So I've been working to build Android AOSP project. I followed the guidelines on the official documentation (https://source.android.com/setup/build/downloading). After several tries, i always got the below error stack trace from the terminal. I'm trying to build 'aosp_coral-userdebug'. Another thing I noticed is that, if I use another combo from the menu, I also get another form of error with 'ninja'. Help please!!!
12:09:31 You are building on a machine with 15.4GB of RAM
12:09:31
12:09:31 The minimum required amount of free memory is around 16GB,
12:09:31 and even with that, some configurations may not work.
12:09:31
12:09:31 If you run into segfaults or other errors, try reducing your
12:09:31 -j value.

This error usually means the build process was killed by the OS in your laptop due to having no RAM left. You can confirm by running dmesg after the error and seeing in kernel logs that your process got killed.
