From reading the documentation on boost.org, I have gotten the impression I don't need to set $BOOST_BUILD_PATH and $BOOST_ROOT.

Correct. ... http://www.boost.org/tools/build/jam_src/#jambase_replacement

describes the file that bjam expects to see when it starts up. You might also drop a Jamrules file in the root directory of your own Boost.Build project (if you use bjam for your own project) that contains:

project boost : path/to/boost_1_31_0 ;

I set the BOOST_ROOT to the value that I thought it should have

Whatever. You don't need to set that variable, provided you set up boost-build.jam.

and was able to run bjam on a very simple project. I then put the value of BOOST_ROOT in a Jamrules file in the same directory and unset the BOOST_ROOT variable. I attempted to run bjam again and was informed that it was unable to find "boost-build.jam"

Which is why I pointed you at http://www.boost.org/tools/build/jam_src/#jambase_replacement The most general approach is to create a boost-build.jam

This is the entire content of the directory:

//main.cc #include <iostream>

int main() { std::cout << "Hello Boost Jam!\n"; }

# Jamfile project-root ; exe hello : main.cc ;

#Jamrules project boost : /<path to>boost/1_31_0 ;

Have I done something wrong?

Add a boost-build.jam somewhere in your directory or a parent: boost-build path/to/boost_1_31_0 ; -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
