Hello everyone I am facing an issue in the installation of xschem. I am following https://ordinary-cough-d7f.notion.site/Installing-Skywater-a2c1dac4ec21430eb25e4116724a94d4. Can someone help me out. I am a beginner in using linux based systems.

You need to install the C compiler to build the program. If you have an Ubuntu system the command is

sudo apt-get install gcc

. Also check this manual page to install all required packages first.

Thank you so much for your help @Stefan Schippers
