Permission denied when creating /etc/astra-sim directory

[Dreampop0215]

Hi,

When running the command ./scripts/build.sh -c analytical, I encountered the following error:

mkdir: cannot create directory ‘/etc/astra-sim’: Permission denied

It seems like the script is trying to create a directory under /etc/(presumably to store configuration files?). However, as a regular user, I don't have permission to write to /etc/, so the directory creation failed.
That said, the overall build command still seemed to complete successfully.

My questions are:​

1. Was the intention of the script to write configuration files or create directories under /etc/astra-sim?
2. Since the directory creation failed due to permission issues, could this lead to any missing functionality or misconfiguration later on?
3. Is there a recommended way to run this script (e.g., specifying a different config location, or using sudo) to avoid this issue while still ensuring everything works as intended?

Thanks in advance for your help!

do you have such problem when running ns3 simulation, it didn't even begin before segmatation falut. However ns3-alibaba seems to have a different branch compared to the master branch in SimAI.

I solved this issue like this:

Run:

grep -n "/etc/astra-sim" astra-sim-alibabacloud/build.sh

Output:

6:SIM_LOG_DIR=/etc/astra-sim

Modify SIM_LOG_DIR, for example:

sed -i '6c SIM_LOG_DIR='"$HOME"'/.config/astra-sim' astra-sim-alibabacloud/build.sh
mkdir -p "$HOME/.config/astra-sim"
