Describe the bug
When running the opnelane flow, it creates a bunch of directories and files. The permission to create them is denied.

To Reproduce
Steps to reproduce the behavior:

  1. run start_x.sh script
  2. Go to the openlane directory.
  3. Run "make mount"
  4. Run "./flow.tcl -design spm -overwrite"

Expected behavior
The entire openlane flow should run.

Environment:

  • OS: Linux - Ubuntu 22.04
  • Operating mode: X11
  • Version tag: latest

Additional context
When running a container with "start_shell.sh", the default user is root. But while running a container with "start_x.sh", the default user is Inside the container is "designer". The openlane flow doesn't run inside the container started by 'start_x.sh' script, but for the other one it runs. I need to use the GUI of klayout, so I need to run the container with "start_x.sh".

@Satvik3799 When you use the IIC-OSIC-TOOLS container, OpenLane is already right there, you don't need to start a container for OpenLane. So what you need to do is

  1. Run start_x.sh
  2. Copy the spm example to /foss/designs
  3. Run flow.tcl -design spm -overwrite

It's working. But since I am running things as the user "Designer", how do I become root in the new terminal that is opened when I run the start_x.sh script.

You can do CONTAINER_USER=0 CONTAINER_GROUP=0 ./start_x.sh, then you are root inside the container. Use with care.
