edit: ok, i wont give up.
i tried to set this up in codeblocks, but that doesnt work well either:

edit: i just fired up msys, navigated to the same path eclipse suposedly does (2-environment-cd D:/work/ludum-dare/Debug), set the same parameters (except 5-enable-pretty-printing since gdb-python doesnt seem to know that setting) and finally sourced .gdbinit It didnt even wince at doing that. no errors at all.
does anyone know how to find out what eclipse is trying to run when i click on debug?
Also i just tried the "standard create process launcher" which at first went smoothly, but scrolling up in the traces console, i saw it simply skips over the errors encountered in the python file.
edit: i just realized that not setting 5-enable-pretty-printing doesnt set _use_gdb_pp in printers.py, so it wont run the same way as in eclipse anyhow.
I guess pretty printing is broken in mingw+eclipse cdt
after following these steps: https://stackoverflow.com/a/14266862/3239702 i am facing the following output in eclipse:

Version: Kepler Service Release 1 Build id: 20130919-0819
my mingw installer is all updated, and gdb-python27 is installed from:
gdb-python-7.5.1-mingw32-bin.tar.lzma python 2.7.6 32bit User Environment Variables:
PYTHONHOME = C:\Python27 PYTHONPATH = C:\Python27\Lib PATH = c:\mingw\bin Global Environment Variables: contains much more, i only post the relevant part:
PATH = C:\Python27\; edit: i just tried the python scripts from svn ( svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python ) of course i changed the path in my .gdbinit accordingly. the output in the "gdb traces" console is mostly the same, except for a couple of line numbers which differ, but the errors in those lines are identical, so i supose there just was some refactoring or something like that going on.
and also my .gdbinit file as it is now. before the svn checkout, the commented line was used instead of line 4:
python import sys # sys.path.insert(0, 'C:/MinGW/share/gcc-4.8.1/python') sys.path.insert(0, 'D:/work/libstdc++-v3/python') from libstdcxx.v6.printers import register_libstdcxx_printers register_libstdcxx_printers (None) end edit: tried to debug that printers.py script: i added some prints to the register_libstdcxx_printers function:
def register_libstdcxx_printers (obj): "Register libstdc++ pretty-printers with objfile Obj." global _use_gdb_pp global libstdcxx_printer print("initialy obj: " + str(obj)) print("_use_gdb_pp: " + str(_use_gdb_pp)) if _use_gdb_pp: gdb.printing.register_pretty_printer(obj, libstdcxx_printer) else: if obj is None: obj = gdb obj.pretty_printers.append(libstdcxx_printer) print("after gdb.printing.register_pretty_printer(obj, libstdcxx_printer): obj: " + str(obj)) register_type_printers(obj) the output of this is:
559,740 ~"initialy obj: None\n" 559,740 ~"_use_gdb_pp: True\n" 559,740 ~"after gdb.printing.register_pretty_printer(obj, libstdcxx_printer): obj: None\n" i cant really blame it to not find the attribute 'type_printers' on None, now can i? i suppose that None comes from line 6 in my .gdbinit :
register_libstdcxx_printers (None)
