hm. But I have only one main target (a lib). The cited page says

<quote>
By default, Boost.Build handles such dependencies within one main
target. For example, assume that main target "app" has two sources,
"app.cpp" and "parser.y". The latter source is converted into "parser.c"
and "parser.h". Then, if "app.cpp" includes "parser.h", Boost.Build will
detect this dependency. Moreover, since "parser.h" will be generated
into a build directory, the path to that directory will automatically
added to include path.
</quote>

That is 'exe app : app.cpp parser.y ;'.
 From parser.y the tool creates parser.h and then app is built using
app.cpp and parser.h.

Doesn't this mean that my jamfile should work? The only difference I can
see is that I only create a *.h file from *.idl instead of a *.h and a
*.cpp file.
