Francesco,

you're in the wrong list. Try http://www.boost.org/more/mailing_lists.htm#jamboost

Greetings All,

I have done some web searching (http://www.boost.org/tools/build/jamsrc/ etc), and also searching the list via Gmane and could not find a satisfactory result to the following questions?: When should you edit the boost-build.jam

The former points to the Boost.Build installation

instead of jamrules?

The latter contains whatever definitions you need locally to your project.

Do you need a jamrules in the root directory of every project?

Yes.

You just need a boost-build.jam in the root directory of your project or somewhere further up the hierarch?

Further up is fine. I put one above all my projects.

What are the purposes of the three different files?

Three?

Is the jamfile to specify depencies and what the target executable is?

Yes.

Is the jamrules file only for setting parameters such as TOOLS and PYTHONROOT so they don't have to be entered every time on the command line?

Stuff like that, yeah.

Is the only reason to have a boost-build.jam to point to tools/build/v1 subdirectory?

Yeah.

If someone could point me to another reference to answer these questions or answer them outright I would greatly appreciate it.
