I get the following error when I cd to BOOST_ROOT/doc and run ../bjam My ~/user-config.jam looks fine. I pasted it bellow the error. Does anyone know how to fix this? I have spent a great deal of time trying to fix this. It looks like the doxygen.jam in the boost_1_63_0/tools/build/src/tools directory does not like the syngax of the doxygen rule in ~/user-config.jam. ---------------------------------------------------------------------------------------------------------------------------------- Building the tti docs with automatic index generation disabled.
