Hello,

     I have been banging
my head on this for a couple too long so I need some help.  Here is
the concept of what I am doing:

I use an intermediate language(.idl)
to generate 2 cpp and 2 hpp files.  I have an exe(idlcompiler) (that
I build to do so) that take the .idl and 

generate the cpp and hpp files.



What I want to have:

     -If change one idl,
I want to regenerate its hpp/cpp files.

     -If I change the
source code of the exe, I want to rebuild that exe and then I want all
hpp/cpp to be regenerated for their idls.



I ll post part of my jambase that I
find relevent.  Feel free to ask for more if you think it is important



Thank you for any information that can
help me make this works !
