构建你的程序
Makefile
通过在根目录中编写包含常用命令的./Makefile来帮助用户编译应用程序：
注意：下面的 Makefile 包含一些与Cosmos SDK 和 Tendermint 的 Makefiles 相同的命令。
all: install
install: go.sum
go install -tags "$(build_tags)" ./cmd/nsd
go install -tags "$(build_tags)" ./cmd/nscli
go.sum: go.mod
@echo "--> Ensure dependencies have not been modified"
@go mod verify

如何增加 Ledger Nano S 支持？
这需要一些小的修改：
- 创建文件
Makefile.ledger，填入下面的内容：
LEDGER_ENABLED ?= true
build_tags =
ifeq ($(LEDGER_ENABLED),true)
ifeq ($(OS),Windows_NT)
GCCEXE = $(shell where gcc.exe 2> NUL)
ifeq ($(GCCEXE),)
$(error gcc.exe not installed for ledger support, please install or set LEDGER_ENABLED=false)
else
build_tags += ledger
endif
else
UNAME_S = $(shell uname -s)
ifeq ($(UNAME_S),OpenBSD)
$(warning OpenBSD detected, disabling ledger support (https://github.com/cosmos/cosmos-sdk/issues/1988))
else
GCC = $(shell command -v gcc 2> /dev/null)
ifeq ($(GCC),)
$(error gcc not installed for ledger support, please install or set LEDGER_ENABLED=false)
else
build_tags += ledger
endif
endif
endif
endif

- 在
Makefile文件首部添加include Makefile.ledger：
include Makefile.ledger
all: install
install: go.sum
GO111MODULE=1 go install -tags "$(build_tags)" ./cmd/nsd
GO111MODULE=1 go install -tags "$(build_tags)" ./cmd/nscli
go.sum: go.mod
@echo "--> Ensure dependencies have not been modified"
GO111MODULE=1 @go mod verify

go.mod
Golang有一些依赖管理工具。在本教程中，你将使用Go Modules。Go Modules使用仓库根目录中的go.mod文件来定义应用程序所需的依赖项。Cosmos SDK 应用程序目前依赖于某些库的特定版本。以下列表包含所有必需的版本。开始构建之前，用下面的内容替换./go.mod文件。
