[avr-chat] debug using gdb for AVR in Linux. missing .s temporary files

[José Vallet]

Hello all.

I am trying to debug one simple application under Linux (Kubuntu 6.06) 
using gdb, avarice and an ATJTAGICE mkII. I have a strange problem.

I use the compiler flags "-gstabs -ggdb" to generate the debug info, and 
the process compiles without problems. Here goes the compilation output 
(just in case)

------------------------
address@hidden:~/ethernut-4.2.1/nutapp/lcd-test$ make
avr-gcc -c -mmcu=atmega128 -Os -fno-delete-null-pointer-checks -Wall 
-Wstrict-prototypes -Wa,-ahlms=lcd-test3.lst -DETHERNUT2 
-D__HARVARD_ARCH__ -O0 -gstabs -ggdb 
-I/home/jose/ethernut-4.2.1/bld/include 
-I/home/jose/ethernut-4.2.1/include  lcd-test3.c -o lcd-test3.o
lcd-test3.c:16: warning: 'serial1' defined but not used
avr-gcc lcd-test3.o -mmcu=atmega128 
-Wl,--defsym=main=0,-Map=lcd-test3.map,--cref 
-L/home/jose/ethernut-4.2.1/lib -Wl,--start-group 
/home/jose/ethernut-4.2.1/lib/nutinit.o -lnutarch -lnutos -lnutdev 
-lnutos -lnutcrt  -Wl,--end-group -o lcd-test3.elf
avr-objcopy -R .eeprom -O ihex lcd-test3.elf lcd-test3.hex
--------------------------------

But if I try to load the .elf file in the gdb it complains about a 
missing temporary file...

--------------
address@hidden:~/ethernut-4.2.1/nutapp/lcd-test$ avr-gdb lcd-test3.elf
...
(gdb) list
1       /tmp/ccZFY2vd.s: No such file or directory.
         in /tmp/ccZFY2vd.s
(gdb)
--------------------------

Using "objdump -d" I can see that there are many other temporary files
referenced by lcd-test3.elf that "should" be in the /tmp folder, but
they are not.
---------------
address@hidden:~/ethernut-4.2.1/nutapp/lcd-test$ objdump -g lcd-test3.elf |
grep /tmp
/tmp/ccZFY2vd.s:
/tmp/ccRwY0Qt.s:
/tmp/ccY4Asdx.s:
/tmp/ccsFRQaz.s:
/tmp/ccYLuMmf.s:
/tmp/ccuvqlth.s:
/tmp/ccyKhAeh.s:
/tmp/cctCfg1d.s:
/tmp/ccjpYdT3.s:
/tmp/cckas0z4.s:
-------------------

Has anybody experienced this problem before? Any suggestions?

Is anybody being able to debug code under Linux with an JTAGICE device?

Regards
