What you give "-lboost_system", the linker would search for
libboost_system.so file.  Is there such a file?  It most probably
would be a soft link to one of the shared library that you mentioned
above.  Also try providing the path to the shared library will the -L
option.

$ ls /usr/local/lib/libboost_system.so /usr/lib/libboost_system.so
# one of them should be there
$ g++ timer3.cpp -L/usr/local/lib -L/usr/lib -lboost_thread -lboost_system

Hope that helps.

Rgds,
