c++ - Boost库在ubuntu上产生错误

Question

我正在尝试编译从 here 获得的代码.我已经使用 sudo apt-get install libboost-all-dev 在 Ubuntu 上安装了 boost 库。安装很顺利，我能够编译所有示例。然后我尝试了 example found here使用 boost::asio 和谷歌 Protocol Buffer 。 Vim 中的 Clang_complete 开始给我一些奇怪的问题，这让我相信我需要更新 boost 的版本。 (从存储库安装 1.46)。

我意识到 Ubuntu 存储库使用的是旧版本的 Boost，所以我决定自己下载并安装它。我用了this安装库的教程(用 ./b2 替换 ./bjam)。这是问题开始的时候。下面的代码在 boost 的 Synaptic 安装中运行良好，但在手动构建之后我遇到了很多错误。我在想缺少了什么，但我不确定我是如何弄清楚我需要安装什么的。

代码如下所示:

#include <boost/asio.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/thread.hpp>
#include <boost/thread/mutex.hpp>
#include <boost/bind.hpp>
#include <iostream>

boost::mutex global_stream_lock;

void WorkerThread( boost::shared_ptr< boost::asio::io_service > io_service )
{
global_stream_lock.lock();
std::cout << "[" << boost::this_thread::get_id()
    << "] Thread Start" << std::endl;
global_stream_lock.unlock();

io_service->run();

global_stream_lock.lock();
std::cout << "[" << boost::this_thread::get_id()
    << "] Thread Finish" << std::endl;
global_stream_lock.unlock();
}

size_t fib( size_t n )
{
if ( n <= 1 )
{
    return n;
}
boost::this_thread::sleep( 
    boost::posix_time::milliseconds( 1000 )
);
return fib( n - 1 ) + fib( n - 2);
}

void CalculateFib( size_t n )
{
global_stream_lock.lock();
std::cout << "[" << boost::this_thread::get_id()
    << "] Now calculating fib( " << n << " ) " << std::endl;
global_stream_lock.unlock();

size_t f = fib( n );

global_stream_lock.lock();
std::cout << "[" << boost::this_thread::get_id()
    << "] fib( " << n << " ) = " << f << std::endl;
global_stream_lock.unlock();
}

int main( int argc, char * argv[] )
{
boost::shared_ptr< boost::asio::io_service > io_service(
    new boost::asio::io_service
);
boost::shared_ptr< boost::asio::io_service::work > work(
    new boost::asio::io_service::work( *io_service )
);

global_stream_lock.lock();
std::cout << "[" << boost::this_thread::get_id()
    << "] The program will exit when all work has finished."
    << std::endl;
global_stream_lock.unlock();

boost::thread_group worker_threads;
for( int x = 0; x < 2; ++x )
{
    worker_threads.create_thread( 
        boost::bind( &WorkerThread, io_service )
    );
}

io_service->post( boost::bind( CalculateFib, 3 ) );
io_service->post( boost::bind( CalculateFib, 4 ) );
io_service->post( boost::bind( CalculateFib, 5 ) );

work.reset();

worker_threads.join_all();

return 0;
}

现在，当我尝试编译代码时，出现以下错误:

命令行: g++ -o example3a example3a.cpp -lboost_system -lboost_thread编译器输出:

Answer 1

好的，我让它工作了。我正在按照说明 here但以下似乎搞砸了安装:

/bootstrap.sh --exec-prefix=/usr --libdir=/usr/lib --includedir=/usr/include

(我注意到旧版本的 boost 在/usr/include 和/usr/lib 中。这就是为什么我添加了上面的选项。:(

相反，我简单地尝试了这个:

./bootstrap.sh
./b2
sudo ./b2 install

现在示例编译。
