1、简介
Thrift是Facebook的一个开源项目,主要是一个跨语言的服务开发框架。它有一个代码生成器来对它所定义的IDL定义文件自动生成服务代 码框 架。用户只要在其之前进行二次开发就行,对于底层的RPC通讯等都是透明的。目前它支持的语言有C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk, and OCaml.
环境:
OS:Ubuntu 12.04.1 LTS
内核:3.2.0-33-generic-pae
2、下载thrift
wget http://labs.renren.com/apache-mirror//thrift/0.9.0/thrift-0.9.0.tar.gz(下载版本为0.9.0) 3、安装依赖包
sudo apt-get install libboost-dev libboost-test-dev libboost-program-options-dev libevent-dev automake libtool flex bison pkg-config g++ libssl-dev ant 4、解压
tar -zxvf thrift-*.tar.gz 进入目录cd thrift-*
5、安装编译
./configure
make
sudo make install 6、安装测试
安装后thrift -version查看版本信息,表示安装成功。
Thrift version 0.9.0
7、自带例子测试
thrift中有自带的例子,在tutorial目录内,我们测试其中cpp的例子。
进入tutorial目录,shared.thrift和tutorial.thrift是接口定义文件。
执行 thirft -r --gen cpp tutorial.thrift,可以生成gen-cpp目录,这是thrift编译器自动生成的代码。
然后进入tutorial/cpp目录,执行make,生成可执行文件。不过make之后会有各式各样的错误,我们一一改正。
8、make之后可能出现的错误及改正
(1) 错误1:非常多的错误,找到第一个错误是
大意是/usr/local/include/thrift/concurrency/Thread.h中的pthread_self、pthread_equal等没有声明,搜了一下好像很少有人遇到过这个问题。不过不打紧,错误的意思可以理解,搜到pthread_self、pthread_equal对应的头文件是#include <pthread.h>,加到那个Thread.h中就好了。
(2)错误2:/usr/local/include/thrift/protocol/TBinaryProtocol.tcc:147:35: 错误: ‘htons’的实参不依赖模板参数,
解决:‘htons’的声明必须可用[-fpermissive],则修改Makefile,加上编译选项-DHAVE_NETINET_IN_H
修改后的Makefile(部分)
server: CppServer.cpp
g++ -DHAVE_NETINET_IN_H -o CppServer -I${THRIFT_DIR} -I${BOOST_DIR} -I../gen-cpp -L${LIB_DIR} -lthrift CppServer.cpp ${GEN_SRC}
client: CppClient.cpp
g++ -DHAVE_NETINET_IN_H -o CppClient -I${THRIFT_DIR} -I${BOOST_DIR} -I../gen-cpp -L${LIB_DIR} -lthrift CppClient.cpp ${GEN_SRC}
(3)错误3:仍然是非常多的错误

修改后的Makefile
BOOST_DIR = /usr/local/boost/include/boost-1_33_1/
THRIFT_DIR = /usr/local/include/thrift
LIB_DIR = /usr/local/lib
GEN_SRC = ../gen-cpp/SharedService.cpp ../gen-cpp/shared_types.cpp ../gen-cpp/tutorial_types.cpp ../gen-cpp/Calculator.cpp
default: server client
server: CppServer.cpp
g++ -DHAVE_NETINET_IN_H -o CppServer -I${THRIFT_DIR} -I${BOOST_DIR} -I../gen-cpp -L${LIB_DIR} CppServer.cpp ${GEN_SRC} -lthrift
client: CppClient.cpp
g++ -DHAVE_NETINET_IN_H -o CppClient -I${THRIFT_DIR} -I${BOOST_DIR} -I../gen-cpp -L${LIB_DIR} CppClient.cpp ${GEN_SRC} -lthrift
clean:
$(RM) -r CppClient CppServer
9、运行
再次执行make,运行成功,得到可执行程序CppServer和CppClient
在两个窗口依次运行./CppServer和./CppClient
输出如下:
$ ./CppClient
ping()
1+1=2
InvalidOperation: Cannot divide by 0
15-10=5
Check log: 5
$ ./CppServer
Starting the server...
ping()
add(1,1)
calculate(1,{4,1,0})
calculate(1,{2,15,10})
