Binaries of this type must be executable on the current 15 # system, so the only common reason to set this is to set 16 # GOHOSTARCH=386 on an amd64 machine. 17 # 18 # GOARCH: The target architecture for installed packages and tools. 19 # 20 # GOOS: The target operating system for installed packages and tools. 21 # 22 # GO_GCFLAGS: Additional go tool compile arguments to use when 23 # building the packages and commands. 24 # 25 # GO_LDFLAGS: Additional go tool link arguments to use when 26 # building the commands. 27 # 28 # CGO_ENABLED: Controls cgo usage during the build. Set it to 1 29 # to include all cgo related files, .c and .go file with "cgo" 30 # build directive, in the build.
