Once you have done so, you can execute code that uses GoCV with your custom environment like this: go run -tags customenv. Please note that you will need to run these 2 lines of code one time in your current session in order to build or run the code, in order to setup the needed ENV variables. When building with this tag you will need to supply the CGO environment variables yourself.įor example: export CGO_CPPFLAGS='-I/usr/local/include'Įxport CGO_LDFLAGS='-L/usr/local/lib -lopencv_core -lopencv_face -lopencv_videoio -lopencv_imgproc -lopencv_highgui -lopencv_imgcodecs -lopencv_objdetect -lopencv_features2d -lopencv_video -lopencv_dnn -lopencv_xfeatures2d' This behavior can be disabled by supplying -tags customenv when building/running your application.

If you are running a version of Go older than v1.10 and not modifying GoCV source, precompile the GoCV package to significantly decrease your build times: go install gocv.io/x/gocvīy default, pkg-config is used to determine the correct flags for compiling and linking OpenCV. The version program should output the following: gocv version: 0.28.0Īfter the installation is complete, you can remove the extra files and folders: make clean Now you should be able to build or run any of the examples: go run. To verify your installation you can run one of the included examples.įirst, change the current directory to the location of the GoCV repo: cd $GOPATH/src/gocv.io/x/gocv

Once the code is built, you are ready to install: make sudo_install Now, download the OpenCV 4.5.3 and OpenCV Contrib source code: make downloadīuild everything. OpencCV is a multi-platform library, but this article will be focused only on OpenCV using Linux operating system ( although, just the installation of the OpenCV library and video camera is platform-specific, all examples in this article should compile on any platform where.

If you have already run make install as described above, you do not need to run any of these commands. Here are details for each of the steps that are performed during the “Quick Install”. That’s it, now you are ready to use GoCV. If it works correctly, at the end of the entire process, the following message should be displayed: gocv version: 0.28.0 The following commands should do everything to download and install OpenCV 4.5.3 on Linux: make install Now you can run the needed installation steps listed below. Install the GoCV package: go get -u -d gocv.io/x/gocvĬhange directories into the newly installed package directory: cd $GOPATH/src/gocv.io/x/gocv The installation performed by the Makefile is minimal, so it may remove OpenCV options such as Python or Java wrappers if you have already installed OpenCV some other way. If you already have installed OpenCV, you do not need to do so again. You can use make to install OpenCV 4.5.3 with the handy Makefile included with this repo.
