I have recently upgraded from Boost 1.54 to 1.57. But when I look in my lib directory where all my boost library files are located, I do not see libboost_log.so
I ran ./bootstrap.sh --show-libraries to see what should get installed and I received the following:
pdl@pdl-VirtualBox:~/Downloads/boost_1_57_0$ ./bootstrap.sh --show-libraries Building Boost.Build engine with toolset gcc... tools/build/src/engine/bin.linuxx86_64/b2 The following Boost libraries have portions that require a separate build and installation step. Any library not listed here can be used by including the headers only. The Boost libraries requiring separate building and installation are: - atomic - chrono - container - context - coroutine - date_time - exception - filesystem - graph - graph_parallel - iostreams - locale - log - math - mpi - program_options - python - random - regex - serialization - signals - system - test - thread - timer - wave pdl@pdl-VirtualBox:~/Downloads/boost_1_57_0$ I need to install the log library. It is a separate library that I downloaded separately as shown here:

I've been through the documents, Getting Started Guide, and looked on-line for how to install these separate libraries but I'm just not getting it.
