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?
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_baseint, std::allocatorint = {
_M_impl = {allocatorstd::_List_nodeint = {new_allocatorstd::_List_n
odeint = {No data fields}, No data fields}, _M_node = {
_M_next = 0x681838, _M_prev = 0x6818c8}}}, No data fields}
libstdc++ printer is not used
(gdb) python print myList
Traceback (most recent call last):
File string, line 1, in module
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.

Hi,
I could successfully install gdb-archer in cygwin as explained in
link: http://tromey.com/blog/?p=494 , but not able to inspect STL container
object. It looks like the python scripting is not enabled in newly installed
gdb. The following log explains more:
$ gdb a.exe

odeint = {No data fields}, No data fields}, _M_node = {
_M_next = 0x681850, _M_prev = 0x6818e0}}}, No data fields}
(gdb)
When I try 'python print 10' in gdb prompt I am getting error:
(gdb) python print 90
Python scripting is not supported in this copy of GDB.
The archer installation went currectly and I have python installed in my
cygwin. Please help me to resolve this issue.
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

...
configure:11240: checking for python2.6
configure:11260: gcc -o conftest.exe -g -O2conftest.c -lncurses

...
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
