How to run the ASRCF_Demo.

[Lee-AI-sco]

Environment: ubuntu16.04 + GTX1660 + cuda8.0 + cudnn6.0 + opencv3.4.1 + matlab2017a.
The version of gcc and g++: 4.9

I have downloaded the code from github.
First step: run the install
the result is:

I do not how to slove the problem,the version of opencv is 3.4.1 on my computer,and I know the version of ASRCF is opencv2.4.1.maybe is the version of opencv ,but I have configured many projects with opencv3.4.1,so I don't want to remove the opencv3.4.1 ,Can you help you.
Thank you very much.

Install opencv 2.4 and add this line in your bashrc.
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6:/usr/lib/x86_64-linux-gnu/libopencv_core.so.2.4
You can install multiple versions of opencv and then specify the path to the version you need.

Thanks a lot,I have done it.

Hello, I also encountered the problem of opencv when using ubuntu20.04 today. Can I just install opencv2.4 on the computer? Is there any need to pay attention to the version of gcc? Thank you very much for your reply

I think it's hard to install opencv 2.4, because it only support cuda 8.0 or a lower version , but GPUs now such as GTX 3090 need cuda 11.1 or higher version. So I think the only way to run it is changing the version of opencv that the ASRCF uses. Honestly, I don't know how to change it. So I want to ask the author this question.
