Thanks a lot. It solved the issue partially. I could enable the python
scripting in GDB. But still the STL containers are not printing data.
It worked straight in debian. The following log (Cygwin) explains
more:

(gdb) python print 10
10
>>>Python is
enabled
(gdb) print myList
$1 = {<_List_base >> = {
_M_impl = { >> = { >> = {}, }, _M_node = {
_M_next = 0x681838, _M_prev = 0x6818c8}}}, }
 >>>libstdc++ printer is not used
(gdb) python print myList
Traceback (most recent call last):
  File "", line 1, in 
NameError: name 'myList' is not defined
Error while executing Python code.
   >>>I will ask in archer list.
(gdb)

But I dont know whether it has some thing to do with Cygwin. I will
ask in archer mailing list too. Mean while if anyone has some clue,
please share.

Can you get configure to add "-L/usr/lib/python2.5/config" when linking?
I think the following should work:

$ LDFLAGS=-L/usr/lib/python2.5/config configure ...

Does this solve the problem?

Yes. I have python 2.5 installed using Setup.exe. In debian I had the
same issue with python enabled GDB. But I could solve it by installing
the python2.5-dev development packages. I had a look at the files
included in cygwin package (you mentioned) and the files in
python2.5-dev deb package:
http://packages.debian.org/lenny/i386/python2.5-dev/filelist

The observation is that python static library (in case of linux-
libpython2.5.so in /usr/lib/) is missing in cygwin and that is exactly
what gcc is complaining when building gdb (please refer to the config
log in my previous post). I dont know whether this is handled
differently in cygwin. Please give your suggestions.

I further investigated and found in config log that gdb build is not
detecting python in cygwin. The following log from config.log:

configure:11376: checking for python2.4
configure:11396: gcc -o conftest.exe -g -O2conftest.c -lncurses
-lz -lm   -lpython2.4 >&5
conftest.c:49:30: python2.4/Python.h: No such file or directory
...
configure:11240: checking for python2.6
configure:11260: gcc -o conftest.exe -g -O2conftest.c -lncurses
-lz -lm   -lpython2.6 >&5
conftest.c:49:30: python2.6/Python.h: No such file or directory
...
configure:11308: checking for python2.5
configure:11328: gcc -o conftest.exe -g -O2conftest.c -lncurses
-lz -lm   -lpython2.5 >&5
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
cannot find -lpython2.5

'make all install' log gives:
checking whether to use python... auto
checking for python2.6... no
checking for python2.5... no
checking for python2.4... no

This is probably because python development packages (Equivalent to
python2.5-dev deb package) are not installed. Unfortunately it is not
available for cygwin. Is there any other way to solve this issue?

Thanks,
Sreejith
