Description

After installing following instructions, I get the following error when I try to see the version

go run ./cmd/version/main.go

Steps to Reproduce

Install latest version on Ubuntu 16.04 following READ.md

Your Environment

Operating System and version: Ubuntu 16.04
OpenCV version used: 4
How did you install OpenCV? Following instructions on READ.md. I tried both quick and complete install
GoCV version used: Latest
Go version: go1.11.1 linux/amd64
Did you run the env.sh or env.cmd script before trying to go run or go build? No
I had a previous installation working, executed git pull and it stopped working. I deleted the folder and tried to reinstall it several times and got this error every time.

I uninstalled an OpenCV version which was installed with an Intel SDK and tried the whole installation once again, and I am getting this error whenever I run the program:

# runtime/cgo
/usr/bin/ld: cannot find -ldliaPlugin
/usr/bin/ld: cannot find -lHeteroPlugin
/usr/bin/ld: cannot find -lMKLDNNPlugin
/usr/bin/ld: cannot find -lmyriadPlugin
/usr/bin/ld: cannot find -linference_engine
/usr/bin/ld: cannot find -lclDNNPlugin
/usr/bin/ld: cannot find -lopencv_pvl
collect2: error: ld returned 1 exit status

It worked after changing CGO_LDFLAGS to null

CGO_LDFLAGS=-L/opencv/lib -L/deployment_tools/inference_engine/lib/ubuntu_16.04/intel64 -lpthread -ldl -ldliaPlugin -lHeteroPlugin -lMKLDNNPlugin -lmyriadPlugin -linference_engine -lclDNNPlugin -lopencv_core -lopencv_pvl -lopencv_videoio -lopencv_imgproc -lopencv_highgui -lopencv_imgcodecs -lopencv_objdetect -lopencv_features2d -lopencv_video -lopencv_dnn -lopencv_calib3d

CGO_LDFLAGS=

This solution seems a bit forced, any thoughts or suggestions? Or should I close this issue?

Hello @marcosantar93 if you want to use GoCV with the Intel OpenVINO you must follow these instructions here: https://github.com/hybridgroup/gocv/tree/master/openvino

You cannot "mix and match" both versions at the same time. You may either use the OpenCV 4.0 that you would build from source from the main project README (https://github.com/hybridgroup/gocv/blob/master/README.md) or you may use the OpenVINO install by following the OpenVINO instructions as linked above.

Hope that helps!

I'll try it in a few days and let you know. Thanks for the answer!

I could complete the installation from the link that you provided. However, when I run the openvino version program, I get this error:

/usr/bin/ld: cannot find -ldliaPlugin
collect2: error: ld returned 1 exit status

I could find that library on the lib directories referenced on env.sh, so I deleted the -ldliaPlugin flag and I could see the openvino version without any problems. However, when I run the DNN-detection example, I get the following error whenever I set the target to NetTargetFP16 or NetTargetFP32. It runs without problems with backend set to OpenVINO and NetTargetCPU.

I checked and the library is where it should.
