交叉编译壁炉靶向窗户

Cross compiling firebreath targeting windows

由于NPAPI使用编译的二进制文件几乎100％，因此希望同时构建包含所有平台代码的插件，因此，交叉汇编成为构建系统的优先级是有意义的NPAPI框架。但是，当我尝试跨越Mac OS X的窗户越过Firebreath Targether时，我会得到：

有没有办法绕过？

无法跨编译Windows libs，因为ActiveX代码当前需要ATL的简单原因，这只能通过Visual Studio构建（据我所知）。我建议您为Windows Builds设有构建机器运行窗口并使用Visual Studio（理想情况下是专业的，但可能与Express可行）。

问题可能是可以解决的，但这将是一项巨大的工作 - 到目前为止，没有人花时间去做这项工作。

交叉兼容会很好，但这肯定不是Firebreath团队（我是主要开发人员）的优先事项，因为在Windows上构建这是一个简单的事情。就我个人而言，我使用詹金斯（Jenkins）在所有平台上同时建立作业并收集工件。从成本角度来看，这比消除ATL依赖性所需的便宜得多。

也就

作为旁注，我从未添加过仅在Windows上构建NPAPI版本的功能，从理论上讲，该版本不需要ATL，因为仍然有几个部分，例如DllRegisterserver功能，它们依靠ATL。不过，补充功能会更容易，并且只需要您提出一个不错的抽象来替换所有功能，然后有条件地排除文件的ActiveX部分；这不是一个简单的任务，而是比没有ATL的整个COM堆栈更容易的数量级。
