    <p>First of all, I'm not familiar with Perl and it's practices.</p> <p>I'm trying to develop an <a href="https://en.wikipedia.org/wiki/Ebuild" rel="nofollow">ebuild</a> that installs a Perl application. However I don't know where to put the library files of the application.</p> <p>The application's directory structure is</p> <pre><code>binary share/app/*.pl share/app/icons/*.png </code></pre> <p><code>binary</code> being the Perl executable.</p> <p>In the binary I see lines like <code>require 'someLibrary.pl';</code> these refer to the Perl libraries in the <code>share/app/</code> directory. I also notice a <code>use lib "$BIN/share/app";</code> line, which tells the binary where to locate the additional libraries I guess.</p> <p>Now I face the problem how to install the application.</p> <p><strong>Solution #1:</strong> Install the binary in <code>/usr/bin/</code> and the libraries in <code>/usr/lib/perl5/</code>.</p> <p><strong>Problem:</strong> Where to put the icons? The icons are referred in the binary and libraries using <code>$Bin/share/app/icons/*.png</code>. This won't work I guess.</p> <p><strong>Solution #2:</strong> Install everything in <code>/usr/share/app/</code>.</p> <p><strong>Problem:</strong> Where to put the binary? Create a symlink in <code>/usr/bin/</code> to the binary?</p> <p><strong>Solution #3:</strong> Patch the Perl files so they look for icons in <code>/usr/share/app/icons</code>, place the binary in <code>/usr/bin/</code> and the libraries in <code>/usr/lib/perl5/</code>.</p> <p><strong>Problem:</strong> I have to create a patch for the files. This doesn't seem like a good/normal way.</p> <p>Of course other solutions are more than welcome.</p> <p><strong>Update:</strong> I've tried solution #2 and as I suspected, when I execute <code>/usr/bin/binary</code> the library path gets turned into <code>/usr/bin/share/app</code>. This of course results in the libraries not being found.</p>

    1. COI don't think there are really standard Perl practices to guide you in a case like this. Do what makes most sense for Gentoo and for the requirements of the existing code. #2 with a symlink sounds best to me, if there is a good reason not to edit the Perl files.

    2. COHow is `$BIN` defined? Are the additional libraries specific to this application or is it copies of CPAN libraries and if the former are they contained in a proper namespace?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
