Hi,

I trying to install nftables from source ask part of my Outreachy application tasks. I already installed libmnl and libnftnl successfully.

The problem comes after the 'make' command while trying to compile nftables. I'm running Ubuntu 16.04 and following the steps described here: https://wiki.nftables.org/wiki-nftables/index.php/Building_and_installing_nftables_from_sources

I removed the last commit of the nftables master branch: 8dee5e43ad4beb2b0a95e0bbf2b3972630c1b327 'netlink: Use nftnl_expr_fprintf() in netlink_dump_expr()', to avoid a compilation error because a dependency with a libnftnl's patch still pending to apply. But the following error is beyond my skills right now and maybe is just a detail that I'm missing and somebody can help me.

Thanks in advance
frank

Here is the relevant make output:
