Hello all,
I am new to boost.

I try to use some boost files in my program, but I have trouble with some
of them.
For example
compiling the following program

#include <boost/log/expressions/formatters/date_time.hpp>

int main()
{
  return 0;
}

with the command
g++ -std=c++11 test.cpp -o main -I/home/user101/boost/ -L/home/user101/boost
 I have a message like the following

/tmp/ccm6UOud.o: In function `boost::system::generic_category()':
test.cpp:(.text._ZN5boost6system16generic_categoryEv[_ZN5boost6system16generic_c
                                                       ategoryEv]+0x5):
undefined reference to `boost::system::detail::generic_category
                                             _ncx()'

I also tried to append -lboost_system in the command, but I take back the
following message:
/usr/bin/ld: cannot find -lboost_system
collect2: error: ld returned 1 exit status

Could you please guide me with that? I use boost_1_67 if that makes any
difference (which I do not think so).

Thanks,
Antonis
