I am trying to compile the multiple_sources.cpp to compile on my computer. I am running Xubuntu Lucid Lynx fully updated.
It will compile without issue with g++ -c multiple_sources.cpp
but when I try to link and make an exectuable with g++ multiple_sources.o
I get:
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+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)'
...
et cetera ad nauseum.
I do have the library installed:
>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 root 26 2010-04-09 00:57 /usr/lib/libboost_program_options-mt.a -> libboost_program_options.a
lrwxrwxrwx 1 root root 34 2010-04-09 00:57 /usr/lib/libboost_program_options-mt.so -> libboost_program_options.so.1.40.0
lrwxrwxrwx 1 root root 34 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
After reading the g++ man page, I have also tried:
g++ -llibboost_program_options multiple_sources.cpp
g++ -llibboost_program_options.a multiple_sources.cpp
g++ -llibboost_program_options.so multiple_sources.cpp
- and all of the above with
-L/usr/lib
before the-l
They all fail with a variation on:
/usr/bin/ld: cannot find -llibboost_program_options.so
collect2: ld returned 1 exit status
What am I doing wrong?
