Hello. I am currently trying to launch xschem using https://github.com/iic-jku/osic-multitool and am getting the following error.

hayato@DESKTOP-931VA3D:~$ xschem
cd caravel_user_project_analog

^CUse 'exit' to close the program

         : invalid command name "tk_messageBox"

What I worked on:

cd osic-multitool/

export NGSPICE_VERSION=38

./iic-osic-setup.sh

cd

source iic-init.sh

There is no error on the way, but when xschem is executed after this, the above error appears. If anyone knows how to solve this problem, we would appreciate it if you could let us know.

I mean I cant help you with that problem, but why arent you useing the docker container? Everything is already set up there... I think its called iic-osic-tools...

It looks like only

tcl

is installed and not

tk

. The errors are due to

wm

,

tk_messageBox

,

image

commands not recognized. These are tk commands. Install tk8.6 package (

sudo apt install tk8.6

) To quickly check if

tk

is installed try to run the tk shell,

wish

, or

wish8.6

. If it tells command not found then tk is missing on the system.

Thank you for your comment. I checked and tk8.6 was already installed. We will try to use docker.
