Post by thread:[PICLIST] GNU GPL C compiler for PIC

Has anyone writen a free compiler for PIC that runs on Linux and is licensed under the GNU GPL? I have some students that want to make a project and then share the code and hex files after. I use the Hi-Tech compiler but I don't think the free version runs on Linux and I don't think you are allowed to share the hex file made from the free compiler. Solutions? -- Roy Souther <spam_OUTroyTakeThisOuTsilicontao.com> http://www.SiliconTao.com Windoze users are hopeful, Linux users are confident. -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

Roy, I'm actively working on porting SDCC to the PIC midrange architecture. You can checkout a brief history of my efforts: http://www.dattalo.com/gnupic/sdcc.html SDCC's homepage is here: http://sdcc.sourceforge.net/ As I've told others, the rate at which I'm progressing I'll probably have a beta quality compiler by March '02. Right now, you can grab what's in CVS and experiment with variations of the code that is working. In the CVS tree, I've created: sdcc/src/regression/*.c These contain numerous C files for testing new features as I add them. You can see this on line at: cvs.sourceforge.net/cgi-bin/viewcvs.cgi/sdcc/ http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/sdcc/sdcc/src/regression/ Some of the major things working are: addition, subtraction, <<, >>, ^, comparisons, for loops, case statements Some of the things partially working: Parameter passing to functions, returning parameters from functions, structures, signed operations, pointers, code banking, register banking. Some of things that don't work at all: multiplication, division, %, 32-bit types, floating types Some of the exotic stuff that works: Post code optimization, call stack tracing, dynamic register allocation, Some of the important stuff outside of the immediate scope of the C compiler that doesn't work: Object file support/linking, library generation (e.g. code for uarts or I2C), Processor specific include files.
