编译分支

当前编译的是主分支

https://github.com/zhiyong0804/brks/tree/master

重点：

(1)理解src/CMakeList.txt的意义再去考虑编译；

(2)如果自己在下面的各个编译中，没有找到相关的目录，则自行创建。

(3)不要盲目一遍一遍地去试，遇到编译错误，先思考下哪里可能出问题再百度查找，如果百度不能解决则在群里提问。

对于CMakeList.txt不理解的可以参考 https://www.jianshu.com/p/89f0836d9f33

0. 先理解cmake

先理解src目录下的CMakeList.txt，只有理解了其意义，去编译工程才有意义，否则就是浪费时间。

(1)INCLUDE_DIRECTORIES指定包含的目录；

(2)LINK_DIRECTORIES库文件的目录

(3)TARGET_LINK_LIBRARIES需要链接哪一些库

(4)ADD_SUBDIRECTORY包含的子目录

(5)AUX_SOURCE_DIRECTORY查找在某个路径下的所有源文件

#NodeServer cmake config file for src

#cmake version request

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

#project name工程名

PROJECT(brks)

#Head file path 头文件

# ../third/include是第三方库文件的头文件所在路径

已经编译的库文件

image.png

需要自己再编译的库

thrift event curl jsoncpp 这部分我编译成静态库放到brks/third的include和lib目录

mysqlclient lua 直接编译到linux系统

target_link_libraries

TARGET_LINK_LIBRARIES(myProject comm) # 连接libhello.so库，默认优先链接动态库，如果要静态链接请显式链接libcomm.a

TARGET_LINK_LIBRARIES(myProject libcomm.a) # 显式指定链接静态库

TARGET_LINK_LIBRARIES(myProject libcomm.so) # 显式指定链接动态库

再如：

TARGET_LINK_LIBRARIES(myProject libcomm.so)　　#这些库名写法都可以。

TARGET_LINK_LIBRARIES(myProject comm)

TARGET_LINK_LIBRARIES(myProject -lcomm)

1. 我编译完后third的include和lib

third/include

lqf@ubuntu:~/dongnao/brks/third/include$ ls

boost curl evdns.h event.h event2 evhttp.h evrpc.h evutil.h include.am iniparser json log4cpp thrift tinyxml

third/lib

lqf@ubuntu:~/dongnao/brks/third/lib$ ls

boost curl event iniparser jsoncpp log4cpp thrift tinyxml

2. 编译第三方库

2.1. 编译log4cpp

log4cpp 已经编译好，这里只是提供一个编译的方法

lqf@ubuntu:~/dongnao/brks_third/log4cpp$ git clone https://github.com/orocos-toolchain/log4cpp.git

lqf@ubuntu:~/dongnao/brks_third/log4cpp$ git tag

...

v2.8.1

v2.8.3

v2.9.0-rc1

# 选择tag，不用master，master容易有bug

lqf@ubuntu:~/dongnao/brks_third/log4cpp$ git checkout v2.9.0-rc1

修改CMakeList.txt

将动态库改为静态库(由SHARED改为STATIC)

image.png

使用cmake的方式编译

cd log4cpp

mkdir build

cd build

cmake ..

make

编译后的build目录下

将include的log4cpp整个文件夹拷贝到brks/third/include

将 liborocos-log4cpp.a重命名 liblog4cpp.a并拷贝到brks/third/lib/log4cpp

lqf@ubuntu:~/dongnao/brks_third/log4cpp/build$ ls

CMakeCache.txt CMakeFiles Makefile cmake_install.cmake configure-tryouts include liborocos-log4cpp.a orocos-log4cpp.pc

2.2 编译tinyxml

wget https://nchc.dl.sourceforge.net/project/tinyxml/tinyxml/2.6.2/tinyxml_2_6_2.zip

unzip tinyxml_2_6_2.zip

cd tinyxml

需要修改tinyxml的Makefile以编译静态库

(1)使用vim或者其他的编辑器打开Makefile文件

(2)将其中的注释为Targets of the build的下一行OUTPUT := xmltest

一行修改为：OUTPUT := libtinyxml.a

(3)将其中的注释为Source files 的下一行SRCS：=tinyxml.cpp tinyxml-parser.cpp xmltest.cpp tinyxmlerror.cpp tinystr.cpp中的xmltest.cpp删除，因为它只是一个测试源文件，不需要编译。修改后为：SRCS := tinyxml.cpp tinyxmlparser.cpp tinyxmlerror.cpp tinystr.cpp

