<div class="moz-cite-prefix">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 warning.<br>
<br>
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>
-DLLDB_DISABLE_PYTHON=0

<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
