Is it possible to use incr-tcl when working with tcl version 8.4.19? Which include packages are required? Until now we used Active-Tcl version 8.6, which came with incr-tcl built-in. Now we need to support stations that only have version 8.4.19 installed, and I want to know whether there's a technological roadblock or if it's just a matter of installing and referencing additional packages.

There might be other problems: no `{*}`, no `dict` and many other things are missing in Tcl 8.4. – Johannes Kuhn Apr 10 '13 at 12:47

It's most certainly possible to have [incr Tcl] working with the Tcl 8.4 series.
bash$ tclsh8.4
% puts [info patchlevel]
8.4.7
% package require Itcl
3.3
% puts $itcl::patchLevel
3.3b1
You might prefer a slightly different version, but that combination works on my system (OSX Leopard).

@johannes thank you - where can I find a reference to what is supported and what is not? – dzisner Apr 10 '13 at 13:48
