[ECOS] pkgconf.tcl GUI mode

[ECOS] pkgconf.tcl GUI mode

[Dave Vogel]

I was noticing that the pkgconf.tcl has GUI code for configuring the
eCos OS on a Unix box (by setting the variable gui_mode, and using
"wish" to run the script).  Is there a reason this is not documented (or
did I overlook something).  I was under the impression that the only gui
method to configure eCos was with the NT configtool.

On second look, maybe I know - it only has limited configuration
capability.

Exactly; it was done as an experiment to see how such a thing might look,
it's not supported in the slightest, &c &c...

I sometimes use it just 'cos it's a quicker way to disable everything
except the kernel (and maybe uITRON) - when I'm working on those kinds of
pieces of work.  Saves buildtime I mean.

As Huge has already pointed out the GUI code was added as an
experiment, during a Sunday afternoon if I remember correctly. It
provides very little functionality, basically just the ability to
select the target and the packages you want. The Windows tool provides
much more functionality, but of course implementing that took a bit
longer than an afternoon.

It was decided not to continue with the pkgconf GUI, thus saving us
from having to maintain and more importantly document it. In addition
it might have caused some confusion between the full configuration
tool and pkgconf.tcl, which we wanted to avoid. The code has been left
in because some people have found it useful on occasion, but there is
no guarantee it still works.

To actually enable the code, you would need to apply a small patch
to the released version of pkgconf.tcl. In addition you would need to
run pkgconf.tcl using the wish interpreter rather than tclsh. For the
current anonymous CVS sources the patch below should work. For the
release version the line numbers may be slightly out.
