Edit: please take note this Mini-How to is obsolete now. Please go to Microchip's PICkit 2 website to download pk2cmd codes. It now supports Linux and Mac OS X along with Windows.
PICkit 2 (http://www.microchip.com/pickit2) is a nice little USB programmer from Microchip. It now supports many Flash MCUs from Microchip. As of now, most of the PIC12F/16F/18F 8-bit PIC MCUs and PIC24/dsPIC30/dsPIC33 16bit MCUs are supported (http://ww1.microchip.com/downloads/en/DeviceDoc/PICkit%202%20Readme%20v2-30.txt).
Microchip has kindly published the source codes for PICkit 2 firmware and the standardalone PC application (http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1960).
PICkit 2 works under Linux thanks to the efforts from several developers. The easiest to start with is pk2 from Jeff Post (http://home.pacbell.net/theposts/picmicro/). pk2-2.04 only supports version 1.x (up to V1.21) firmware. The upcoming pk2-3.x will support version 2.x firmware.
The following is the simple procedure to get pk2-2.04 built under Linux.
1) Make sure you have the necessary compiler (gcc/make) and libusb development package. Normally they are already included in the distribution.
2) Download pk2-2.04. Apply the follow patch for the file pk2usb.c.
//#if HAVE_LIBUSB_INTERRUPT_MODE
// latest libusb: interrupt mode, works with all kernels
# define PICKIT_USB(direction) usb_interrupt_##direction //only keep this line
//#else
// older libusb: bulk mode, will only work with older kernels
//# define PICKIT_USB(direction) usb_bulk_##direction
//#endif
3) Modify the default Makefile. Normally you should be using kernel version Linux 2.6.x and you should use the following option.
# ----- Use the following for Linux kernel 2.6.x: -----
CFLAGS=$(OPTS) -I$(LIBUSB)/include -DLINUX -DUSE_DETACH -DCLAIM_USB
4) Built pk2 with the command "make"
5) Test out pk2. Normally you need to run as root if you have not setup the proper hotplug/udev rules.
6) If it is okay, set up the hotplug/udev rules. This will depend on your distribution. The following is a quick start for you.

You can read the bundled usbhotplug.txt by Linus Walleij for more information about udev/hotplug.
7) If you encounter problems with pk2, try to ask question in pickit-devel mailing list (http://groups.google.com/group/pickit-devel). Take note that you should ask general questions about PICkit 2 in Microchip Forum (http://forum.microchip.com/tt.aspx?forumid=15). There are some good information about PICkit 2 in the Microchip Forum. In paticular, if you encounter USB emuneration problem under Linux, try the hardware changes detailed in the post (http://forum.microchip.com/tm.aspx?m=245280). Only Step 2 is necessary.
8) How to help out?
From Jeff Post: http://home.pacbell.net/theposts/picmicro/helping.html
Note on 10-April-2009: it is now better to use pk2cmd at Microchip PICkit 2 websites.

Xiaofan, I was real excited to see this post. But, alas, I think my issues are more fundamental.
Is there a particular location to put the pk2 source code? The reason is that I have tried both FC6 and FC7 and keeping running into issues of not finding certain .h files in the search path. Probably incorrectly, I add another -I option which fixes one "no such .h file" only to create another. So, I add another -I for that one, and so on. This surely is incorrect. It would seem that most folks just type "make" and things progress.
For example, the first one I encounter is not finding usb.h. I find it at /usr/src/kernels/2.6.20-1.2962.fc6-i686/include/linux so add a -I for this path. Next compile attempt then it seems that it can't find compiler.h which is in the directoty above where I found usb.h. So, I add a -I option for that. Clearly, this is nuts. What am I missing that is so fundamental here? Why would Fedora be so different from Ubuntu when it comes to compiling the source?
So, this is where I can use some help. Seems that "make" is a pretty big leap! It's probably obvious stuff for you experts but not for all of us ... some hints would be greatly appreciated.
This bas been solved in pickit-devel Google group. You need to havelibusb (and libusb-devel) installed.
pk2cmd Linux port is now the preferred application to get PICkit 2 to work under Linux.

Did you read the copyright notice?.
The microchip source code is propietary, they don't allows you to do
*anyting* with it. I wouldn't call it kindly.
Plus, You are talking about the GNU/Linux OS. Linux is only the
kernel.

To Mario: you have your interpretation of the license. To me it is good enough for most users unless you are a GPL purist. I am an OS neutral guy.
And I do not like to use GNU/Linux as Linux is the more often used generic name for both the kernel and the distros.
You are of course free to refer it as GNU/Linux.
