This will build Go and run a series of tests, although they will take somewhere between an hour and two hours to complete. It is easy to learn and work with Golang, and it can be read easily by other developers. Use Git or checkout with SVN using the web URL. CGO_ENABLED=1) is based on the concept of lightweight Linux containers.All the necessary Go tool-chains, C cross compilers and platform headers/librarieshave been assembled into a single Docker container, which can then be called as ifa single command to compile a Go package to various platforms and architectures. download the GitHub extension for Visual Studio, instead of specifying it in each build it can be set globally during docker run, List of directories containing pkg-config files, GPG_KEY - defaults to /secrets/key.gpg. The output of cross-compilation is not directly in $GOPATH/bin, but in $GOPATH/bin/$GOOS_$GOARCH. How to cross compile from Linux for Mac There are a lot of examples of cross compiling a go binary for usage on a linux and/or windows machine, but I can't find any info regarding the reverse. If done correctly, adding additional test cases is as simple as a new element in the test table. Actual work to create cross-compile environment is done by osxcross and golang-cross, To run build with CGO each entry requires some environment variables, PKG_CONFIG_SYSROOT_DIR Modifies -I and -L to use the directories located in target sys root. for pkg-config and datadir is the datadir for pkg-config when it was installed. If nothing happens, download GitHub Desktop and try again. for this example we will install libftdi1-dev, libusb-1.0-0-dev and opencv4. On the other hand, if we wanted to compile for Microsoft Windows, we’d simply set GOOS=windows and GOARCH=386. This branch is 2 commits ahead of troian:master.

If nothing happens, download the GitHub extension for Visual Studio and try again. To do so, we simply set two environment variables: $GOOS, which is the target operating system, and $GOARCH, which is the target processor. Docker container to turn CGO cross-compilation pain into a pleasure on variety of platforms including usage of custom sysroots. How do you use one system to compile binaries that will work on the other? You signed in with another tab or window. Next, we'd want to cross compile binaries for OSX/Linux/Windows (386/x64).
