Greetings,
  I cannot compile my Boost C++ code.

  Initially, it complains of “undefined reference”. When I try to
resolve this by including the library, I get the "/usr/bin/ld: cannot
find -lboost_system" error.

  From the Terminal:
Go Bears >echo $LD_LIBRARY_PATH
/usr/lib/libboost_system.so
Go Bears >make all
g++ -L/usr/lib -lboost_system get_sys_info.cpp
/usr/bin/ld: cannot find -lboost_system
collect2: ld returned 1 exit status
make: *** [all] Error 1

Do you know what stupid mistakes did I make?

>From my Makefile:
all:
    g++ -L/usr/lib -lboost_system get_sys_info.cpp
    ./a.out

  Thank you so much, and have an awesome day!
