Subject: [Buildroot] [PATCH 9/9] package/sysdig: add sysdig-legacy
Date: Fri, 30 Oct 2026 16:24:34 +0100	[thread overview]
Message-ID: <20261030152434.3738285-9-angelo.compagnucci@gmail.com> (raw)
In-Reply-To: <20261030152434.3738285-1-angelo.compagnucci@gmail.com>

Add sysdig-legacy, providing sysdig 0.31.5 on 32-bit architectures. It
is the last version using falcosecurity-libs 0.10.5, provided by
falcosecurity-libs-legacy, and the 32-bit architectures are now enabled
in falcosecurity-libs.

sysdig-legacy builds the userspace libraries from the
falcosecurity-libs-legacy sources and links them statically, as it
doesn't install them.

To keep the build small, it uses the minimal build, which doesn't
support Kubernetes, Mesos, the container metadata and the eBPF probe, so
it doesn't need grpc, protobuf, c-ares, libcurl, openssl and elfutils.
The full build can be enabled in a following patch.

The libsinsp examples are not built, as they are not needed and fail
to build with musl.

Patches: backport the upstream switch to C++17, as needed by the
libabseil-cpp headers included by re2.
