<p>The Automatic or Manual build procedures create the Flickernoise VJ application for the Milkymist One. The final Flickernoise executable is an ELF binary. From that, you can either:
</p>
<ul><li> try the ELF binary in the QEMU emulator with <code>qemu-system-lm32 -M milkymist -kernel flickernoise</code>
</li><li> generate a raw binary file with <code>make flickernoise.ralf</code>, suitable for TFTP netbooting (recommended), booting from the memory card or downloading over the serial line with flterm. Using flterm is not recommended as this method is slow because of the large size of the binary.
</li><li> generate a FBI image with <code>make flickernoise.fbi</code> that you can use with the auto-upgrade feature of Flickernoise (0.2+).
</li></ul>

<p>First you need to follow the <a href="index.php%3Ftitle=RTEMS_build_instructions.html" title="RTEMS build instructions">RTEMS build instructions</a>. We will assume you have installed both RTEMS and the toolchain in <code>/opt/rtems</code> (or /opt/rtems-VERSION). Not installing RTEMS and the toolchain in the same directory tends to cause problems w.r.t. finding include files.
</p><p>We recommend using the GCC 4.5.1 based toolchain, which works reasonably well. You will however need to patch GCC a bit so the base C libraries can use all the features of our LM32 implementation:

</pre>
<p>Once you have the toolchain and RTEMS installed:
</p>
<ul><li> make sure the toolchain binary directory (e.g. <code>/opt/rtems/bin</code>) is in your <code>PATH</code>, so that the <code>lm32-rtems4.11-*</code> family of commands is found.
</li></ul>
<pre>export PATH=/opt/rtems-4.11/bin:$PATH
</pre>
<ul><li> set the <code>RTEMS_MAKEFILE_PATH</code> environment variable, e.g. to <code>/opt/rtems-4.11/lm32-rtems4.11/milkymist</code>
</li></ul>
<pre>export RTEMS_MAKEFILE_PATH=/opt/rtems-4.11/lm32-rtems4.11/milkymist

<p>Tested with curl 7.22.0. Configure with the usual Autocrap command line (as above). Special parameters are: <code>--host=lm32-rtems4.11 --disable-shared --without-librtmp --disable-ftp --disable-ldap --disable-ldaps --disable-rtsp --disable-dict --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smtp --disable-gopher --disable-manual --prefix=$RTEMS_MAKEFILE_PATH</code>
</p><p>Then you need to hack the generated files:
</p>
<ul><li> at the end of lib/setup.h add <code>#define HAVE_SOCKET 1</code>
</li></ul>

<p>Works with expat 2.0.1. Edit <code>conftools/config.sub</code> and replace <code>ppc</code> with <code>lm32</code>, then proceed like with Freetype.

<p>You will need gcc-avr.
</p><p>Make sure the <code>RTEMS_MAKEFILE_PATH</code> environment variable is set (see above).

</p><p>You will need <a href="http://www.hwaci.com/sw/lemon/" class="external text" title="http://www.hwaci.com/sw/lemon/" rel="nofollow">Lemon</a> and <a href="http://re2c.org/" class="external text" title="http://re2c.org/" rel="nofollow">RE2C</a> to compile libFPVM.
</p><p>Make sure the <code>RTEMS_MAKEFILE_PATH</code> environment variable is set (see above).
</p><p>dont forget PATH too, ie PATH=/opt/rtems-4.11/bin:$PATH

</p><p>After you have cloned the git repository, compilation is very simple:
</p>
<pre>make -f Makefile.rtems
make -f Makefile.rtems install
</pre>
<p>(Again, this command requires the RTEMS_MAKEFILE_PATH environment variable)

