在導致未定義符號錯誤的示例代碼上使用Boost庫？

我想運行一個example codeg++ reference_counted.cpp，但該程序產生的錯誤在導致未定義符號錯誤的示例代碼上使用Boost庫？

Undefined symbols for architecture x86_64: 
    "boost::system::system_category()", referenced from: 
     __static_initialization_and_destruction_0(int, int) in ccD1hl7z.o 
     boost::system::error_code::error_code() in ccD1hl7z.o 
     boost::asio::error::get_system_category() in ccD1hl7z.o 
    "boost::system::generic_category()", referenced from: 
     __static_initialization_and_destruction_0(int, int) in ccD1hl7z.o 
ld: symbol(s) not found for architecture x86_64 
collect2: error: ld returned 1 exit status

運行brew doctor產生以下警告，但目前還不清楚是什麼原因造成的失敗。這怎麼解決？

Warning: "config" scripts exist outside your system or Homebrew directories. 
`./configure` scripts often look for *-config scripts to determine if 
software packages are installed, and what additional flags to use when 
compiling and linking. 

Having additional scripts in your path can confuse software installed via 
Homebrew if the config script overrides a system or Homebrew provided 
script of the same name. We found the following "config" scripts: 

    /opt/local/bin/curl-config 
    /opt/local/bin/freetype-config 
    /opt/local/bin/icu-config 
    /opt/local/bin/libpng-config 
    /opt/local/bin/libpng15-config

    /opt/local/bin/python-config 
    /opt/local/bin/python2.7-config 
    /opt/local/bin/xml2-config 

Warning: /Library/Frameworks/Mono.framework detected 
This can be picked up by CMake's build system and likely cause the build to 
fail. You may need to move this file out of the way to compile CMake. 

Warning: You have MacPorts or Fink installed: 
    /opt/local/bin/port 

This can cause trouble. You don't have to uninstall them, but you may want to 
temporarily move them out of the way, e.g. 

    sudo mv /opt/local ~/macports 

Warning: Unbrewed dylibs were found in /usr/local/lib.

Warning: You have unlinked kegs in your Cellar 
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on 
those kegs to fail to run properly once built. Run `brew link` on these: 

    python 

Warning: You have uncommitted modifications to Homebrew 
If this a surprise to you, then you should stash these modifications. 
Stashing returns Homebrew to a pristine state but can be undone 
should you later need to do so for some reason. 
    cd /usr/local/Library && git stash && git clean -d -f 

Warning: Some directories in your path end in a slash. 
Directories in your path should not end in a slash. This can break other 
doctor checks. The following directories should be edited: 
    /usr/local/facebook/arcanist/bin/ 

Warning: Homebrew's sbin was not found in your PATH but you have installed

您需要將您的應用程序boost_system庫鏈接。我覺得ASIO還需要boost_thread，因此，在總結它：
