与Boost.build和对升压

Question

链接建设成为我开始有增强的lib项目，看来我的设置是不工作：

main.cpp中：

#include <boost/asio.hpp> 
int main(int argc, char* argv[]) 
{ 
    boost::asio::io_service io_service_; 
    return 0; 
} 

的Jamfile：

exe node 
: main.cpp ; 

bjam会产生：

...updating 2 targets...

看来，bjam正确地找到头，但不是库。 于是，我就告诉bjam，哪里找升压：

的Jamfile：

use-project /boost : /usr/lib/boost ; 

exe node 
    : main.cpp 
     /boost//system 
    ; 

但bjam的，现在将产生：

/usr/share/boost-build/build/project.jam:270: in find-jamfile from module project 
error: Unable to load Jamfile. 
error: Could not find a Jamfile in directory '/usr/lib/boost'. 
error: Attempted to find it with pattern '[Bb]uild.jam [Jj]amfile.v2 [Jj]amfile [Jj]amfile.jam'. 
error: Please consult the documentation at 'http://www.boost.org'.

/usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build from module 
/usr/share/boost-build/boost-build.jam:1: in module scope from module 

它unerstand说的bjam要重建提振，这就是为什么它是在/usr/lib/boost中寻找Jamfile。

有什么遗漏吗？ 我怎么能告诉bjam链接的缺失库在哪里？

有些时候以前，我用

LINKLIBS = -lboost_system -lboost_filesystem ; 

但我不知道怎么翻译这个为Boost.build V2。

谢谢。

最后，我得到了解决方案。 我预计能够采取多个库，但我错了。

这里是修复，我改变了我的Jamfile到：

exe node 
: main.cpp 
: <linkflags>-lpthread 
    <linkflags>-lboost_system 
;
