Java 語言，把并發(fā)機(jī)制包含在核心語言中，因?yàn)镴ava語言具有平臺(tái)無關(guān)性。而C沒有并發(fā)機(jī)制，C++標(biāo)準(zhǔn)中也因此并沒有納入并發(fā)機(jī)制。我們?cè)趙indows平臺(tái)下開發(fā)c++，當(dāng)使用并發(fā)機(jī)制時(shí)往往使用的SDK win32 api。在《c++編程思想》一書中，作者提供了一種開源的跨平臺(tái)的高級(jí)面向?qū)ο蟮木€性和sycnchronization 庫 -- ZThread 。

ZThread庫的主頁：http://zthread.sourceforge.net

上面的網(wǎng)站打不開。可以用下面到地址來下載。

源碼Zthread下載地址: http://prdownloads.sourceforge.net/zthread/ZThread-2.3.2.tar.gz

一、在linux 下編譯

??????? 1.下載保存 文件到 /usr/local/src

???????? 2. 解壓

????????? ?? cd /usr/local/src

???????????? tar -zxvf ZThread-2.3.2.tar.gz

??????? 3.編譯安裝

???????????? cd ZThread-2.3.2

???????????? ./configure --prefix=/usr/local/ZThread

??????????? 如果在./configure時(shí)遇到錯(cuò)誤：

??????????? error: C++ compiler cannot create executables?

??????????? yum install gcc-c++

????????? 然后繼續(xù):

?????????? make

??????????? 在make時(shí)遇到錯(cuò)誤：

??????????? ../include/zthread/Guard.h: In destructor 'ZThread::Guard<LockType, LockingPolicy>::~Guard()':

??????????? ../include/zthread/Guard.h:494: error: there are no arguments to 'isDisabled' that depend on a template parameter, so a declaration of 'isDisabled' must be available

?????????? 只需?先export CXXFLAGS=-fpermissive，然后再執(zhí)行

????????? ./configure --prefix=/usr/local/ZThread

????????? make

????????? make install

二、linux下使用

? ? ? ? 1.寫文件 ???? zthread0.h ???

#ifndef LIFT_OFF_H #define LIFT_OFF_H #include <iostream> #include "zthread/Runnable.h" using namespace std;class LiftOff : public ZThread :: Runnable{int countdown;int id; public:LiftOff(int count,int ident=0):countdown(count),id(ident){}~LiftOff(){cout << id << "completed " << endl;}void run(){while(countdown--){cout << id << ":" << countdown << endl; }cout << id << " lift off " << endl;} }; #endif
BasicThreads.cpp

#include "zthread0.h" #include "zthread/Thread.h" using namespace std; using namespace ZThread;int main(){try{Thread t(new LiftOff(10),true);cout << "Waiting for LiftOff " << endl;}catch(Synchronization_Exception& e){cerr << e.what() << endl;} } ///:~ ????? 2.編譯鏈接加入ZThread庫

????????

gcc BasicThreads.cpp -L /usr/local/ZThread/lib -I /usr/local/ZThread/include -lstdc++ -lZThread
?????? 注意 -L 后面接ZThread的安裝路徑/lib

????? 要加入-lstdc++，否則會(huì)有如下錯(cuò)誤：??

??? (.text+0x3a29): undefined reference to `std::basic_ostream<char, std::char_traits<char>

?????? 要加入-lZThread，相當(dāng)于加入附加依賴項(xiàng)ZThread.lib，否則會(huì)有如下錯(cuò)誤：

???? (.text+0xd1):XX.cpp: undefined reference to `ZThread::Thread::Thread(ZThread::Task const&, bool)'

???? 3.運(yùn)行

????? ./a.out

????? 可能會(huì)有錯(cuò)誤：error while loading shared libraries: libZThread-2.3.so.2: cannot open shared object file: No such file or directory

?????? 將libZThread-2.3.so.2拷貝到/usr/lib下

????? 如： cp /usr/local/ZThread/lib/libZThread-2.3.so.2 /usr/lib

????? 然后運(yùn)行OK ，輸出如下所示：

Waiting for LiftOff 0:9

0:8
0:7
0:6
0:5
0:4
0:3
0:2
0:1
0:0
0 lift off
0completed
????

???????

總結(jié)
