gdb-avr is outdated

[Dmitriy Geels]

Binary package hint: gdb-avr

gdb-avr in ubuntu jaunty/karmic is outdated.

gdb package has version 6.8-3ubuntu2, while gdb-avr is still 6.4.90.dfsg-2.1 since intrepid.
please update gdb-avr package to latest gdb source.

[Artur Rona (ari-tczew)]

Could you give a link to source code?

[Dmitriy Geels (dmig)]

Eh... do you mean gdb source? http://www.gnu.org/software/gdb/download/
As I understand, gdb-avr may be built even from gdb package source.

[Dmitriy Geels (dmig)]

avr-gdb may be manually updated from gdb source:
apt-get source gdb
cd gdb-6.8
./configure --prefix=/usr/local/avr --program-prefix="avr-" --target=avr --disable-werror
make
make install

 --disable-werror is requred, gdb doesn't build without this.

Please tell me, what information you need?

Package gdb-avr is outdated!
It is still 6.4.90.dfsg-3ubuntu1 in Ubuntu Lucid, while gdb is already 7.0.90.20100311-0ubuntu1!

gdb-avr may be easily built from source of gdb package -- so, why not update it in repository?

[Alessio Igor Bogani (abogani)]

Because no one report that it works.

Could you provide a 1) build log and a 2) working debug session log, please?

Thanks a lot!

[Dmitriy Geels (dmig)]

Here is complete build log, I will attach debug session log later. I use gdb-avr for debugging from eclipse, so I have to learn, how to use gdb itself.

avr-gdb 6.4 has a bug which prevents its use under Eclipse. This update is badly needed.

See http://avr-eclipse.sourceforge.net/wiki/index.php/Debugging which documents the point of failure on the gdb console as follows:
<<<
46-data-list-changed-registers
46^done,changed-registers=["26","28","29","30","32","33","34"]
(gdb)
47 info sharedlibrary
&"info sharedlibrary\n"
48-gdb-exit
>>>

My system is: Linux ##### 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux

Here is my duplication of the above running avr-gdb from Eclipse under Lucid with a simple program to flash LEDs.
<<<
299-data-list-changed-registers
299^done,changed-registers=["17","26","27","28","29","30","31","32","33","34"]
(gdb)
300 info sharedlibrary
&"info sharedlibrary\n"
301-gdb-exit
>>>

I followed Geels' instructions above (thanks Dmitriy). Here is the version response after a successful build.

$ /usr/local/avr/bin/avr-gdb -v

GNU gdb (GDB) 7.1
<snip>
This GDB was configured as "--host=x86_64-unknown-linux-gnu --target=avr".
<snip>

The build log is attached, as well as a successful Eclipse session log with 7.1 just built, which did NOT work with 6.4 as stated in my previous post. Both logs are redacted of local information with ##### strings. Apologies for not turning off my zsh RPROMPT while running script.

[Appears I can only do one attachment per post. Session log will follow.]

[Allan (allan-stokes)]

Here is the successful Eclipse session log running under the freshly build avr-gdb 7.1
