Re: [Pdl-devel] PDL and its pre-req PerlIO::Layers fail to build in macOS 10.13.3

[Derek L. <de...@bo...>]

Hi Will,

This doesn't really seem to be a PDL issue.  And you don't say whether you've been able to install on prior versions of macOS.  But my PerlIO::Layers installed from MacPorts just fine on macOS 10.12.x (Sierra), and it doesn't look like MacPorts does anything special to make it work.  And PerlIO::Layers hasn't been updated in 4 years, so it's probably not a recent issue.

All of that suggests that it's something on your end.  The PerlIO::Layers test that fails relies on open3 and waitpid, which means child processes etc are at work here.  I notice you're trying to install with sudo.  Are you installing into a user or a system directory?  If you do a 'man perlrun' you can get descriptions of the PERL5LIB and PERL5OPT environment variables.  The fact that they are not set here is interesting, considering you say you set PERL5LIB in your env.  Is PERL5LIB exported?  Have you sourced your ~/.profile (or whatever) since setting that, either explicitly or by opening a new terminal window?

To be completely pedantic, I would expect to see something like:

export PERL5LIB="/Users/carly/perl5"

in your ~/.profile file. (that assumes some things about what's in that directory, but absent an explanation I am just making a guess.)

PERL5LIB is set in my env (bash) but I am not setting PERL5OPT, whatever that means in this build. If PERL5LIB must be resolved, the build script is not pulling it from my env, and if PERL5OPT must be set, I need to know what to set it to.
