<div>That problem is due to PYTHONPATH not being exported
to the location where the python packages are built.<br>
Similar to Linux, you have to export PYTHONPATH to
build_dir/lib/site-packages/python.<br>
The _lldb.pyd file symlinks to liblldb.dll on Windows.<br>
<br>
Regardles, you would still get an error on the
command-line due to the missing python termios module on
Windows.<br>
In ScriptInterpreterPython.cpp:2628, the termios module
is imported, which would fail immediately.<br>

We have yet to solve this dependency on Windows.<br>
However, we can use the API directly for now.<br>
<br>
AFAIK, these modules are only used for the command-line
interpreter, so does not affect using the API directly.<br>
If we comment out these out, we can run the examples in
lldb/examples/python/, such as globals.py to load an ELF
file and dump the globals using the Python API on
Windows.<br>

<div>Thanks, I'll look into the CMake

For now, you have to enable the variable
LLDB_ENABLE_PYTHON_SCRIPTS_SWIG_API_GENERATION
specifically to use the new python
scripts, when LLDB_DISABLE_PYTHON is
disabled. <br>
Which is why not using the variable would
break the build on Windows. On Linux, it
would work both ways.<br>
<br>
I added this variable so that the new
scripts can be tested without affecting
normal builds on other platforms.<br>
Could you please try,<br>
cmake<b>
-DLLDB_ENABLE_PYTHON_SCRIPTS_SWIG_API_GENERATION=1</b>

<div>Hi,<br>
<br>
I'm planning to
upstream the
Windows Python API
changes now. <br>
<br>
This has been done
by completely
rewriting the
shell scripts used
for the API
generation in
Python so that
it's portable
across different
platforms. We have
tested it on both
Windows and Linux
successfully. <br>
<br>
I have added a new
CMake variable
"LLDB_ENABLE_PYTHON_SCRIPTS_SWIG_API_GENERATION",
to control if the
new Python scripts
for managing SWIG
generating the API
are enabled or
not. This is
disabled by
default to not
impact other
platforms. This
variable can be
removed once we
move all the
platforms to the
Python scripts
from the shell
scripts. There's
some cleanup to be
done, which I'll
be working on.<br>
<br>
Please let me know
if there are any
issues or
comments.<br>
<br>
Thanks,<br>
Deepak
