<br>
Ok so I did end up reconfiguring it and rebuilding but that
was no help . I then realized that I was importing
python27.dll as well as python27_d.dll . When I rebuilt
liblldb I started getting an single unresolved error for <br>
imp_Py_InitModule which I guess was the symbol for the
Py_InitModule4 python api which is actually a macro which
is defined depending on a few flags . So I ended up
rebuilding python27 and the unresolved error went away and
built everything from scratch . The good news is that when I
invoke the 'script' command in the lldb interpreter it
doesn't crash anymore and I can use the python interpreter .
I can even import the lldb module without getting the
embedded interpreter Import error . However I when I
actually import lldb from a python module and run it with
the standalone interpreter I still get the Import Error. I
have checked the PYTHONPATH which was different for the lldb
embedded interpreter and updated the variable to contain the
missing paths but no cigar <span><span> :-( </span></span>.
Any suggestions ?</div>

for the response , sorry for the delay. As
a matter of fact I actually got rid of the
system python and installed my custom
version. I do suspect it is a linking
problem though. When I build liblldb.dll it
always loads python27.dll instead of
python27_d.dll. Do you happen to know where
the python27 lib is specified as an input
library because the project properties in
liblldb does not specify it . however the
linker complains if I don't specify the lib
directory in 'additional directories' and
when I do it always links to the
python27lib. I grepped the whole build
directory and two files
SystemInitializer.obj and LLDBWrapPython.obj
seem to contain /DEFAULTLIB:python27.lib. Do
you have an idea of what is causing the
compiler to do this ?</div>

thanks for the reply , I did
use MSBUILD as Ninja didn't
work for me on my system.
As far as the _lldb_d.pyd
file is concerned it is
stored in the same place.
and it is being used by
lldb.py because everything
else works besides the
embedded_interpreter. That
is I am able to use the api
from python it is just that
interpreter issue that comes
up . <br>

python2.7.10 using

it.<br>
