* python support is needed for providing finer scripting control
in gdb, and for remote controling gdb for example from qtcreator
* gdb/configure tries to autodetect python using python executable
with --includes --ldflags --exec-prefix to get the right flags
As it's difficult to achieve in OE's context, we generate a
script which will return the right values and make gdb's build
system happy. This idea was taken from the following article :
http://www.mentby.com/doug-evans-2/python-enabled-gdb-on-windows-and-relocation.html
* tested using angstrom & armv7 target & qtcreator 201005 & 2.4.0

Hi Eric,

Can you submit the patch against qt layer or meta-oe instead of oe-core, since python enabled gdb shouldn't be turned on by default in oe-core based on its usage, qtcreator, etc.

Thanks,
Jessica

I can submit that to meta-oe (as qt is inside oe-core) but having a gdb with 
python can
also make sense in oe-core as this is not dedicated to qtcreator but gives 
very good scripting capabilities to debug with gdb :

Hi Eric,

Yes, understand the usage and advantage, but still think apply the patch in meta-oe first then if later on there's strong demand for this feature we can pull into oe-core is the right approach.

Thanks,
Jessica

what are your reasons for it to not be in oe-core/master ?
python support is useful in gdb even on commandline
Or are you aware of any bugs that will destabilize gdb ?

I think there are going to be two groups of people on this, the people
who want it and the people who don't. How about a PACKAGECONFIG option
for this?

I suspect over time the request will come in for gdb itself too which is
why I'm thinking ahead to that...

Cheers,

Richard
