I update my SDCC CVS source and the build process is indeed working
quite nicely. Thanks a lot.
For PIC14 support, I also follow Martyn Welch's fix for
in the "Setting up PIC header files" setion. The URL is
again listed here.
http://ubicomp.lancs.ac.uk/~martyn/sdcc_linux/
With the latest SDCC and GPUTILS, I can build all the sample programs
using the simple command form for both PIC14 and PIC16. Last time, it was
broken for PIC14.
The warning message is normal since they are not processor specific
(hopefully).
The hellotty1.c is a simple fix of David McNab's sample program hellotty.c
(simply
adding "#pragma stack 0x200,64" ) used to be at
http://www.freenet.org.nz/sdcc.

Xiaofan

I've worked out what I think is a better build process for sdcc that
installs everything properly. Can you can try it out for me ? I've used
it on a couple of my machines so far and it's worked fine. I think the
comments in David's HowTo about manually moving some files at the end
are now wrong because it seems the make files have been improved to do
it all automatically now. BUT I've not tested all the libs yet.
./configure --disable-mcs51-port --disable-gbz80-port --disable-z80-port
--disable-avr-port --disable-ds390-port --disable-ds400-port
--disable-hc08-port --disable-xa51-port
make
su -c "make install"
cd device/lib/pic16/
./configure
make
make lib-io
cd ..
make model-pic16
su -c "make install"
