2015-05-01: master branch works with libclang-3.7 HEAD
The requirement on python-clang-3.7 means that you either need:
- to install libclang1-dev to get libclang.so
- create a link to libclang-3.7.so.1 named libclang.so
- hardcode the required clang.cindex.Config.load_library_file in your code
Stable Distribution is available through pypi at https://pypi.python.org/pypi/ctypeslib2/
sudo pip install ctypeslib2
See the LLVM Clang instructions for dev branch 3.7 at http://llvm.org/apt/
sudo apt-add-repository "deb http://llvm.org/apt/raring/ llvm-toolchain-raring main"
sudo apt-get install libclang1-3.7 python-clang-3.7
sudo echo `echo "/usr/lib/llvm-3.7/lib/" >> /etc/ld.so.conf.d/llvm-dev.conf`
sudo ldconfig -n
usage: clang2py [-h] [--debug] [-c] [-d] [-k TYPEKIND] [-l DLLS] [-o OUTPUT]
[-r EXPRESSION] [-s SYMBOL] [-v] [-w W] [-m module]
[--preload DLL] [--show-ids SHOWIDS] [--max-depth N]
files [files ...]
generate python ABI code from C code
positional arguments:
files source filenames
optional arguments:
-h, --help show this help message and exit
--debug setLevel to DEBUG
-c include source file location in comments
-d include docstrings containing C prototype and source
file location
-k TYPEKIND kind of type descriptions to include: d = #defines, e =
enumerations, f = functions, s = structures, t =
typedefs
-l DLLS libraries to search for exported functions
-o OUTPUT output filename (if not specified, standard output will
be used)
-r EXPRESSION regular expression for symbols to include (if neither
symbols nor expressions are specified,everything will be
included)
-s SYMBOL symbol to include (if neither symbols nor expressions
are specified,everything will be included)
-v verbose output
-w W add all standard windows dlls to the searched dlls list
-m module Python module(s) containing symbols which will be
imported instead of generated
--preload DLL dlls to be loaded before all others (to resolve symbols)
--show-ids SHOWIDS Don't compute cursor IDs (very slow)
--max-depth N Limit cursor expansion to depth N
About clang-args: You can pass modifier to clang after your file name. For
example, try "-target x86_64" or "-target i386-linux" as the last argument to
change the target CPU arch.
- clang2py is a script that calls ctypeslib/ctypeslib/clang2py.py
- clang2py.py is mostly the old xml2py.py module forked to use libclang.
- clang2py.py calls ctypeslib/ctypeslib/codegen/codegenerator.py
- codegenerator.py calls ctypeslib/ctypeslib/codegen/clangparser.py
- clangparser.py uses libclang's python binding to access the clang internal representation of the C source code. It then translate each child of the AST tree to python objects as listed in typedesc.
- codegenerator.py then uses these python object to generate ctypes-based python source code.
Because clang is capable to handle different target architecture, this fork {is/should be} able to produce cross-platform memory representation if needed.
This fork of ctypeslib is mainly about using the libclang1>=3.7 python bindings to generate python code from C source code, instead of gccxml.
the original ctypeslib contains these packages:
ctypeslib.codegen- a code generatorctypeslib.contrib- various contributed modulesctypeslib.util- assorted small helper functionsctypeslib.test- unittests
This fork of ctypeslib is heavily patched for clang.
