GPUTILS is a collection of tools for the Microchip (TM) PIC microcontrollers. It includes gpasm, gplink, and gplib. It's distributed under the terms of the GNU Public License. There are other GNU PIC tools available such as gpsim, a gputils compatible simulator.
I am looking for a free, and possibly open source C compiler for PIC. I might go without C, but I would like to get both options. There are various compilers out there, but since I have never done PIC development before, I am looking for user experience and advice. I am targetting the PIC16F88x family. Here ‘CCS C compiler’ is selected for the PIC microcontroller, then select the ‘browse’ option from the project wired window to select the ‘ccsloader’ in the PICC folder from the program files. A folder with the name ‘source group’ is created in the ‘target’ folder. A fully featured compiler for the PICBASIC language to program PIC microcontrollers is available from meLabs, Inc. Mikroelektronika offers PIC compilers in C, BASIC and Pascal programming languages. A graphical programming language, Flowcode, exists capable of programming 8- and 16-bit PIC devices and generating PIC-compatible C code.
GPUTILS was created by Craig Franklin and James Bowman. Currently, it is primarily supported by Molnár Károly. Until recently has been supported Borut Ražem. In the past it has been supported by David Barnett, Scott Dattalo and Marko Kohtala .
Linux (and other unixes), Mac OS X, and MS-Windows are supported. GPUTILS will compile natively on Linux using gcc. Mac OS X users will need the December 2001 Developer Tools. Windows 98/NT users will need MinGW32 if they wish to compile the tools.
See the Sourceforge download page for source and binary packages.
The latest development sources are available from our svn server.
The following commands will checkout all of the sources and place them in a gputils subdirectory:
Users have ported gputils to many other platforms. Some of these binaries are for the old gpasm package. If you have generated a binary of gputils please notify the maintainer of this website, so that it can be added.
Microchip offers an integrated development environment called MPLAB. This environment is only available for MS-Windows. The gputils project has developed an MPLAB plugin. With this plugin, gputils-mplab, MPLAB can be used as an IDE for gputils.
Microchip provided the project with a set of test files that they use to test MPASM for each release. These files were reformatted, some typos were fixed, and scripts to run the tests were generated. The files and scripts are located in svn and can be accessed here.
For anyone interested, the original unaltered files are available in this archive. For information about the archive please read this file. These files were provided by Microchip without any warranty or any level of support. If you have a question about the files ask the current gputils project administrator, not Microchip.

Aug 21, 2016 -- gputils-1.5.0 Released
Several pre-defined constant and variable in the gpasm.
Extension of error and messg directives: These directives - inside of the parameter string - recognize and execute the #v() macro.
New directives: __badrom, assume, elif, elifdef, elifndef
New gplink feature: Remove the unnecessary banksel and pagesel directives.
The errorlevel directive accept number ranges. E.g. +303-310 or -303-310
The gpvo utility use the disassembler to decode the program memory sections.
The gplink save the local RAM symbols to COD file.
The '.direct' directive - inside of the parameter string - recognize and execute the #v() macro.
The length of source file names in COD file, now 256 bytes long instead of 64 bytes. The gpvc utility thereafter also able to correctly detect the shorter names.
The inc and lkr files are synced with MPLABX 3.35

chipKIT compiler for PIC32 MCUs
The chipKIT™ platform includes 32-bit-microcontroller-based development boards and a software development environment that is compatible with many existing Arduino™ code examples, reference materials and other resources. The multiplatform IDE, known as MPIDE, works with existing Arduino boards as well as the PIC32-based chipKIT boards. It also includes a free, open-source chipKIT C/C++ compiler for PIC32 MCUs. Visit http://www.chipKIT.org for more information on the chipKIT platform. This project includes a build script, designed to run on Mac OS X, that builds the chipKIT compiler for Mac, Linux x86, and Win32 for inclusion in the chipKIT MPIDE release. However, you can use the script to build a standalone compiler and you do not necessarily have to use it with MPIDE. The source for this project is hosted on github.com. To run the build script, follow the instructions given on the build script project page.

C Compiler For PIC32 MCUs
Ccs Pic C Compiler
The 'ccompiler4pic32' project is a community build of Microchip Technology's GCC (GNU Compiler Collection) based MPLAB® C Compiler for PIC32 MCUs. This is a cross compiler that allows you to build C projects targeting Microchip's PIC32 family of 32-bit embedded microcontrollers on your Windows, Linux, or Mac OS X host machine.
