Hi All,

I am working on a EDA tool which is built on TCL 8.3 platform. I need to upgrade the platform to TCL 8.6.

Is it proper to move directly from 8.3 to 8.6 version? Or should I upgrade to TCL 8.5 as TCL 8.6 is still beta version.

Please suggest me precautions.

Please point me to documentation/User guide related to this.

Thanks for help,
Divyesh

Tcl 8.6.1 is now the current stable version so it probably make sense to move to that, see http://tcl.tk/software/tcltk/8.6.html

Tcl 8.6 is an improvement with extra functionalities and should work with unchanged code. Tk is more a problem with unsupported functions that has been replaced by other commands, just see the file "unsupported.tcl" in 8.6 installation. The binary extensions are more a problem for instance BLT needs to be replaced, Tcom is no more supported, not all extensions have 64-bit version .... As about an EDA software, I suspect you don't have only Tcl or Tcl/Tk under the hood !

Tcl/Tk 8.6.1 is not in beta and is quite robust and has nice improvements for EDA such as text with angle in the text widget... If you need Tk.

Regards,

Olivier

Hi, Olivier
you are right, actually this tool is built using C++, TCL and many other things under the hood.
So i need to know what are the things should I take care about after migration, to avoid later surprises in the behavior of the tool

Thanks for your help,
