我正在使用 opencv C++ 代码，以便我可以更改一些代码内容并编译它并获得结果。问题是我能够在我的 JNI 接口函数中使用 opencv c++ 的函数。在代码顶部添加标头后，我可以使用这些函数。当我运行编译时，我收到未定义的引用错误。
我这样做是为了 android 编码。
错误如下（错误很少）：

我尝试了很多从谷歌得到的东西，但我没有得到任何结果。
下面是用于调用 Opencv C++ 代码的 JNI 代码。
#include "com_whizpool_opencvtest_MainActivity.h"
#include <opencv/cv.h>
#include <opencv/highgui.h>
using namespace cv;
extern "C"
{
JNIEXPORT jlong JNICALL Java_com_whizpool_opencvtest_MainActivity_imread_11(JNIEnv *env, jclass obj, jstring string)
{
const char *w_buf = env->GetStringUTFChars(string, 0);
Mat imgMat = imread("abc", 0);
return 0;
}
}
