reproducible deps

10 Feb 2019

Dependencies:

smf comes with the ability to fetch and build transitive dependencies on it’s own at known revisions for reproducible builds.

To enable reproducible builds, simply invoke cmake like so:

mkdir build && cmake -GNinja -DSMF_MANAGE_DEPS=ON -DCMAKE_BUILD_TYPE=Release ..

By default automatic dep management is off (i.e.: -DSMF_MANAGE_DEPS=OFF) so you can use smf as part of a larger cmake project

Next steps / help wanted

I’d love to make most of the dependencies statically compiled into the final binary.

The only issue I ran into was w/ the TLS libraries.

protobuf, cares, lz4, z, lzma, xml2 are easy to change. They already produce the .a files for linking.

The only remaining problematic libs are hwloc, numa, gnutls, nettle, hogweed, gmp
