Boost.Asio安装问题 [英] Boost.Asio installation issue

问题描述

我已经使用bjam install安装了boost库，但是当我编译程序时:

i have already installed boost libraries with bjam install, but when i'm compiling programme:

#include boost/asio.hpp

int main()
{
 return 0;
}

发生此类错误:

/tmp/ccVR3eeF.o: In function `__static_initialization_and_destruction_0(int, int)':
sda.cpp:(.text+0x52): undefined reference to `boost::system::generic_category()'

collect2: ld returned 1 exit status

我该怎么办?我该如何建立这些库?

what do i have to do? how can i build those libraries?

推荐答案

Boost.Asio也需要Boost.System库.您需要在链接器命令行中添加-lboost_system.

Boost.Asio requires the Boost.System library as well; you need to add -lboost_system to your linker command line.

向程序添加功能时，可能还需要Boost的其他部分，例如Boost.Thread，Boost.Date_Time等.参见 http://www.boost.org/doc/libs/1_46_1/doc/html/boost_asio/using.html 了解详情.

As you add features to your program, you might also need other parts of Boost, like Boost.Thread, Boost.Date_Time, and so on. See http://www.boost.org/doc/libs/1_46_1/doc/html/boost_asio/using.html for details.
