Irix 6.3 and later are okay.</p> <pre><code>Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX pthreads patches information.</code></pre> <h2 id="Irix-5.3"><a class="permalink" href="#Irix-5.3">#</a><a id="Irix"></a>Irix 5.3</h2> <p>While running Configure and when building, you are likely to get quite a few of these warnings:</p> <pre><code class="plaintext">ld: The shared object /usr/lib/libm.so did not resolve any symbols. You may want to remove it from your link line.</code></pre> <p>Ignore them: in IRIX 5.3 there is no way to quieten ld about this.</p> <p>During compilation you will see this warning from toke.c:</p> <pre><code class="plaintext">uopt: Warning: Perl_yylex: this procedure not optimized because it exceeds size threshold; to optimize this procedure, use -Olimit option with value >= 4252.</code></pre> <p>Ignore the warning.</p> <p>In IRIX 5.3 and with Perl 5.8.1 (Perl 5.8.0 didn't compile in IRIX 5.3) the following failures are known.</p> <pre><code class="plaintext">Failed Test Stat Wstat Total Fail Failed List of Failed -------------------------------------------------------------------------- ../ext/List/Util/t/shuffle.t 0 139 ?? ?? % ?? ../lib/Math/Trig.t 255 65280 29 12 41.38% 24-29 ../lib/sort.t 0 138 119 72 60.50% 48-119 56 tests and 474 subtests skipped.

If you can get gcc for 5.3, you could try that, too, since gcc in IRIX 6 is a known workaround for at least the shuffle.t and sort.t failures.</p> <h1 id="AUTHOR"><a class="permalink" href="#AUTHOR">#</a>AUTHOR</h1> <p>Jarkko Hietaniemi <jhi@iki.fi></p> <p>Please report any errors, updates, or suggestions to <i>perlbug@perl.org</i>.</p> </div> <div id="footer"> <p>Perldoc Browser is maintained by Dan Book (<a href="https://metacpan.org/author/DBOOK">DBOOK</a>).
