Add option to not encode resource data into the C source file in order to embed the data using `ld -b binary`. This improves compilation times, but can only be done on Linux or other platforms with a supporting linker. (Rebased by Philip Withnall, fixing minor rebase conflicts.) Fixes #1489

<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.

The XML resource files normally have the filename extension <filename>.gresource.xml</filename>.

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>.

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.

<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.

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

combined with other <option>--generate</option> options to generate dependencies

as a side-effect of generating sources.
