For me it works by default (gentoo+gcc-4.7+gdb-7.4)

Okay, I'm really struggling to get these scripts to be found and run by gdb. I really have tried to follow the instructions. Can someone give me an idiots guide to getting this set up. Commands to type, config files to make and menu settings to select. I've honestly tried and need help... Can someone give me a step by step here?

I re-read the log message here:
http://forums.codeblocks.org/index.php/topic,16607.msg112768.html#msg112768
It seems that I can see any command to load the pretty printer for std c++.

You need to add a command: (There is an option in Codeblocks' debugger setting dialog)

Code: [Select]
source /path/to/some.gdb
Note:
The file "/path/to/some.gdb" should contains the script mentioned here:
http://sourceware.org/gdb/wiki/STLSupport
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

ollydbg: this is not needed, becase gdb supports auto loading them...

pureblacksin: try this command in a terminal
Code: [Select]
$ ldd /usr/bin/gdb | grep pyt
It will tell you if gdb is compiled with python support, if the output is empty, then you have no luck.
But I'm pretty sure it will be non-empty.
Also you can search for the printer files, they are python scripts.
See what do I have on my system:
Code: [Select]
/usr/share/gcc-data/x86_64-pc-linux-gnu/4.7.0/python/libstdcxx/__init__.py
/usr/share/gcc-data/x86_64-pc-linux-gnu/4.7.0/python/libstdcxx/v6/__init__.py
/usr/share/gcc-data/x86_64-pc-linux-gnu/4.7.0/python/libstdcxx/v6/printers.py
/usr/share/gdb/auto-load/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.0/32/libstdc++.so.6.0.17-gdb.py
/usr/share/gdb/auto-load/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.0/libstdc++.so.6.0.17-gdb.py
I have these for all three supported compiles I have (4.5, 4.6 and 4.7).

Right first bit had an output of:

Code: [Select]
james@ubuntu:~/python$ ldd /usr/bin/gdb | grep pyt
libpython2.7.so.1.0 => /usr/lib/libpython2.7.so.1.0 (0x00007fd03bcfc000)

I have the first three files in a couple of folders which I downloaded, they are not in those directories, I don't have those directories.

The last two, the closest I can get to that path is:
Code: [Select]
/usr/share/gdb/gdb/auto-loadThis directory terminates, has two .gdb files in it neither of which look like yours.

I tried to run make in the checked out folder where the first three files were, make didn't work. I did this to see if it would generate any files...

Then you should manually download the stl python printer files and to put the loading code in the .gdbinit or another file which you have to source in the initial commands.

Right, I have re-done that. I now have the python files checked out to the home directory, in the home directory I made a file called .gdbinit like I was told and have pointed the file at the python folder, i.e. the one that was checked out.

Now how to I tell the debugger to read the .gdbinit from the home directory... This could be the bit that is going wrong. Also, what file is the .gdbinit file looking for? I might need to let it look deeper into the python, checked out folder.

Try to put "source ~/.gdbinit" in the initial commands in the settings.
C::B uses the -nx command line flag to tell gdb to not read the ~/.gdbinit file by default.

Right, well I got it in:

Code: [Select]
Starting debugger: /usr/bin/gdb -nx -fullname  -quiet source ~/.gdbinit -args /host/James/Ubuntu/C-C++/ParseWords/bin/Debug/ParseWords
done

however -nx is still there, and still no joy, although this looks like an improvement :)

Put the source command in the initial commands field, not the args field...
If it doesn't work, put the initialization code in another file and source it.
You have to see "source my_file.source" command in the log, not in the gdb command line.
