    这是一个创建于 2210 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

    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
