错误C2719：'_Val“：用__declspec形式参数（对齐（'16'））将不会被一致？

问题描述

我试图创建 D3DXMATRIXA16 像这样一个向量：矢量＆lt; D3DXMATRIXA16＆GT;矩阵; 和正在错误：

这是为什么什么呢？

感谢您的帮助！

解决方案

这是一个的的那个的stl ::向量不能正确地包含对齐的数据，如D3DXMATRIXA16。一个海报钉扎的根源的（或至少一的他们）：矢量::调整大小的声明价值传递一致的数据，而不是常引用。有几个解决方法是建议在该线程，最安全的幸福的完全丢弃STL ::矢量的。您可能还需要修复STL头自己，重新编译 - 这实际上可能会更容易比它的声音，但我没有这样做我自己。

该问题已在VS2012RC - 这里有一个链接，相应的连接问题。原来这实际上是一个问题，在C ++标准本身，定格在2008年。

I'm trying to create a vector for D3DXMATRIXA16 like so: vector<D3DXMATRIXA16> matrices; and am getting the error:

Why is that exactly?

Thanks for any help!

解决方案

It is a known issue that stl::vector cannot properly contain aligned data, such as D3DXMATRIXA16. One poster pinned the root cause (or at least, one of them?): the declaration of vector::resize passes the aligned data by value, and not as const reference.Several workarounds were suggested in that thread, the safest being dropping stl::vector altogether. You might also want to fix the stl headers yourself and recompile - this actually may be easier than it sounds, but I haven't done so myself.

EDIT: links are now broken (thanks @David Menard), here's an alternative, more elaborate answer.

The issue is fixed in VS2012RC - here's a link to a corresponding connect issue. Turns out it was actually an issue in the C++ standard itself, fixed in 2008.
