Hi-
Has any one ported this (yet)?
If not, is anyone interested in porting it?

Have a look at SDCC for PIC18.
For technical reason GCC cannot be ported to a PIC18 target....

The only technical reason I know is the skill of the programmer performing
the port. Instead, you could say that for 'practical' reasons it's
difficult to port GCC to the PIC architecture and that SDCC is more
suitable. When I first started the SDCC PIC port a few years ago, one of
the reasons I chose it is because the GNUPIC tools already had support for
an assembler, linker, and debugger. Targetting GCC would mean that a good
portion of those would have to be recreated. (I know, technically you
don't have to port gas and ld too, but to be consistant with the tool
chain it's a good idea).

I haven't performed any serious work with on SDCC in the last year and a
half. I had taken to what I say would be 'alpha' level. Most of the basic
stuff worked just fine. Since then, Vangelis Rokas has started a pic16
port ( a sort of fork from the pic14 port). A few people have patched the
pic14 port to work better with gplink. The last timed I tried the SDCC pic
port, I was disappointed to see that the regression tests no longer pass.
In fact, the compiler generates garbage. So now I'd say it sits in
pre-alpha (operand types are no longer processed correctly for some
reason). I don't know about the state of the pic16 port.

I don't have any major near term plans to fix SDCC.

If I did, this is what I'd do:

1) fix the current regression tests
2) move the pcode optimizer to the linker
3) move the call tree analyzer to the linker
4) move the register allocation to the linker

Hi Scott-
Well, I thought that I would probably concentrate on the 18F series from
now on, and therefore, maybe a C compiler would be a good thing.

So, do you think it is worth the effort for us to persue an 18F port (it
should be more straight forward than the 14 and 16 series port)?

And, if so, would it be better to concentrate on GCC or SDCC?
David

I am using the PICC18 from Hi-tech for the 18F series. They did a good job, and really is the #1 choice for commercial choice. But for hobbies, I really want to see a free available GCC based PICC18 platform C and C++ compilor comes out in next 2 years.

There is only one problem with this scheme, you cannot apply the update to
the non-registered version :(((

Yah I agreed. We can't just reinstalled. The software are able to detect

HI-TECH PICC and PIC18 also has full (well, almost full) demo versions
available. The compiler has some delays, some commandline options are
missing and you don’t get the source to the libraries.

"Easilly cracked" is NOT the same as "Free."

I can think of two better ideas:

 1) Buy the compiler

 2) quit the project your working on and help Vangelis finish the PIC16
port of SDCC.

The first option assumes your project is making money whereas the second
doesn't. I'll be surprised if anyone will (publicly) assist you in
stealing software.

I'm not convinced that running SETUP.EXE constitutes being easily
cracked!

My belief is that Microchip know full well that the C18 compliler is
actually free, and having a free C compiler encourages people to use the
processors = sells more silicon for uChip. Yet, by not overtly
publishing the availability of a free compiler, uChip don't upset the
3rd party compiler vendors too much. Further, any bona-fide company will
purchase the C18 compiler, or a 3rd party compiler product to be able to
get support, updates etc. So, everyone benefits. uChip sell silicon, the
compiler vendors still sell compilers to professional developers, and
the hobby community gets a free C compiler for the PIC18. Win win win.

I've had no problems re-installing the C18 compiler after the 60 days, I
don't even have to "uninstall" the previous version, simply write on top
of it....  It even leaves my other additional libraries in place rather
than wiping out the folders....

What version of the demo are you using?....I've got 2.20ad.

I've heard many excuses for not paying for software, but that's quite
original.

You believe that Microchip are giving the compiler away, despite the fact
that they charge $450 for the non time locked version?

I use InCtrl5. The following is taken from the Help File:

--- CUT HERE ---
InCtrl5 records a "snapshot" of your system before the install utility runs. Afterward, it records another snapshot, compares the two, and reports the differences in HTML format, plain text, or comma-separated values format. Click here for help with the program's main form, or here to learn about the process of tracking an installation.

InCtrl5 is the fifth incarnation of one of PC Magazine's most popular utilities, and naturally has a number of new features. InCtrl5 was designed for and tested under Windows 95, Windows 98, Windows ME, Windows NT4, and Windows 2000. Unlike InCtrl4, it does not support Windows NT 3.51. It will not run under any any other operating system - if you try, it will warn you of incompatibility and all of its controls will be disabled. If that happens, check the PC Magazine web site to see if an update is available.
