The BlueCat envorinment is its own little world, meant to make it exceptionally easy to build things for the target. Because of this, they violate a few expectations for a cross-compile environment. One of these is that their compiler looks for headers in the wrong place for boost.
What I am trying to figure out is how to tell the boost build process to append a path onto the list of include search paths.
setting HDRS, either in the environment or on the bjam invocation line doesn't seem to help. I guess it's not propagating down?
Thanks in advance for your advice.
Use the BUILD environment variable, either: bjam -sBUILD="<include>mypath" or if the options you need are more obsure than usual then: bjam -sBUILD="<cxxflags>--some-option" Will inject --some-option directly onto the compiler command line. John.
