示例1: determineLinkMode

// determineLinkMode sets Linkmode.
//
// It is called after flags are processed and inputs are processed,
// so the Linkmode variable has an initial value from the -linkmode
// flag and the iscgo externalobj variables are set.
func determineLinkMode(ctxt *Link) {
	switch Linkmode {
	case LinkAuto:
		// The environment variable GO_EXTLINK_ENABLED controls the
		// default value of -linkmode. If it is not set when the
		// linker is called we take the value it was set to when
		// cmd/link was compiled. (See make.bash.)
		switch obj.Getgoextlinkenabled() {
		case "0":
			if needed, reason := mustLinkExternal(ctxt); needed {
				Exitf("internal linking requested via GO_EXTLINK_ENABLED, but external linking required: %s", reason)
			}
			Linkmode = LinkInternal
		case "1":
