Re: Link Tcl to a different tcl.dll on Windows

$ENV{'PERL_TCL_DL_PATH'} = $pathTclDLL;

That line (from the "update" section of your post) looks dubious to me.
It sets:

$ENV{'PERL_TCL_DL_PATH'} = $Bin . "\\tcltk2\\bin\\tcl86.dll";
but you probably want
$ENV{'PERL_TCL_DL_PATH'} = $Bin . "\\tcltk2\\bin";
[download]

I suspect that the updated script works because $ENV{PATH} provides everything that's needed, and that you could remove all lines that mention $pathTclDLL - and the script would still work.

Cheers,
Rob

~~You are right, Rob. It works. However, now~~ No, this does not solves the issue. I am more confused than before. In any post I have seen (mainly dealing with Tkx which should rely on Tcl.pm) I have always seen `$ENV{'PERL_TCL_DL_PATH'}` used with dll. For now, it works only with the script I proposed above.

That feature is for packagers like PAR/pp. Not for mixing incompatible bin/tcl	[reply]
