使用 QT 5.12.3 从源代码构建 vlc-qt 时出错

Question

我正在尝试使用 QT5.12.3 从源代码构建 vlc-qt （需要这个特定版本）

我尝试与 ninja 和 mingw makefile 一起使用，我得到了这些错误，并且我尝试了超过 10 个其他 vlc sdk 版本

源：

1. vlc-qt 1.1.1 和 1.2.0 - https://github.com/bibiparrot/vlc-qt
2. vlc 3.0.16 - http://download.videolan.org/pub/videolan/vlc/last/win64/
3. qt 5.12.3 - https://download.qt.io/official_releases/qt/5.12/5.12 .3/

Answer 1

好的，感谢 @vre 我明白了。

解决办法：

1. 下载vlc-qt和vlc 3.0.16并解压。
2. 打开 cmake-gui 选择您的 Visual Studio 并选中“指定本机编译器”。
   
3. 将编译器设置为正确的 MSVC，如图所示
   
4. 添加条目..或者只需单击“配置”并如图所示填写
   
5. 填写完所有条目并且没有错误后，单击“生成”
6. 单击“打开项目”以通过 Visual Studio 和 Build 打开它。
