<concept id="GUID-F5D49215-B34A-5FCC-A7E1-0AF3275694B3" xml:lang="en"><title>GCCXML

build target</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The GCCXML build target generates an XML description of the project and

the program. This XML is intended to be parsed by other development and program

analysis tools. The XML is generated using the GCC-XML (<xref href="http://www.gccxml.org" scope="external">http://www.gccxml.org</xref>) tool, which is distributed

on kits in the <filepath>epoc32\tools\</filepath> directory. </p>

<p>To execute a GCCXML build, use the <filepath>abld</filepath> command as

follows: </p>

<p><userinput>abld build gccxml [udeb/urel]</userinput> </p>

<p>GCCXML is available as a target for all projects that can be built for

an ARM target (this is assumed by the build tools unless the <filepath>bld.inf</filepath> file

specifies otherwise with a <codeph>prj_platforms</codeph> statement.) </p>

<p>The build of a Symbian platform component for the GCCXML platform results

in three actions: </p>

<ol id="GUID-631DFF50-B9DB-5FAD-A1F5-DBD74995772E">

<li id="GUID-E51ED016-411E-5754-8B7B-13C6459B4206"><p>The GCC-XML tool is

called on each source file used in the build of a component's binary. An XML

file is output as a result. </p> <p>The GCC-XML output format is not yet extensively

documented: see <xref href="http://www.gccxml.org/HTML/FAQ.html" scope="external">http://www.gccxml.org/HTML/FAQ.html</xref> for

the latest information. </p> </li>

<li id="GUID-7C664D07-2D30-5A96-A4CF-B3404C622206"><p>The tool chain also

generates an XML file describing some elements of the component's .mmp file. </p> <p>The

XML format is described below. </p> </li>

<li id="GUID-9259CF29-1B9D-5607-BDCC-104AD99F34C3"><p>The tool chain packages

the output from steps 1 and 2 into a zip file named <filepath>&lt;project-name&gt;.gxp</filepath>.

The file is stored in <filepath>epoc32\release\gccxml\[udeb|urel]\</filepath>. </p> </li>

</ol>

<section><title>Format of &lt;project&gt;.mmp.xml </title><p>A GCCXML build creates

an XML representation of the project's mmp file named <filepath>&lt;project&gt;.mmp.xml</filepath>.

Not all the mmp file statements are represented in the XML. </p><p>The following

XML elements and attributes are used: </p><table id="GUID-93991E16-AE60-550C-80BA-316285A463C7">
