Thnaks for the fast answer!
I fill really stupid now...
As an extra check I tried to reproduce the problem in order to confirm
the behaviour of the 3 versions of gputils I reported and I could not
reproduce the problem on squeeze.
I still can produce wrong hex files on a standard debian lenny, but not on
standard squeeze.
On standard lenny installation the compilation ends with no
errors/warnings, but when I try to burn the generated hex I get:
...
pulser_1.hex:49:invalid address 0x2008, possibly not hex file for correct
pic type?
...
On squeeze (gputils v 0.13.7 beta) I get quite different hex files
(compared to the one with gputils v 0.13.4) but they burn and run
properly.
I really can not understand what I did different last time I tried
(unfortunately I did not keep a log of what I did exactly).
I am really sorry for having reported this as a bug...
Just in case I am still missing something I attach here the source of the
simple program and two generated hex files.

Hi. Thanks for reporting. I also checked out your report on gputils site.
So you're saying
- gputils-0.13.4 works
- gputils-0.13.5 generates totally different hex, and won't work
- gputils-0.13.7 generates similar hex to 0.13.4, but still won't work
right? Could you provide me the problematic C source code so I can
verify the issue?
Package: gputils
Version: 0.13.7-1
Hi,
I am facing problems compiling c code for pic16f88 since years.
In the beginning I was using an old debian 4.0 32bit system and with sdcc I
was able to get good .hex files.
When I moved to debian 5.0 64bit the .hex generated (still with sdcc) were
broken and my programmer refused to burn them to the pic. The same happens
now with debian 6.0 64bit.
First I thought that the problem was in sdcc, but from hints by sdcc guy and
the last tests I did, I verified the same intermediate .asm files on both
systems (the working one and the non-workgin one) mentioned above (except
some commented lines).
Trying to track the problem I think I found something: on my new debian 6.0
64bit system I can get the correct .hex if I use gputils-0.13.4 compiled
from source.
If I use gputils-0.13.5 compiled from source I get .hex files messed up a
lot.
If I use gputils-0.13.7 compiled from source I get .hex files quite similar
to the ones generated by gputils-0.13.4, but with few lines different, and
they do not work.
I also wrote to gputils bug tracking system almost one month ago, but I
suspect that nobody is taking care of that bugs submissions.
If you need further informations just ask.
Ciao,
Luca
