That's "the one at the htsoft.com website" that I mentioned having no
luck with - I've tried three downloads of it, and all three show the
right number of bytes transferred, but all three barf with a "Verifying
archive integrity...Error in checksums: <10-12 digit number> is
different from <different 10-12 digit number" message, and nothing
installed when I try to execute the install script.

Dunno - Sparkfun electronics sells it - I think it's actually an
"OLIMEX", if the image they're using is accurate.

I haven't created such a beast, but I do know that Xcode can be convinced
to use toolchains other than those provided by Apple. Cocotron, for
example, uses a MingW32-based toolchain to cross-compile Windows apps
from within Xcode. You might try asking those folks how they did it.

If you can run Win32 Console applications OK via a DOS emulator or the
like, look at SourceBoost BoostC. Sorry no Native MAC/Linux versions yet.

The unregistered BoostC PIC18 is limited to 4Kb ROM, 2 banks RAM
non-commercial use. Unlike the competition, the unregistered free mode
does NOT have optimisation disabled.

I know there are people running it on Linux so getting it going on a MAC
shouldn't be too tough. Worst Case, you install on Windows and copy the
command line tools. It runs on any windows from Win98 or Win2K upwards
and isn't a resource hog (full install + optional library source licence
<32Mb and will run under '98 on a PC with only 32Mb RAM - rather less
than their minimum system requirements :-) ) so you don't need the
latest windows emulator.

The licence upgrade process can be done to each tool from the command
line, so if you have the basic setup working and you run out of ROM or
RAM, talk to Dave & Pavel (the SourceBoost team) who are VERY responsive
about what it takes to register the tools on a non windows machine, then
buy a licence.

<http://www.sourceboost.com>

You will find it generates a lot tighter code than the competition and
also includes a full PIC16 compiler and a trial version of the NOVO
cooperative RTOS for PIC16 and PIC18 targets. (Limited
threads/semaphores and cant be reconfigured to reduce resources without
tha licence for NOVO/Library source)

My only interest is I am a happy BoostC user.

I had a look at that, but it didn't seem to understand some standard
C syntax (e.g. "unsigned long int"; insisting that you use "unsigned long"
instead), which meant that it couldn't compile e.g. Microchip's USB
framework.
