Installation error on Arch Linux about gocv

[deadprogram]

Hi, @DeadNumbers can you please try:

go get -d -u github.com/hybridgroup/gocv

The problem might be that go is trying to install before the pre-reqs are installed, or before the ENV vars are set as needed for your platform.

[DeadNumbers]

@deadprogram do go get -d -u github.com/hybridgroup/gocv then

You probably need to do the same thing as mentioned here, to setup your env vars:

#5 (comment)

[deadprogram]

Just noticed you had done that.

Possibly installed to a different place? Check out these tips for non-Ubuntu Linux https://github.com/hybridgroup/gocv#other-linux-installations

[DeadNumbers]

@deadprogram my ENV is diferent.

user@arch ~ ➤ pkg-config --cflags opencv
-I/usr/include/opencv
user@arch ~ ➤ pkg-config --libs opencv
-L/lib64 -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab -ltbb -lGL -lGLU -lrt -lpthread -lm -ldl

I edit env.sh to this

elif [[ "$uname_val" == "Linux" ]]; then
  export CGO_CPPFLAGS="-I/usr/include"
  export CGO_CXXFLAGS="--std=c++1z"
  export CGO_LDFLAGS="-L/lib64 -lopencv_core -lopencv_videoio -lopencv_imgproc -lopencv_highgui -lopencv_imgcodecs -lopencv_objdetect -lopencv_calib3d"
  echo "Environment variables configured for Linux"

Are you able to run an individual cmd example from GoCV via go run like the example?

go run ./cmd/version/main.go

I do not currently have an Arch setup to test on, sorry to ask so many questions.

Is the ~/go directory the same as your $GOPATH points to? Also, did you uninstall any previous versions of OpenCV before installing v3.3 or did you already have v3.3 installed?

[DeadNumbers]

sorry, forgot to update to 3 :stupid:
