<p>This is where you want to install your cross compilation toolchain.
It can be either installed system-wide (in <tt>/usr/local/arm/2.95.3</tt> for example). Installation steps (i.e. <tt>make install</tt>) will have
to be done as <tt>root</tt>.
Or it can be installed in user-land, for the user's own use (<tt>/home/foobar/arm/2.95.3</tt> for example).
In this paper, the chosen prefix is <tt>/usr/local/arm/2.95.3</tt>,
you will have to adapt the commands to what you choose..

I would advise you to completely log out and then log in again, so that
the change would be taken into account. You can now check that when you
type <tt>arm-linux-gcc</tt>, it launches the cross-compiler.
</p>
<p>
Next are some packages that you may compile by yourself, but I found
it was easier to use the precompiled packages. You can take them
at <htmlurl url="http://ipkgfind.handhelds.org/" name="ipkgfind">.
You may find packages with other version numbers which should not be
a problem.
<descrip>
<tag><tt>libgcc1_3.1.1-1_arm.ipk</tt></tag>
This provides libgcc.so.1 which is needed to compile some libraries.
<tag><tt>xlibs_4.1-5_arm.ipk</tt>, <tt>xlibs-dev_4.1.0-16_arm.ipk</tt></tag>
Those are the libraries ans the development files for X windows.
<tag><tt>zlib1g_1.1.4-3_arm.ipk</tt>, <tt>zlib1g-dev_1.1.3-fam1_arm.ipk</tt></tag>
These libraries are needed by some libraries to compile.

First get Tremor and ogg sources from xiph.org (through CVS for example).
Then for each them, do :
% ./configure --enable-release --prefix=/usr/local/arm/2.95.3/arm-linux
% export PATH=/usr/local/arm/2.95.3/arm-linux/bin:$PATH
% make
% su
# make install
I know it is not clean, but --host or --target switches does not work.
The PATH I include, contains all the gcc utils for cross compilation
without the arm-linux- prefix.
If you want to link them statically : edit the libvorbisidec.a and remove
from the archive bitwise.o and framing.o (conflict with libogg.a)
For flac, get the source tarball (from the videolan website for example)
% ./configure --enable-release --host=arm-linux --target=arm-linux
--prefix=/usr/local/arm/2.95.3/arm-linux
% make
-> will fail (xmms plugin), but not a problem, continue installation by hand
% su
# cp -Rf include/FLAC /usr/local/arm/2.95.3/arm-linux/include
# cd src/libFLAC
# make install
When compiling vlc, add to the ./configure :
--enable-ogg
--enable-tremor
--enable-flac

have a look rules.* in the ipkg directory. <p>
First of all, run the <tt>./bootstrap</tt> script.
Then run one of the <tt>ipkg/rules.*</tt>, according to what you want to compile.
Finally you just have to type make and you'll get a stand alone vlc.
</p>
<p>
Run <tt>arm-linux-strip</tt> to remove symbols and so the size of the file,
and now you can test it easily on your PDA.

Enjoy !
