Subject: [Buildroot] [PATCH 6/9] package/falcosecurity-libs: convert to a virtual package
Date: Fri, 30 Oct 2026 14:59:13 +0100	[thread overview]
Message-ID: <20261030135916.3599219-6-angelo.compagnucci@gmail.com> (raw)
In-Reply-To: <20261030135916.3599219-1-angelo.compagnucci@gmail.com>

Since version 0.11.0, the falcosecurity-libs userspace libraries only
support 64-bit architectures, as they get the system call numbers from
tables which only exist for them.

In order to provide a different version for 32-bit architectures,
convert falcosecurity-libs into a virtual package. For now, it is only
provided by falcosecurity-libs-latest, which is the former
falcosecurity-libs package, unchanged.

The license, the driver name, the kernel module make options and the
Linux kernel configuration fixups, which will be shared by the
providers, stay in the virtual package.
