and file types used in the build process</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>This page briefly lists the main Symbian-specific tools and file types
used in building components. In addition to these tools, the build process
will use compilers and linkers supplied by various third party companies. </p>
<p>Tools supplied by Symbian are in <filepath>epoc32\tools\</filepath> directory. </p>

<entry><p> <b>Description</b>  </p> </entry>
</row>
<row>
<entry><p> <filepath>bldmake</filepath>  </p> </entry>
<entry><p>This tool processes a component description file (<filepath>bld.inf</filepath>),
which describes various aspects of the component, and generates make files
and a batch file called <filepath>abld.bat</filepath>. This batch file is
then used to drive the rest of the component build. </p> </entry>
</row>
<row>
<entry><p> <filepath>abld</filepath>  </p> </entry>
<entry><p>Calls the <filepath>.make</filepath> files generated by the <filepath>bldmake</filepath> tool
to build a component. The make files typically call the <filepath>makmake</filepath> tool
to create makefiles that specify the required build steps to build the component
for a particular target. </p> </entry>
</row>
<row>
<entry><p> <filepath>makmake</filepath>  </p> </entry>
<entry><p>Takes a <filepath>.mmp</filepath> project file which lists the elements
of the project, and produces a makefile for the platform specified. The GCC <filepath>make</filepath> utility
is then called to execute the make file. </p> </entry>
</row>
<row>
<entry><p> <filepath>elf2e32</filepath>  </p> </entry>
<entry><p>Converts the ELF representation of an executable into an E32Image
format file, the format required to run on Symbian platform. Used only for
ARMV5 (ABIv2) target. </p> </entry>
</row>
<row>
<entry><p> <filepath>elftran</filepath>  </p> </entry>
<entry><p>Transforms the ELF representation of an executable into an E32Image
format file, the format required to run on Symbian platform. Used only for
ARMV5 (ABIv1) target. </p> </entry>
</row>
<row>
<entry><p> <filepath>elf2Inf</filepath>  </p> </entry>
<entry><p>Gets a list of the symbol names of the exported definitions from
an ELF file. Its output <filepath>.inf</filepath> file is input to <filepath>makedef</filepath>.
Used only for ARMV5 (ABIv1) target. </p> </entry>
</row>

<row>
<entry><p> <filepath>makedef</filepath>  </p> </entry>
<entry><p>Maintains or creates DEF files, which record an executable's exported
symbols by ordinal. </p> </entry>
</row>
<row>
<entry><p> <filepath>def2dll</filepath>  </p> </entry>
<entry><p>Creates binary objects used to implement the Symbian platform DLL
model. These are a representation (ELF) of the export table (<filepath>.exp</filepath> file),
and its import library (<filepath>.lib</filepath>). Used only for ARMV5 (ABIv1)
target. </p> </entry>
</row>
<row>
<entry><p> <filepath>epocrc</filepath>  </p> </entry>
<entry><p>Combines the actions of passing a resource file through the C++
preprocessor, and then compiling it with the <filepath>rcomp</filepath> tool. </p> </entry>
</row>
<row>
<entry><p> <filepath>rcomp</filepath>  </p> </entry>
<entry><p>Resource compiler. Compiles source <filepath>rss</filepath> resource
files into compiled resource data files, and a <filepath>rsg</filepath> resource
header file. </p> </entry>
</row>
<row>
<entry><p> <filepath>bmconv</filepath>  </p> </entry>
<entry><p>Bitmap converter. Takes one or more Microsoft Windows bitmaps <filepath>.bmp</filepath> and
generates a single multi-bitmap file <filepath>.mbm</filepath>, optimised
for efficient runtime loading by the GDI. Also a header file <filepath>.h</filepath> with
symbolic definitions for each bitmap in the file. </p> </entry>
