<h2>1. Introduction</h2>
<p> This guide is intended to help those new to palm programming get started
developing using linux, PRC Tools, GNU tools, and the PalmOS&copy; SDK. It
assumes a fair knowledge of linux and <a href="http://www.gnu.org">GNU</a> tools
and a user level understanding of the PalmOS. There are development tools for
Windows, but whaateverrr. If you find this at all useful please drop me
a 5+ word email, for gloating statistics.
<p>
These are my notes from the night when I learned these tools. It
will take you from clueless to empowered (able to compile a HelloWorld program).
I couldn't find a working equivalent. So, I hope this information will be
helpful, but it is provided with no warranty or gaurantee. If you break anything
you get to keep both pieces.
<br>
<a href="#top">[top]</a>
<a name="req"></a>
<h2>2. Requirements</h2>
<p> You'll need to download the PRC tools, the palm emulator, the PalmOS &copy; SDK, and some <a href="http://www.gnu.org">GNU</a>
development tools ( see <a href="#dloads">downloads</a> ). I downloaded to ~/palm/archive (YMMV). </p>
<h4>PalmOS &copy; SDK</h4>
Get sdk,examples, and docs (hidden behind cgi that makes you read license agreement) <br>
<a href="http://www.PalmOS.com/dev/tech/tools/sdk35.cgi">http://www.PalmOS.com/dev/tech/tools/sdk35.cgi</a><br>
<li>sdk35-docs.tar.gz
<li>sdk35-examples.tar.gz
<li>sdk35.tar.gz
<h4>PalmOS &copy; Emulator</h4>
<p> Building the emulator for linux was a another step I didn't want to deal
with <b>yet</b>. Fear not. It's Weller with 2 L's. I will do it soon, and I'll
rewrite this doc to reflect that portion. For now I just got the windows prebuilt emulator and skins.
Pretty straight forward. You install a palm app that comes with the package to
your handheld. This allows you to download the PalmOS &copy; image from the palm's rom.
You have to pay money and sign an NDA (double whammy) to get other rom
images/versions. Anybody got an archive ;) Do the deed as in the readmes and
Blamh your palm on your desktop. Plus you can hotsync over the network with the
regular hotsync manager and the emulator. </p>

<li>emulator-win.zip
<li>emulator_skins_15.zip
<h4>PRC Tools</h4>
Get the prc tools (patches to <a href="http://www.gnu.org">GNU</a> tools and some palm tools )<br>
<a href="http://www.PalmOS.com/dev/tech/tools/gcc/">http://www.PalmOS.com/dev/tech/tools/gcc/</a><br>
<li>prc-tools-2.0.tar.gz
<h4>GNU Tools</h4>
Get gdb,gcc,binutils<br>
<a href="ftp://ftp.gnu.org/pub/gnu">ftp://ftp.gnu.org/pub/gnu</a><br>
<li>gdb-4.18.tar.gz
<li>gcc-2.95.2.tar.gz
<li>binutils-2.91.tar.gz
<br><br>
<a href="#top">[top]</a><a name="install"></a>
<h2>3. Setting up, building and installing the tools</h2>
Now your ready to unpack, configure, build, and install the tools. You need to do all
the commands listed in the box below: including LONG ASS COMPILE&reg;: Complete with Jim-isms and fixes.
Here are some things to keep in mind about the commands in the box below.<br><br>
<li> The SDK is not right for linux. You'll notice a move from the "Palm OS 3.5 Support" to sdkpalmos-3.5 and Incs to includes.
<li> Since you'll need your new versions of binutils during the build, put /usr/local/palm/bin in your PATH ahead of time
<li> I use the MYARCHIVEDIR and MYPALMDIR variables to store the location of important files
<li> The default install goes to /usr/local. I like to comparmentalize things in /usr/local/&lt;app&gt;. That's
/usr/local/palm in this case. Then I add /usr/local/palm/bin to my PATH.<br><br>
<table border=0 cellspacing=0 cellpadding=5>
<tr>
<td bgcolor="#d9d9d9">
<pre>
export MYPALMDIR=/root/palm
export MYARCHIVEDIR=$MYPALMDIR/archive
export PATH=/usr/local/palm/bin:$PATH

<p>
Assuming all goes as expected. You'll have the SDK stuff in /usr/local/palmdev
and then platform specific tools (m68k-palmos-gcc,m68k-palmos-c++,m68k-palmos-ranlib, etc.) in /usr/local/palm. Now
put /usr/local/palm/bin in your permanent path (edit .bashrc,.cshrc, profile etc.).
</p>
<a href="#top">[top]</a><a name="hello"></a>
<h2>4. A Hello World Program</h2>
<p>
Now you can compile a hello proggie.
<p>
I had to hack up all the demos from the HOWTOs after
reading the SDK header files. The header names, primitive types, and compiler
tool's names are incorrect for version 3.5 of the PalmOS &copy; SDK in the HOWTO
samples. Plus, it appears that the Examples that come with the SDK all have zero length
resource files (e.g. SampleCalculator.rsrc). I compiled the packages, but they
crashed on the emulator.
<p>
Save the below snippet in a text file called hello.c .
</p>
<a href="http://www.jimweller.net/palmdevqs-files/hello.c">hello.c</a><br>
<table border=0 cellspacing=0 cellpadding=5>
<tr>
<td bgcolor="#d9d9d9">
<pre>
#include &lt;PalmOS.h&gt;
// ---------------------------------------------------------------------
// PilotMain is called by the startup code and implements a simple event
// handling loop.
// ---------------------------------------------------------------------
UInt32 PilotMain( UInt16 cmd, void *cmdPBP, UInt16 launchFlags )
{
EventType event;
if (cmd == sysAppLaunchCmdNormalLaunch) {
// Display a string.
WinDrawChars( "Hello, world!", 13, 55, 60 );
// Main event loop:
do {
// Doze until an event arrives.
EvtGetEvent( &event, evtWaitForever );
// System gets first chance to handle the event.
SysHandleEvent( &event );
// Normally, we would do other event processing here.
// Return from PilotMain when an appStopEvent is received.
} while (event.eType != appStopEvent);
}
return;
}
</pre>
</td>
</tr>
</table>
<p>
You can compile it like this. Did you fix your PATH to have /usr/local/palm/bin ?
</p>
<table border=0 cellspacing=0 cellpadding=5>
<tr>
<td bgcolor="#d9d9d9">
<pre>
m68k-palmos-gcc hello.c -o hello
m68k-palmos-obj-res hello
build-prc hello.prc "Hello, World" WRLD *.hello.grc
</pre>
</td>
</tr>
</table>
<p>
Blamho! Now you'll have a hello.prc that you can put in the emulator (works!) or in your palm (WORKS!).<br><br>

<a href="#top">[top]</a><a name="hello"></a>
<h2>5. Screen Shots</h2>
<p>Here's some pics and screen shots of the emulator (running under windows) running hello.prc (compiled under linux).
You'll note the name of the app is what was specified on the build-prc command line. I also tested the hello.prc file
on my PalmIIIe. It Works!
