@Maweiten 你好，我在jetson nano上编译时也遇到了相同的错误，请问你解决了吗？

I've had the same error with the Raspberry Pi 4 with 64-bit OS. The problem is that OpenCV requires RTTI (you use /usr/local/include/opencv2/flann/params.h in the build) and ncnn has default RTTI switched off. Please build your ncnn framework again with -DNCNN_DISABLE_RTTI=OFF. See also #2694
