Source: mstflint Version: 4.13.3+2-1 mstflint build-deps on libjson-c-dev, but doesn't appear to use it. It builds fine w/o it installed, and none of the produced binaries dynamically link to libjson-c:
$ dpkg-deb -x /var/cache/apt/archives/mstflint_4.13.3+2-1_amd64.deb x/ $ find x -type f | xargs ldd | grep json $ We don't currently build any of the subcommands that #include json headers (mlxarchive, mlxfwupdate, mlxlink, from my grep) as they are not ./configure --enabled. And even if we did, they apparently wouldn't build w/ the system library anyway. For example: https://github.com/Mellanox/mstflint/issues/305 -dann
