連結時找不到C庫,錯誤編譯`boost :: program_options`的例子

在我的電腦上編譯.我正在執行Xubuntu Lucid Lynx全面更新.

它將使用g -c multiple_sources.cpp編譯沒有問題,但是當我嘗試連結並使用gulti_sources.o進行編寫時,我得到：

multiple_sources.cpp:(.text+0x3d): undefined reference to `boost::program_options::options_description::m_default_line_length'
multiple_sources.cpp:(.text+0x87): undefined reference to `boost::program_options::options_description::options_description(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)'
multiple_sources.cpp:(.text+0x15a): undefined reference to `boost::program_options::options_description::add_options()'
multiple_sources.cpp:(.text+0x17b): undefined reference to `boost::program_options::options_description_easy_init::operator()(char const*, char const*)'
multiple_sources.cpp:(.text+0x193): undefined reference to `boost::program_options::options_description_easy_init::operator()(char const*, char const*)'
multiple_sources.cpp:(.text+0x1af): undefined reference to `boost::program_options::options_description_easy_init::operator()(char const*, boost::program_options::value_semantic const*, char const*)'
multiple_sources.cpp:(.text+0x1eb): undefined reference to `boost::program_options::options_description::m_default_line_length'
multiple_sources.cpp:(.text+0x252): undefined reference to `boost::program_options::options_description::options_description(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)'
...

等等噁心.

我有圖書館安裝：

>ls -l /usr/lib/libboost_program_options*
-rw-r--r-- 1 root root 640800 2010-03-31 21:19 /usr/lib/libboost_program_options.a
lrwxrwxrwx 1 root root26 2010-04-09 00:57 /usr/lib/libboost_program_options-mt.a-> libboost_program_options.a
lrwxrwxrwx 1 root root34 2010-04-09 00:57 /usr/lib/libboost_program_options-mt.so -> libboost_program_options.so.1.40.0
lrwxrwxrwx 1 root root34 2010-04-09 00:57 /usr/lib/libboost_program_options.so -> libboost_program_options.so.1.40.0
-rw-r--r-- 1 root root 289336 2010-03-31 21:19 /usr/lib/libboost_program_options.so.1.40.0

閱讀g手冊頁後,我也試過：

> g -llibboost_program_options multiple_sources.cpp

> g -llibboost_program_options.a multiple_sources.cpp

> g -llibboost_program_options.so multiple_sources.cpp

>和所有上面的-L /usr/lib之前的-l

他們都失敗了,變化如下：

/usr/bin/ld: cannot find -llibboost_program_options.so
collect2: ld returned 1 exit status

我究竟做錯了什麼？
