<h3 class="section">2.6 Options for directory search</h3>
<a name="index-directory_002c-options"></a>
<a name="index-options_002c-directory-search"></a>
<a name="index-search-path"></a>
<a name="index-INCLUDE-directive"></a>
<a name="index-directive_002c-INCLUDE"></a>
<p>These options affect how GNU Fortran searches
for files specified by the <code>INCLUDE</code> directive and where it searches
for previously compiled modules.
</p>
<p>It also affects the search paths used by <code>cpp</code> when used to preprocess
Fortran source.
</p>
<dl compact="compact">
<dt><code>-I<var>dir</var></code></dt>
<dd><a name="index-Idir"></a>
<a name="index-directory_002c-search-paths-for-inclusion"></a>
<a name="index-inclusion_002c-directory-search-paths-for"></a>
<a name="index-search-paths_002c-for-included-files"></a>
<a name="index-paths_002c-search"></a>
<a name="index-module-search-path"></a>
<p>These affect interpretation of the <code>INCLUDE</code> directive
(as well as of the <code>#include</code> directive of the <code>cpp</code>
preprocessor).
</p>
<p>Also note that the general behavior of <samp>-I</samp> and
<code>INCLUDE</code> is pretty much the same as of <samp>-I</samp> with
<code>#include</code> in the <code>cpp</code> preprocessor, with regard to
looking for <samp>header.gcc</samp> files and other such things.
</p>
<p>This path is also used to search for <samp>.mod</samp> files when previously
compiled modules are required by a <code>USE</code> statement.
</p>
<p>See <a href="http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html#Directory-Options">Options for Directory Search</a> in <cite>Using the GNU Compiler Collection (GCC)</cite>, for information on the
<samp>-I</samp> option.
</p>
</dd>
<dt><code>-J<var>dir</var></code></dt>
<dd><a name="index-Jdir"></a>
<a name="index-Mdir"></a>
<a name="index-paths_002c-search-1"></a>
<a name="index-module-search-path-1"></a>
<p>This option specifies where to put <samp>.mod</samp> files for compiled modules.
It is also added to the list of directories to searched by an <code>USE</code>
statement.
</p>
<p>The default is the current directory.
</p>
</dd>
<dt><code>-fintrinsic-modules-path <var>dir</var></code></dt>
<dd><a name="index-fintrinsic_002dmodules_002dpath-dir"></a>
<a name="index-paths_002c-search-2"></a>
<a name="index-module-search-path-2"></a>
<p>This option specifies the location of pre-compiled intrinsic modules, if
they are not in the default location expected by the compiler.
