gnupic: Thread: Debian templates for dsPIC build toolchain 2.01

Hi,

Attached to this email are the templates needed to build debs for GCC and
Binutils corresponding to Microchip's version 2.01 toolchain.

There is not much changed in this release. The main thing which is of more
general interest is a set of general rules for GNU make. This ruleset is
not from Microchip, but was written by me. The file is in the tarball as
pic30-debian-2.01/pic30-support-2.01/pic30-rules.mk. They allow small
makefiles to be written like so:

DSPIC := 30f3013
PROJECT := blinkenlight
OBJS := main.o foo.o bar.o
include /usr/share/pic30-support/pic30-rules.mk

Implicit rules are used to create object files from C or Assembler as
necessary.

cheers,

John

Using my example from before, if you wanted to link in libdsp-coff.a, you
just need to add it to the LDLIBS variable, _after_ the rules file is
included. So the makefile becomes:

DSPIC := 30f3013
PROJECT := blinkenlight
OBJS := main.o foo.o bar.o
include /usr/share/pic30-support/pic30-rules.mk
LDLIBS += -ldsp-coff

Yes, I'm using Breezy myself. The tools should work on any Debian system
though. I used the Debian mingw toolchain as a basis for my files.
