Binaries of this type must be executable on the current 13 # system, so the only common reason to set this is to set 14 # GOHOSTARCH=386 on an amd64 machine. 15 # 16 # GOARCH: The target architecture for installed packages and tools. 17 # 18 # GOOS: The target operating system for installed packages and tools. 19 # 20 # GO_GCFLAGS: Additional 5g/6g/8g arguments to use when 21 # building the packages and commands. 22 # 23 # GO_LDFLAGS: Additional 5l/6l/8l arguments to use when 24 # building the commands. 25 # 26 # GO_CCFLAGS: Additional 5c/6c/8c arguments to use when 27 # building. 28 # 29 # CGO_ENABLED: Controls cgo usage during the build. Set it to 1 30 # to include all cgo related files, .c and .go file with "cgo" 31 # build directive, in the build.
