#
# This file contains logic to ease porting of Go binaries using the
# `go` command.
#
# Feature: go
# Usage: USES=go
# Valid ARGS: (none), modules, no_targets, run
#
# (none) Setup GOPATH and build in GOPATH mode.
# modules If the upstream uses Go modules, this can be set to build
# in modules-aware mode.
# no_targets Indicates that Go is needed at build time as a part of
# make/CMake build. This will setup build environment like
# GO_ENV, GO_BUILDFLAGS but will not create post-extract, do-build
# and do-install targets.
# run Indicates that Go is needed at run time and adds it to
# RUN_DEPENDS.
#
# You can set the following variables to control the process.
#
# GO_PKGNAME
# The name of the package when building in GOPATH mode. This
# is the directory that will be created in GOPATH/src and seen
# by the `go` command. 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. If not set explicitly, defaults to
# 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}. Specifying a full path
# like ${PREFIX}/sbin/binary will install the resulting binary
# as ${PREFIX}/sbin/binary. Using just simple filename is a
# shortcut to installing it as ${PREFIX}/bin/filename.
#
# CGO_CFLAGS
# Additional CFLAGS variables to be passed to the C compiler by the `go`
# command
#
# CGO_LDFLAGS
# Additional LDFLAGS variables to be passed to the C compiler by the `go`
# command
#
# GO_BUILDFLAGS
# Additional build arguments to be passed to the `go install` command
#
# GO_PORT
# The Go 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.
#
# This variable must not be set by individual ports!
