  • From here you can download all tools necessary to develop applications under Linux (or Unix).
  • Sourceforge.net is the home of the PRC tools.
  • the pilot-link portal has all the stuff you need to communicate with your Palm.
  • the lastest version of PilRC (the resource compiler) can be found at sourceforge.net.

Debugging Your Application
POSE   The current emulator for the Palm device is called POSE. It contains many improvements (it can e.g. run Pilot ROM's up to version PalmOS-4.x) and also debugging applications has become simpler with POSE than with it's predecessor XCopilot.

As usual, programs have to be compiled with gcc "-g" option, if you want to debug them using gdb. This adds debugging information to the program and lets the program ask for a feature with creator ID "gdbS" ("gdbS" belongs to gdbpanel; this program is obsoleted by POSE). If the feature is set, the program asks to enter debug mode.

POSE automatically sets this feature and checks, if a debugger is connected to POSE. If so, a break at PilotMain() is forced and the control is given to the debugger connected.

What remains to discuss is how to connect gdb to POSE; the patched version of gdb knows a command "target pilot <host>:<port>". By default POSE creates two sockets at port 2000 and a user defined port (in ~/.poserrc exists a option DebuggerSocketPort=6414, which seems to define this port). It remains to start gdb and load the program you want to debug ("file <prg>"; choose the program without suffix ".prc") and enter the command "target pilot localhost:2000". If you then start the program in POSE that you want to debug, you should find gdb at its command prompt.

I recommend you to create a file ".gdbinit" in the directory, where you start gdb. This file should contain a line

target pilot localhost:2000
This line will then be evaluated, if you start gdb; so you don't have to enter this command every time you want to debug a program.
