Compilation with gpgsql module: cannot find -lnsl

[soullivaneuh]

I'm trying compiling powerdns with gpgsql module for PostreSQL on Alpine linux (Docker) and I get this following error:

CXXLD  pdns_server
/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find -lnsl
collect2: error: ld returned 1 exit status
Makefile:1379: recipe for target 'pdnssec' failed

/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find -lnsl

What is the lib nsl?

Please attach config.log and output of a build with make V=1.
libnsl is a solaris thing, usually.

Please attach config.log

Where should I find this file?

Given this is a build against musl, I assume this is #1967. You'll need the referenced patches or 4.0.

[soullivaneuh]

You'll need the referenced patches

Do this patch of the PR #1990 will work on 3.4?

Can we just compile this needed library? Where can I find it?

Do this patch of the PR #1990 will work on 3.4?

That's for you to find out. I'd think it would.

[soullivaneuh]

The patch is actually not working with latest 3.4 version.

You will be able to see results here: https://travis-ci.org/dockervan/powerdns/jobs/103065381

@James-TR said this patch works also on 3.4 (#1967 (comment)).

Any chance to have it on a new patch version?
