以前我移植Ti平台的时候 好像LDLIBS = 还要加这些库的
-lstdc++   -lpthread  -lrt

加了 还是没用

  逗比我知道，并且解决了国内的嵌入式移植教程有问题。
问题特征  你试一下  readelf  -d  libopencv_objdetect.so
如果右端  Name/Value 一列 显示 的是
shared  library：[../../libopencv_core.so]  
shared library : [../../libopencv_imgproc.so]
.....
出现上述问题的库用来编译这个库就会出现你上面的警告，执行程序执行时需要 在执行程序所在目录../../lib 存放so库
哈哈！ 麻痹，老子找了一周才发现TMD网上的垃圾海思移植教程都他妈的骗人的。
然后自己研究了一下opencv配置问题解决了
清查看opencv源码下platform 下面目录都有一个toolchain.cmake 自己把握 改下工具链 就可以了

你加载的是动态库，看下对应目录下面是否有动态库的文件？
