Dartium 无法在 windows 上构建

Question

我正在尝试在 windows 上构建 Dartium 版本，但我一直运行遇到问题。

我正在尝试使用专有编解码器构建 Dartium，因此我可以在 MP4 文件中播放 AAC 编解码器，这是普通 Dartium 无法播放的。

我在 windows 2016 数据中心 (VM) 上构建它，我安装了 Dart 32 位，Visual Studio 2015，带有 windows SDK，并按照以下说明操作：https://github.com/dart-lang/sdk/wiki/Building-Dartium

Answer 1

如果你加上

#pragma warning disable C4172

在 thread.cc 的顶部，应该可以修复编译。
