edgex0.7.1_1.0.1的X86编译和交叉编译

一. X86编译

1． 安装zeromq库

根据setup script安装：

wget https://github.com/zeromq/libzmq/releases/download/v4.2.2/zeromq-4.2.2.tar.gz
tar xvzf zeromq-4.2.2.tar.gz
cd zeromq-4.2.2
./configure
sudo make install
sudo ldconfig
ldconfig -p | grep zmq
libzmq.so.5 (libc6,x86-64) => /usr/local/lib/libzmq.so.5
libzmq.so (libc6,x86-64) => /usr/local/lib/libzmq.so

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/

2． 获取源码

go get github.com/edgexfoundry/edgex-go

3． 安装依赖包

edgex0.7.1采用glide管理go工程

提取如下依赖包错误：

golang.org/x/net/proxy
golang.org/x/net/websocket
golang.org/x/net/context/ctxhttp
golang.org/x/sys/windows

glide搜索到的包应该以git或svn等vcs，但上述proxy、websocket和ctxhttp是net的子包，golang.org/x/net/采用git管理。同样，golang.org/x/sys采用git管理，windows是sys的子目录。此时，可在glide.yaml中指定golang.org/x/net和golang.org/x/sys的子包关系:

- package: golang.org/x/net 
  subpackages:
  - proxy 
  - websocket 
  - context/ctxhttp
- package: golang.org/x/sys
  subpackages:
  - windows

此时，直接设置git管理包的镜像即可，mirror设置：

glide mirror set https://golang.org/x/net https://github.com/golang/net --vcs git
glide mirror set golang.org/x/sys https://github.com/golang/sys --vcs git

此时，glide install成功执行。

注：若安装的依赖包出现错误，可能是包版本不对，需要在glide.yaml中指定软件包的版本（如master中已不包含原来的目录，导致包检索依赖不成功，github.com/influxdata/influxdb/client/v2最新版没有client目录）。

edgex1.0.1采用GO111MODULE管理

首先确保go版本在1.11之上，golang从1.11开始内置module管理功能。

由于golang.org被墙，需要在go.mod中增加替换：

replace (
    bitbucket.org/bertimus9/systemstat => github.com/sigma/systemstat v0.0.0-20180207000608-0eeff89b0690
    golang.org/x/crypto => github.com/golang/crypto v0.0.0-20181029021203-45a5f77698d3
    golang.org/x/net => github.com/golang/net v0.0.0-20181201002055-351d144fa1fc
    golang.org/x/sync => github.com/golang/sync v0.0.0-20181221193216-37e7f081c4d4
    golang.org/x/sys => github.com/golang/sys v0.0.0-20181026203630-95b1ffbd15a5
    golang.org/x/tools => github.com/golang/tools v0.0.0-20181112210238-4b1f3b6b1646
)

4． 编译

make prepare
make build

5． 启动mongodb，然后直接运行make run即可。

在自目录保存数据，如/home/wang/edgex/db。 

sudo mongod --dbpath "/home/wang/edgex/db"
mongo init_mongo.js
sudo mongod --dbpath "/home/wang/edgex/db" --shutdown
sudo chown -R mongodb:mongodb "/home/wang/edgex/db"
sudo mongod --dbpath "/home/wang/edgex/db" --auth 
sudo mongod --dbpath "/home/wang/edgex/db" --bind_ip_all   ;允许远程访问数据库

make run

若运行报错，可能是mongo权限问题，去除--auth。

6.  测试随机数设备

参考4.3.1. Writing a Device Service in Go编译随机数简单设备，运行device-simple可执行文件。

若不报错，且数据一直上报，可通过如下地址查询数据：

http://localhost:48080/api/v1/event/device/RandNum-Device01/100

http://172.61.1.125:48080/api/v1/event
http://172.61.1.125:48071/api/v1/registration
http://172.61.1.125:48080/api/v1/event/count
http://172.61.1.125:48080/api/v1/valuedescriptor
http://172.61.1.125:48081/api/v1/device
http://172.61.1.125:48081/api/v1/deviceservice

可注册mosquitto云平台，上传至云平台：

POST to http://192.168.134.144:48071/api/v1/registration
{"name":"MyMQTTTopic","addressable":{"name":"MyMQTTBroker","protocol":"TCP","address":"192.168.134.144","port":1883,"publisher":"EdgeXExportPublisher","user":"wang","password":"mypass","topic":"a/b/c"},"format":"JSON","enable":true,"destination":"MQTT_TOPIC"}

