    这是一个创建于 2186 天前的主题，其中的信息可能已经有所发展或是发生改变。

    楼主主要是想编译 opecv 库在 QT 里面使用，但是编译遇到问题，看过各种帖子还是有问题，敢请大佬指教。配置如下：

    • 平台 win10 64 位
    • QT5.8 32 位(QT Creater4.21 + MinGW5.30 32 位 + Cmake 3.81 64 位)
    • Cmake 选项按参考的这篇博客

    使用 QT 编译之后编译到 95%的时候链接出现问题如下：

    ...

    后面问题都先不管了，但是最前面的 undefined reference to '__mingw_vfscanf'以及 undefined reference to '__ms_vsnprintf'这类问题不知道什么原因。查了资料之后发现有类似的一个帖子说是编译工具链的问题,但是除了 cmake 其他的都是 QT 内置的啊。大佬请赐教。

    换个版本试试。有时就是很玄学。我的 cmake3.11.1 编 Opencv320 没出错。

    @EvanG 老哥你的 Cmake 是 64 位的么，会不会是 camke 需要 32 位的啊==

    opencv 直接就可以在 Qt 里面用啊，为什么要自己编译

    @Justkkk 编译 OPenCV 的库啊，动态库 静态库啥，安装好的之后 win64 位的可以直接用 32 位的不行

    @GhostRider 你就想编译一个 32 们的 opencv?

    64 位的 看看 Qt 官方的 How-to https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows

    WITH_QT 这个选项 只是使 opencv 的 gui 用 qt 的 ui，如果只是用 opencv 处理图像，这个是基本不需要的。老版本（如 2.49 ）的 opencv 发布的版本里面 是同时有 32bit 和 64bit 的,如果不想折腾，下一个老版本的就行了
