<refsect1><title>Description</title>
<para><command>glib-compile-resources</command> reads the resource description from
<replaceable>FILE</replaceable> and the files that it references
and creates a binary resource bundle that is suitable for use with the
<link linkend="GResource"><type>GResource</type></link> API.
The resulting bundle is then written out as-is, or as C source for linking into
an application.
</para>
<para>
The XML resource files normally have the filename extension <filename>.gresource.xml</filename>.
For a detailed description of the XML file format, see the
<link linkend="GResource"><type>GResource</type></link> documentation.

<varlistentry>
<term><option>--target=<replaceable>TARGET</replaceable></option></term>
<listitem><para>
Store the compiled resources in the file <replaceable>TARGET</replaceable>.
If not specified a filename based on the <replaceable>FILE</replaceable>
basename is used.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--sourcedir=<replaceable>DIRECTORY</replaceable></option></term>
<listitem><para>
The files referenced in <replaceable>FILE</replaceable> are loaded from
this directory. If not specified, the current directory is used.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--generate</option></term>
<listitem><para>
Write the output file in the format selected for by its filename extension:
<variablelist>

<term><literal>.c</literal></term>
<listitem><para>C source</para></listitem>

</variablelist>
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--generate-source</option></term>
<listitem><para>
Instead of a writing the resource bundle in binary form create a C source file
that contains the resource bundle. This can then be compiled into an
application for easy access.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--generate-header</option></term>
<listitem><para>
Generate a header file for use with C code generated by
<option>--generate-source</option>.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--generate-dependencies</option></term>
<listitem><para>
Prints the list of files that the resource bundle references to standard output.
This can be used to track dependencies in the build system. For example, the
following make rule would mark <replaceable>test.gresource</replaceable> as
depending on all the files that <replaceable>test.gresource.xml</replaceable>
includes, so that is is automatically rebuilt if any of them change:
<programlisting>
test.gresource: test.gresource.xml $(shell $(GLIB_COMPILE_RESOURCES) --generate-dependencies test.gresource.xml)
</programlisting>
Note that this may or may not be portable to non-GNU <command>make</command>.
</para>
<para>
Also see <option>--dependency-file</option>.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><option>--c-name</option></term>
<listitem><para>
Specify the prefix used for the C identifiers in the code generated by
<option>--generate-source</option> and <option>--generate-header</option>.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--manual-register</option></term>
<listitem><para>
By default code generated by <option>--generate-source</option> uses automatic
initialization of the resource. This works on most systems by using the
compiler support for constructors. However, some (uncommon) compilers may not
support this, you can then specify <option>--manual-register</option>,
which will generate custom register and unregister functions that your code
can manually call at initialization and uninitialization time.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--internal</option></term>
<listitem><para>
By default code generated by <option>--generate-source</option> declares all
initialization functions as <type>extern</type>.  So they are exported
unless this is prevented by a link script or other means.  Since libraries
usually want to use the functions only internally it can be more useful to
declare them as
<link linkend="G-GNUC-INTERNAL:CAPS"><literal>G_GNUC_INTERNAL</literal></link>
which is what <option>--internal</option> does.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--dependency-file=<replaceable>FILE</replaceable></option></term>
<listitem><para>
Write dependencies in the same style as gcc -M -MF to the given file.
If <option>FILE</option> is -, the dependencies are written to the standard
output. Unlike <option>--generate-dependencies</option>, this option can be
combined with other <option>--generate</option> options to generate dependencies
as a side-effect of generating sources.
</para></listitem>
</varlistentry>

<varlistentry>
<term><option>--generate-phony-targets</option></term>
<listitem><para>
When creating a dependency file with <option>--dependency-file</option>
include phony targets in the same style as gcc -MP. This would typically
be used with <literal>make</literal>.
</para></listitem>
</varlistentry>

</variablelist>

<refsect1><title>Environment</title>
<variablelist>

<varlistentry>
<term><envar>XMLLINT</envar></term>
<listitem><para>
The full path to the xmllint executable. This is used to preprocess resources
with the <literal>xml-stripblanks</literal> preprocessing option. If this
environment variable is not set, xmllint is searched in the
<envar>PATH</envar>.
</para></listitem>
</varlistentry>

<varlistentry>
<term><envar>GDK_PIXBUF_PIXDATA</envar></term>
<listitem><para>
The full path to the gdk-pixbuf-pixdata executable. This is used to preprocess
resources with the <literal>to-pixdata</literal> preprocessing option. If this
environment variable is not set, gdk-pixbuf-pixdata is searched in the
<envar>PATH</envar>.
