# For the Python script interpreter (external to liblldb) to be able to import
|
|
# and use the lldb module, there must be two files, lldb.py and _lldb.so, that
|
|
# it can find. lldb.py is generated by SWIG at the same time it generates the
|
|
# C++ file. _lldb.so is actually a symlink file that points to the
|
|
# LLDB shared library/framework.
|
|
#
|
|
# The Python script interpreter needs to be able to automatically find
|
|
# these two files. On Darwin systems it searches in the LLDB.framework, as
|
|
# well as in all the normal Python search paths. On non-Darwin systems
|
|
# these files will need to be put someplace where Python will find them.
|
|
#
|
|
# This shell script creates the _lldb.so symlink in the appropriate place,
|
|
# and copies the lldb.py (and embedded_interpreter.py) file to the correct
|
|
# directory.

|
|
# CONFIG_BUILD_DIR is where the build-swig-Python-LLDB.sh shell script
|
|
# put the lldb.py file it was generated from running SWIG.
|
|
# PYTHON_INSTALL_DIR is where non-Darwin systems want to put the .py and .so
|
|
# files so that Python can find them automatically.
