- Ported the SWIG wrapper shell scripts to Python so that they would work on Windows too along with other platforms - Updated CMake handling to fix SWIG errors and manage sym-linking on Windows to liblldb.dll - More build fixes for Windows The pending issues are that two Python modules, termios and pexpect are not available on Windows. These are currently required for the Python command interpreter to be used from within LLDB. llvm-svn: 212111

# 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

|