<a name="Flickernoise" id="Flickernoise"></a><h2><span class="editsection">[<a href="http://milkymist.org/wiki/index.php?title=Flickernoise_build_instructions&amp;action=edit&amp;section=14" title="Edit section: Flickernoise">edit</a>]</span> <span class="mw-headline"> <a href="http://www.milkymist.org/flickernoise.html" class="external text" title="http://www.milkymist.org/flickernoise.html" rel="nofollow">Flickernoise</a> </span></h2>
<p>Compile it with:
</p>
<pre> cd src
make
</pre>
<p>Do not forget to set the <code>RTEMS_MAKEFILE_PATH</code> environment variable to the right directory where your RTEMS is installed.
</p><p>This produces an ELF binary. From that, you can either:
</p>
<ul><li> try the ELF binary in the QEMU emulator with <code>qemu-system-lm32 -M milkymist -kernel flickernoise</code>
</li><li> generate a raw binary file with <code>make flickernoise.ralf</code>, suitable for TFTP netbooting (recommended), booting from the memory card or downloading over the serial line with flterm. Using flterm is not recommended as this method is slow because of the large size of the binary.
</li><li> generate a FBI image with <code>make flickernoise.fbi</code> that you can use with the auto-upgrade feature of Flickernoise (0.2+).
</li><li> generate a MCS flash image with <code>make flickernoise.mcs</code> that you can download into the board's flash memory so that Flickernoise automatically starts at every boot.
</li></ul>

</p><p>RTEMS lacks the required include file bits/wordsize.h so we create one:
</p>
<pre>mkdir /opt/rtems-4.11/lm32-rtems4.11/include/bits
cat &lt;&lt; EOF &gt; /opt/rtems-4.11/lm32-rtems4.11/include/bits/wordsize.h

<p>Edit the beginning of the Makefile to set:

<p>Also, they seem to have forgotten gd_security.c to the list of objects, so add it to LIBOBJS.
</p><p>Compile with:
</p>
<pre>make libgd.a

<p>Then copy libgd.a to /opt/rtems-4.11/lm32-rtems4.11/milkymist/lib and gd.h, gdcache.h, gd_io.h, gdfontg.h, gdfontl.h, gdfontmb.h, gdfonts.h and gdfontt.h to /opt/rtems-4.11/lm32-rtems4.11/milkymist/lib/include.

<p>Uncompress the archive, and edit the Makefile:

<p>RTEMS lacks memory.h so we create a fake one:
</p>
<pre>echo "#include &lt;string.h&gt;" &gt; libopenjpeg/memory.h
</pre>
<p>Type make to compile. Then ranlib and copy the library and its include file to the RTEMS directory:

<p>You will first need to re-generate config.sub using a recent version of automake. Indeed, the steaming pile of shit that constitutes GNU/Autocrap has a hardcoded list of CPUs it would support, and lm32 isn't included with many software packages.
</p>
<pre>rm config.sub
automake --add-missing
</pre>
<p>Ignore any warning about version mismatches that automake may puke out - trying to fix it actually makes the problem worse.
</p><p>Run the configure script, compile and install:
</p>
<pre>CFLAGS="-O9 -Wall -mbarrel-shift-enabled \
-mmultiply-enabled -mdivide-enabled -msign-extend-enabled \
-I $RTEMS_MAKEFILE_PATH/lib/include \

./configure --host=lm32-rtems4.11 --disable-shared --prefix=$RTEMS_MAKEFILE_PATH
make
make install
</pre>
<p>Again, move the include file:
</p>
<pre>mv /opt/rtems-4.11/lm32-rtems4.11/milkymist/include/* /opt/rtems-4.11/lm32-rtems4.11/milkymist/lib/include

gcc -o build/release/fontdump ./mupdf/fontdump.c -lfreetype -ljpeg -lz -lm -Ifitz

</li><li> set <code>CC&nbsp;:= lm32-rtems4.11-gcc</code>
</li><li> set <code>CFLAGS&nbsp;:= -Ifitz -Imupdf -Wall -O9 -Wall -mbarrel-shift-enabled -mmultiply-enabled -mdivide-enabled -msign-extend-enabled -I $(RTEMS_MAKEFILE_PATH)/lib/include -I $(RTEMS_MAKEFILE_PATH)/lib/include/freetype2 -B $(RTEMS_MAKEFILE_PATH)/lib -specs bsp_specs -qrtems</code>
</li></ol>
<p>Compile the MuPDF library with:
</p>
<pre>make build=release build/release/libmupdf.a
</pre>
<p>Finally, copy the includes and binaries to the RTEMS folder:
</p>
<pre>cp fitz/fitz.h /opt/rtems-4.11/lm32-rtems4.11/milkymist/lib/include
