在 Linux 上从源代码构建 OpenCV 和 OpenCV_Contrib 时出现构建错误

Question

我正在使用 OpenCV_contrib 在 Linux 上构建 OpenCV，但我无法使其工作。 单独的 OpenCV 可以毫无错误地构建。

单独编译 OpenCV 时，它可以找到。

cmake -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4/modules ..

$ 制作 j5

在制作过程中，它以 100% 失败，?????????????????????????????????

Answer 1

我从官网下载了opencv源代码，并从Github克隆了opencv_contrib。这不是一个好主意，我遇到了问题。

我从 Github 为 opencv 和 opencv_contrib 克隆了完全相同的版本，这次它运行良好。

git clone -b 3.4 https://github.com/opencv/opencv
git clone -b 3.4 https://github.com/opencv/opencv_contrib

Answer 2

在cmake和make之前运行make clean，应该可以解决问题。
