<h1><span class="section-number">12.3. </span>Compiler Pickyness by Default<a class="headerlink" href="#compiler-pickyness-by-default" title="Permalink to this heading"></a></h1>
<p>If you are building PMIx from a Git clone (i.e., there is a
<code class="docutils literal notranslate"><span class="pre">.git</span></code> directory in your build tree), the default build includes
extra compiler pickyness, which will result in more compiler warnings
than in non-developer builds and will mandate that warnings be
treated as errors. Getting these extra compiler warnings
is helpful to PMIx developers in making the code base as clean as
possible.</p>
<p>Developers can disable this picky-by-default behavior by using the
<code class="docutils literal notranslate"><span class="pre">--disable-picky</span></code> configure option. Also note that extra-picky
compiles do <em>not</em> happen automatically when you do a VPATH build
(e.g., if <code class="docutils literal notranslate"><span class="pre">.git</span></code> is in your source tree, but not in your build
tree).</p>
<p>Prior versions of PMIx would automatically activate a lot of
(performance-reducing) debugging code by default if <code class="docutils literal notranslate"><span class="pre">.git</span></code> was found
in your build tree. This is no longer true. You can manually enable
these (performance-reducing) debugging features in the PMIx code
base with the <code class="docutils literal notranslate"><span class="pre">--enable-debug</span></code> configure option.</p>
