What lib am I missing to make GDB shut up?

[ANDY KENNEDY]

All,

The error:

Traceback (most recent call last):
  File "/opt/toolchains/mips/mips/mips-linux-gnu/sysroot/lib/libstdc++.so.6.0.15-gdb.py", line 59, in <module>
    from libstdcxx.v6.printers import register_libstdcxx_printers
ImportError: No module named libstdcxx.v6.printers
Stopped due to shared library event


I've looked around and found that this has something to do with the
Python "pretty print" libraries.  Now, granted, I'm working off a
(relatively) very old CrossTool-NG, however, I'm not above updating
if that is the fix.

Any ideas why I'm getting such an error?

Thanks,
Andy

cd $HOME
svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python

in .gdbinit add the path to it

python
import sys
sys.path.insert(0, '~/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

Does that help

Cool!  Thanks for the help.  I don't actually use Eclipse (I'm a
vim/command line guy myself), but the guys that use it will
appreciated it I'm sure.

Thanks for the info!.

It should be installed along with gcc in:
  ${prefix}/share/gcc-${gcc_version}/python

At least, it is on my gcc-4.6.1 toolchain:
 $ arm-unknown-linux-gnueabi-gcc --version
 arm-unknown-linux-gnueabi-gcc (crosstool-NG hg_default@2503_b5541f296b92 -
  20110604.14-yem) 4.6.1 20110506 (prerelease)

Maybe we could have gdb automatically locate this? Or prepare a template
.gdbinit that the user could install?

Yann E. MORIN.

That is where they are running gdb from.

The only problem we had with your script is '~/python' didn't
evaluate to anything, but that is an easy work-around to fix 
another day.

Thanks for the help!

That could be useful.  If you or someone has the time to do it.

I don't know if I would be able to do it for all cases, but I do
have to prepare one for our case here.  I have lots on my plate
right now or I'd volunteer to do it.

yes you have to use absolute path.

They are the mystical people that use Eclipse. . . ppl I work with.
I'm the only odd-ball here.  I don't like a GUI IDE.  I also only
work with the kernel, RFS, and compiler.  I don't use debuggers that
much, though, I do (as the compiler guy) have to build one that works
for them to use.  I mean, do you want names? ;)

Okay, not a problem.  Unless someone adds it into CTNG, I can throw
something into my build system go generate a file like that.

Again,
Thanks for the help!

I've just pushed #2651341cc084 which installs a template gdbinit in:
    ${prefix}/share/gdb/gdbinit

Care to see if that fits?
