Remove libbpf as a submodule Instead clone the libbpf repo at a specific hash during setup. This is to fix an issue whereby submodules are not included in the tarball and therefore won't be updated/fetched during setup after unzipping the tarball. 2024-03-07 20:11:48 +00:00			`#!/bin/bash`

Fix issue when CDPATH contains libbpf directory When CDPATH is set the fetch_libbpf build script will cd into the preferred CDPATH directory. This change removes the CDPATH environment variable so any preferred CDPATH paths are ignored. The issue can be reproduced with the following steps: 1) mkdir -p /tmp/libbpf 2) CDPATH=/tmp/ meson setup build --prefix /tmp The build should fail at the fetch_libbpf step.
