And, building an application dependent on Boost completes without err. Boost doesn't seem to have a package for my distro of Linux so I am having to build from source. I have built Boost 1.45 and 1.42 with the same effect as follows: After building Boost, and subsequently attempting to build the application dependent on Boost, I receive an error: $ g++ -ggdb -g -O2 -lssl -lboost_system-mt -o /usr/bin/ld: cannot find -lboost_system-mt I built Boost according to the instructions at [http://www.boost.org/doc/libs/1_45_0/more/getting_started/unix-variants.html] as I understand them: $ ./bootstrap.sh --prefix=/usr/local $ ./bjam install This fills /usr/local/include/ with Boost's .hpp files and /usr/local/lib/ with many libboost_xxxxxxx files. Nowhere in /usr/local/lib/ is any file ""*-mt*"", let alone a ""boost_system-mt*"" anywhere on my system. Why is this not working for me?"
