Description Petross404(Petros S) 2017-12-26 20:01:01 UTC

Compiling =dev-perl/Tk-804.33.0 failes with:

/usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: cannot find -lnsl

Emerging net-libs/libnsl allowed Tk to build successfully. So, is it an undeclared dependency?

  my @try   = qw(-lsocket -lnsl -lm);
  push(@try,'-lc') if $^O =~ /svr4/i;


*sigh*

I'm currently trying to reproduce this and I don't seem to able to replicate the problem, even without libnsl installed.

Despite the mentions of -lnsl in the source code, those are "soft-auto-detect" paths, and you shouldn't need libnsl installed to make dev-perl/Tk compile.

Its possible you've run afoul of Perl auto-including nsl in its configure (see bug #638518 for details ), so please make sure that:

    /usr/bin/perl -V | grep nsl

Emits no output before re-attempting.

Let's hope this is fixed with newer dev-lang/perl.
