How to resolve "ld terminated with signal 9 [Killed]" on WSL?


Here are the steps I completed before failure on WSL:

Note: using Python 3.11 and rustc 1.74.0-nightly

git clone [email protected]:<username>/polars.git
cd polars
rustup toolchain install nightly --component miri
cd py-polars
make test

The log is quite verbose, and here is the latest lines of log:

For more details on the OS, I'm using WSL (ubuntu 20.04) on Windows 11.


Solution

  • As suggested by @kmdreko, it was an out of memory issue

    I needed to dig into the default max RAM allowed on WSL, and I found it's by default 50% of total memory on Windows or 8GB.

    My PC only has 8GB RAM available, so on WSL I was not getting more than 4GB RAM by default.

    I fixed this issue by creating a .wslconfig file in my Windows Home folder (C:\Users\<UserName>) and writing the following to it:

    [wsl2]
    memory=7GB
    

    Then, the make test command completed successfully.
