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

Do you mean Boost C++ code, thus building Boost libraries, or you mean your code that *uses* Boost libraries? Unclear.

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.

So, looks like the former, you are trying to use the libraries.

From the Terminal: Go Bears >echo $LD_LIBRARY_PATH /usr/lib/libboost_system.so

Where do you get this from?

"LD_LIBRARY_PATH, which is a colon-separated list of directories" [1]

Go Bears >make all g++ -L/usr/lib -lboost_system get_sys_info.cpp

Have you installed it first?

sudo apt-get install libboost-system-dev
