Build unsuccessful when I run build_desktop_examples.sh

Unable to build mediapipe in linux (ubuntu) I get error while running build_desktop_examples.sh file

Hi @Thushar-marvel, Could you please confirm this is duplicate of https://github.com/google/mediapipe/issues/496. If not can you share the system information details to investigate further. Thanks!

[Thushar-marvel]

@sgowroji I tried to the issue #496 .Even after altering ./mediapipe/third_party/opencv_linux.BUILD it didn't work for me.

I have used Oracle VM virtual box manager to build virtual machine with ubuntu 20.04

I ran all the steps mentioned here Run the Hello World! in C++ example was successful

only the problem is when I run /build_desktop_examples.sh

Well I had met some errors like yours... I think the key to solve is you should make sure your opencv should be installed successfully AND your environment variables should be set properly.

And the build_desktop_examples.sh is too much complicated and I suggest you can build single example(face_detection ,eg) to begin, if ok, then go to the other examples.

Hi @Thushar-marvel, Could you please confirm your opencv is installed and linked correctly!

[Thushar-marvel]

Thank you, I re installed OpenCV, its working fine for me now.