(4)将其中的Output的下一行的${LD} -o $@ ${LDFLAGS} ${OBJS} ${LIBS} ${EXTRA_LIBS}修改为：${AR} $@ ${LDFLAGS} ${OBJS} ${LIBS} ${EXTRA_LIBS}。修改后为：

${OUTPUT}: ${OBJS}

${AR} $@ ${LDFLAGS} ${OBJS} ${LIBS} ${EXTRA_LIBS}

# ${LD} -o $@ ${LDFLAGS} ${OBJS} ${LIBS} ${EXTRA_LIBS}

(5)将Makefile的倒数第二行 xmltest.o：tinyxml.h tinystr.h，注释掉，因为不需要将演示程序添加到静态库中。然后保存退出。

#xmltest.o: tinyxml.h tinystr.h

(6)在终端下进入Makefile所在目录，执行make命令编译，即可在Makefile所在目录下生成libtinyxml.a文件。

编译完后的目录

lqf@ubuntu:~/dongnao/brks_third/tinyxml$ ls

Makefile readme.txt tinystr.h tinyxml.o tinyxmlerror.cpp utf8test.gif xmltest.cpp

changes.txt tinyXmlTest.vcxproj tinystr.o tinyxml.sln tinyxmlerror.o utf8test.xml xmltest.o

docs tinyXmlTestSTL.vcxproj tinyxml.cpp tinyxmlSTL.vcxproj tinyxmlparser.cpp utf8testverify.xml

libtinyxml.a tinystr.cpp tinyxml.h tinyxml_lib.vcxproj tinyxmlparser.o xmltest

(1)将tinyxml.h拷贝到brks/third/include/tinyxml

(2)将libtinyxml.a拷贝到brks/third/lib/tinyxml

2.3 安装jsoncpp

JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式。

先安装scons

sudo apt-get install scons

下载和解压

wget https://nchc.dl.sourceforge.net/project/jsoncpp/jsoncpp/0.5.0/jsoncpp-src-0.5.0.tar.gz

tar -zxvf jsoncpp-src-0.5.0.tar.gz

编译和安装

cd jsoncpp-src-0.5.0

scons platform=linux-gcc

拷贝头文件和库文件

生成的静态库和动态库在jsoncpp-src-0.5.0/libs/linux-gcc-5.4.0目录

lqf@ubuntu:~/dongnao/brks_third/jsoncpp-src-0.5.0/libs/linux-gcc-5.4.0$ ls

libjson_linux-gcc-5.4.0_libmt.a libjson_linux-gcc-5.4.0_libmt.so

(1)将libjson_linux-gcc-5.4.0_libmt.a改名为libjsoncpp.a并拷贝到brks/third/lib/jsoncp

(2)将jsoncpp-src-0.5.0/include目录的json整个目录拷贝到brks/third/include

2.4 安装libcurl

libcurl主要功能就是用不同的协议连接和沟通不同的服务器~也就是相当封装了的sockPHP 支持libcurl(允许你用不同的协议连接和沟通不同的服务器)。, libcurl当前支持http, https, ftp, gopher, telnet, dict, file, 和ldap 协议。libcurl同样支持HTTPS证书授权，HTTP POST, HTTP PUT, FTP 上传(当然你也可以使用PHP的ftp扩展), HTTP基本表单上传，代理，cookies,和用户认证。

下载和解压

拷贝头文件和库文件

cd lib/.libs

(1)拷贝库文件到brks/third/lib/curl

cp -arf libcurl.* /home/lqf/dongnao/brks/third/lib/curl

(2)拷贝头文件curl整个目录到/brks/third/include

# 回到curl-7.61.1/include

vim src/Makefile

增加-fPIC

编译安装

make linux

sudo make install

cd src && install -p -m 0644 liblua.a /usr/local/lib

cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1

lua不需要拷贝到brks目录，在终端输入 lua -v确认是否安装成功

lqf@ubuntu:~/dongnao/brks_third/curl-7.61.1/lib/.libs$ lua -v

Lua 5.2.4 Copyright (C) 1994-2015 Lua.org, PUC-Rio

2.7 thrift编译

下载thrift-0.11.0和解压

wget http://apache.fayea.com/thrift/0.11.0/thrift-0.11.0.tar.gz

tar -zxf thrift-0.11.0.tar.gz

安装依赖项，依赖项非常多

sudo apt-get install libboost-dev libboost-test-dev libboost-program-options-dev libevent-dev automake libtool flex bison pkg-config g++ libssl-dev

