Makefile #

Go Makefile 样例 #

include .env

PROJECTNAME=$(shell basename "$(PWD)")

# Go related variables.
GOBASE=$(shell pwd)
GOPATH="$(GOBASE)/vendor:$(GOBASE)"
GOBIN=$(GOBASE)/bin
GOFILES=$(wildcard *.go)

# Redirect error output to a file, so we can show it in development mode.
STDERR=/tmp/.$(PROJECTNAME)-stderr.txt

# PID file will keep the process id of the server
PID=/tmp/.$(PROJECTNAME).pid

# Make is verbose in Linux. Make it silent.
MAKEFLAGS += --silent

## install: Install missing dependencies. Runs `go get` internally. e.g; make install get=github.com/foo/bar
install: go-get

## start: Start in development mode. Auto-starts when code changes.
start:
    bash -c "trap 'make stop' EXIT; $(MAKE) compile start-server watch run='make compile start-server'"

## stop: Stop development mode.
stop: stop-server

start-server: stop-server
	@echo "  >  $(PROJECTNAME) is available at $(ADDR)"
	@-$(GOBIN)/$(PROJECTNAME) 2>&1 & echo $$! > $(PID)
	@cat $(PID) | sed "/^/s/^/  \>  PID: /"

stop-server:
	@-touch $(PID)
	@-kill `cat $(PID)` 2> /dev/null || true
	@-rm $(PID)

## watch: Run given command when code changes. e.g; make watch run="echo 'hey'"
watch:
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) yolo -i . -e vendor -e bin -c "$(run)"

restart-server: stop-server start-server

## compile: Compile the binary.
compile:
	@-touch $(STDERR)
	@-rm $(STDERR)
	@-$(MAKE) -s go-compile 2> $(STDERR)
	@cat $(STDERR) | sed -e '1s/.*/\nError:\n/'  | sed 's/make\[.*/ /' | sed "/^/s/^/     /" 1>&2

## exec: Run given command, wrapped with custom GOPATH. e.g; make exec run="go test ./..."
exec:
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) $(run)

## clean: Clean build files. Runs `go clean` internally.
clean:
	@(MAKEFILE) go-clean

go-compile: go-clean go-get go-build

go-build:
	@echo "  >  Building binary..."
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) go build -o $(GOBIN)/$(PROJECTNAME) $(GOFILES)

go-generate:
	@echo "  >  Generating dependency files..."
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) go generate $(generate)

go-get:
	@echo "  >  Checking if there is any missing dependencies..."
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) go get $(get)

go-install:
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) go install $(GOFILES)

go-clean:
	@echo "  >  Cleaning build cache"
	@GOPATH=$(GOPATH) GOBIN=$(GOBIN) go clean

交叉编译 #

golang 交叉编译很简单的,只要设置几个环境变量就可以了

# mac上编译linux和windows二进制
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build

# linux上编译mac和windows二进制
CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build

# windows上编译mac和linux二进制
SET CGO_ENABLED=0 SET GOOS=darwin SET GOARCH=amd64 go build main.go
