17.33. go

Important:

Ports should not be created for Go libs, see Section 6.29, “Go Libraries” for more information.

Possible arguments: (none), modules, no_targets, run

Sets default values and targets used to build Go software. A build dependency on the Go compiler port selected via GO_PORT is added. By default the build is performed in GOPATH mode. If Go software uses modules, the modules-aware mode can be switched on with modules argument. no_targets will setup build environment like GO_ENV, GO_BUILDFLAGS but skip creating post-extract, do-build and do-install targets. run will also add a run dependency on what is in GO_PORT.

The build process is controlled by several variables:

GO_PKGNAME

The name of the Go package when building in GOPATH mode. This is the directory that will be created in ${GOPATH}/src. If not set explicitly and GH_SUBDIR or GL_SUBDIR is present, GO_PKGNAME will be inferred from it. It is not needed when building in modules-aware mode.

GO_TARGET

The packages to build. The default value is ${GO_PKGNAME}. GO_TARGET can also be a tuple in the form package:path where path can be either a simple filename or a full path starting with ${PREFIX}.

CGO_CFLAGS

Additional CFLAGS values to be passed to the C compiler by go.

CGO_LDFLAGS

Additional LDFLAGS values to be passed to the C compiler by go.

GO_BUILDFLAGS

Additional build arguments to be passed to go install.

GO_PORT

The Go compiler port to use. By default this is lang/go but can be set to lang/go-devel in make.conf for testing with future Go versions.

Warning:

This variable must not be set by individual ports!

See Section 6.5.8, “Building Go Applications” for usage examples.