在主机192.168.134.144上开启mosquitto，并：

$ mosquitto_sub -t a/b/c
{"id":"5cecfb6d902d0f90ade77aca","pushed":0,"device":"RandNum-Device01","created":1559034733008,"modified":0,"origin":1559034733003,"schedule":null,"event":null,"readings":[{"id":"5cecfb6d902d0f90ade77acb","pushed":0,"created":1559034733008,"origin":1559034733002,"modified":0,"device":"RandNum-Device01","name":"Random","value":"58"}]}

二. 交叉编译

在Ubuntu16.04上交叉编译edgex 1.0.1，编译后的程序运行于OKMX6DL-S3（Cortex-A9，32位，双核）。

2.1 交叉编译工具链

板卡自带交叉编译工具链应用

. /opt/fsl-imx-x11/4.1.15-2.1.0/environment-setup-cortexa9hf-neon-poky-linux-gnueabi
/opt/fsl-imx-x11/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
/opt/fsl-imx-x11/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++

通用交叉编译工具链应用

sudo apt-get install g++-5-arm-linux-gnueabihf g++-5-arm-linux-gnueabihf
sudo update-alternatives --install /usr/bin/arm-linux-gnueabihf-gcc arm-linux-gnueabihf-gcc /usr/bin/arm-linux-gnueabihf-gcc-5 100 --slave /usr/bin/arm-linux-gnueabihf-g++ arm-linux-gnueabihf-g++ /usr/bin/arm-linux-gnueabihf-g++-5

注：板卡自带交叉编译工具链编译edgex不成功，随采用通用交叉编译工具链。

2.2 交叉编译zeromq

板卡自带交叉编译工具链应用

./configure --prefix=/home/wang/edgex/edgex_mx6dl/zeromq-4.2.2/winstall --host=arm-poky-linux-gnueabi  CC="/opt/fsl-imx-x11/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc --sysroot=$SDKTARGETSYSROOT -mfloat-abi=hard" CXX="/opt/fsl-imx-x11/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++ --sysroot=$SDKTARGETSYSROOT -mfloat-abi=hard "
make && make install

通用交叉编译工具链应用

./configure --prefix=/home/wang/edgex/edgex_mx6dl/zeromq-4.2.2/winstall --host=arm-poky-linux-gnueabi  CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++
make && make install

2.3 交叉编译edgex

采用通用交叉编译器编译edgex，解决包依赖关系后，修改Makefile中编译选项：

GO=GOARCH=arm CGO_ENABLED=0 GO111MODULE=on go
GOCGO=GOARCH=arm CGO_ENABLED=1 CC="arm-linux-gnueabihf-gcc" 
CGO_CFLAGS="-I/home/wang/edgex/edgex_mx6dl/zeromq-4.2.2/winstall/include" CGO_LDFLAGS="-L/home/wang/edgex/edgex_mx6dl/zeromq-4.2.2/winstall/lib -lzmq" 
GO111MODULE=on go

然后执行如下命令编译

make build

将生成的zeromq库文件winstall，edgex生成的bin和cmd，及mongodb编译而成的bin（mongodb自编译有问题，从网上下载2.6.4版本可执行文件）拷贝到板卡并安装。

先启动mongodb，然后执行edgex，同X86上运行顺序，可正确执行并运行。

三. docker镜像制作

生成所有docker可运行命令：

make docker

生成单独docker可运行命令（以docker_export_distro为例）：

make docker_export_distro

docker_export_distro:
    docker build 
        -f cmd/export-distro/Dockerfile 
        --label "git_sha=$(GIT_SHA)" 
        -t edgexfoundry/docker-export-distro-go:$(GIT_SHA) 
        -t edgexfoundry/docker-export-distro-go:$(DOCKER_TAG) 
        .

Dockerfile文件如下：

#

ENTRYPOINT ["/export-distro","--registry","--profile=docker","--confdir=/res"]

上述命令生成两个镜像（其中一个在cache中，另一个为实际镜像，两个tag），没有容器产生（docker ps -a不显示，容器被删除）：

export-distro容器镜像生成日志：

make docker_export_distro
docker build 
        -f cmd/export-distro/Dockerfile 
        --label "git_sha=48146ead559bd9f27e80af344e3cf787530a1539" 
        -t edgexfoundry/docker-export-distro-go:48146ead559bd9f27e80af344e3cf787530a1539 
        -t edgexfoundry/docker-export-distro-go:1.0.2-dev 
        .

注：生成其他docker镜像时，都会使用cache中镜像（repository和tag都是<none>），编译一次供多个容器使用。可以通过docker tag保留容器。