编译和安装

指定安装路径，否则不知道要拷贝哪一些文件，我先把它安装到~/dongnao/brks_third/thrift_lib

编译的时候要 -with-cpp -with-lua

./configure -with-cpp -with-lua -with-boost -without-python -without-csharp -without-java -without-erlang -without-perl -without-php -without-php_extension -without-ruby -without-haskell -without-go

make

# 安装到系统/usr/local，lua脚本也需要thrift支持

sudo make install

报错

需要修改lib/lua/Makefile，大概580行

lib_LTLIBRARIES = \

libluasocket.la \

libluabpack.la \

libluabitwise.la \

liblualongnumber.la

改为

lib_LTLIBRARIES = \

libluasocket.la \

liblualongnumber.la \

libluabitwise.la \

libluabpack.la

重新编译

make

# 安装到系统默认目录

sudo make install

安装到自己的目录方便拷贝头文件和库文件

# 安装到我们自己的另外目录，以方便拷贝到brks/third下

make DESTDIR=/home/lqf/dongnao/brks_third/thrift_lib install

make install后被拷贝到~/dongnao/brks_third/thrift_lib

lqf@ubuntu:~/dongnao/brks_third/thrift_lib$ ls

bin include lib

将头文件和库文件拷贝到brks/third

进到~/dongnao/brks_third/thrift_lib/usr/local

(1)将include下的 thrift整个目录拷贝到brks/third/include

(2)将lib下的所有文件拷贝到brks/third/lib/thrift

2.8 安装mysql数据库服务器

安装命令

sudo apt-get install mysql-server

sudo apt install mysql-client

sudo apt install libmysqlclient-dev

安装后可以通过下面的命令检查mysql是否安装成功

登录mysql，输入在安装时的密码

mysql -u root -p

#输入status查看版本

mysql Ver 14.14 Distrib 5.7.24, for Linux (x86_64) using EditLine wrapper

mysql退出三种方法

mysql > exit;

mysql > quit;

mysql > \q;

3 编译共享单车

3.1 修改src/CMakeList.txt

在安装完以上第三方库后，并对src/CMakeList.txt进行修改，主要的改动如下所示

添加curl和event的包含路径

#library path

LINK_DIRECTORIES(../third/lib/curl)

LINK_DIRECTORIES(../third/lib/event)

3.2 编译共享单车

进入brks/src，并创建build目录

cd brks/src

cmake .

make

make install

lqf@ubuntu:~/dongnao/brks/src$ ./brks

./brks: error while loading shared libraries: libjsoncpp.so: cannot open shared object file: No such file or directory

将libjsoncpp改为静态链接，重新编译

cmake .

make

make install

3.3 执行共享单车

启动服务器

在make install后，执行文件brks 被安装到了brks/src目录

我们先将brks/conf下面的所有文件拷贝到brks/src

lqf@ubuntu:~/dongnao/brks/src$ cp -a ../../conf/* .

执行brks ，需要传入log的配置文件，以及brks的配置文件

sudo ./brks log.conf brks.ini

正常启动后打印

Thrift: Sat Dec 15 14:18:02 2018 TNonblockingServer: Serving with 1 io threads.

Thrift: Sat Dec 15 14:18:02 2018 TNonblockingServer: using libevent 2.1.8-stable method epoll

Thrift: Sat Dec 15 14:18:02 2018 TNonblockingServer: IO thread #0 entering loop...

测试用例

进入brks/test，先测试cases.lua，但要修改host地址以及手机号码

(1)20行，修改为：host = '127.0.0.1',

(2)116行，修改为：local r = client:brk_list_travel('18570368134')

然后执行lua cases.lua

lqf@ubuntu:~/dongnao/brks/test$ lua cases.lua

测试结果

1..1

# Started on Sat Dec 15 15:32:03 2018

# Starting class: TestProtocol

not ok 1 TestProtocol.test_brk_list_travel_success

# cases.lua:117: expected: 200, actual: 406

# Ran 1 tests in 0.016 seconds, 0 successes, 1 failure

测试失败，我们要检查下log，查看/var/log/brk.log，发现错误

从log上看是数据库没有创建，所以如果你还没有学习数据库，那先学习下mysql再继续搞这个项目。
