libisc-9.16.15-Debian.so: undefined symbol: uv_udp_connect

[Petr Menšík]

Can you check with ldd whether libuv is explicitly set on libisc library?

ldd /usr/lib/x86_64-linux-gnu/libisc-9.16.15-Debian.so

It works on Fedora just fine:

ldd /usr/lib64/libisc-9.16.21-RH.so | grep libuv
    libuv.so.1 => /lib64/libuv.so.1 (0x00007f4bf7716000)

readelf --dyn-syms /lib64/libuv.so.1 | grep uv_udp_connect
   462: 000000000000f490   417 FUNC    GLOBAL DEFAULT   13 uv_udp_connect

Dependencies on packaging system should ensure libuv cannot be
uninstalled without uninstalling dnsutils first. Either packagers on
Debian made mistake or some of your files are corrupted.

Can you try command:

LD_DEBUG=files host --help

It should list libuv.so.1 in the process, therefore this error cannot
happen.

Regards,
Petr
