] header cmath Intellisense errors in VS 2017
问题描述
标题cmath根本不起作用，当我在项目中打开cmath标题文件时，VS Intellisense显示类似the global scope has no "acosf"的错误，并且有数百个.
the header cmath simply doesn't work, when I open the cmath header file in my project, the VS Intellisense shows errors like the global scope has no "acosf", and there are hundreds.
我读了很多主题，但是还没有弄清楚.我已经确认我正在根据一个线程使用sdk 10.0.15063.0，但这是行不通的.
I have read a lot of threads but haven't figured it out. I have confirmed that I am using sdk 10.0.15063.0 according to one thread, but it doesn't work.
任何包含cmath的项目都不起作用，因此它可能与特定的代码无关.我已经尽力了，你们能告诉我如何解决吗?预先感谢！
Any project including cmath doesn't work, so it might has nothing to do specific code. I have tried my best, could you guys tell to how to solve it? Thanks in advance!

推荐答案
谢谢大家，我已经解决了这个问题.这是因为包含目录中不同math.h的冲突.
Thanks guys, I have solved the problem. It is because of the clash of different math.hs in the include directories.
