FP - How to process includes properly about ctypeslib

[XVilka]

If you can point me in the place in the code where it handled - I can try to fix/improve by myself. Thank you!

that seems to be an llvm/clang error message. the most probable explanation is that the include path does not contain the user headers' include folder.
try using --clang-args="-I/usr/your/path/to/headers/files/" ?

[XVilka]

added those, doesn't seem to help. See how I did it in my script http://xvilka.me/genbind.py.txt

[trolldbois]

I confirm it's an include path issue.
@XVilka try clang_opts = ["-I/usr/local/include/libr/", "-I/usr/local/include/", "-I/usr/local/include/libr/include"]

From a clean radare2 git repo I was able to make the "angled error" disappear:

radare2$ clang2py ./libr/include/r_core.h --clang-args="-I ./libr/include/"

I do not know where your libr includes are installed, but if you add the folder containing r_userconf.h to the Include path, it works.

[XVilka]

@trolldbois all files are located in /usr/local/include/libr/, both r_core.h and r_userconf.h.

[trolldbois]

XVilka, try to use clang to parse the radare headers.
clang-5.0 -E libr/include/r_core.h
That usually produces the error you reported because the include path is lacking.
The fix is :
clang-5.0 -E libr/include/r_core.h -I./libr/include/

So when you have a working clang command line, you will have a working ctypeslib command line

[XVilka]

Interesting thing that clang line works for me, while ctypeslib - doesn't.

[trolldbois]

Can you reproduce an error with clang2py ?
Or are you saying your code that uses ctypeslib doesn't work ?
.

[trolldbois]

Your code has the following error:
clangparser.Clang_Parser(flags = [])

Flags should not be empty.

[XVilka]

@trolldbois took a line from your examples.

[XVilka]

@trolldbois yes, if I call clang2py --clang-args="-I/usr/local/include/libr" /usr/local/include/libr/r_core.h everything works OK. Very strange.

[trolldbois]

So if you change your code a bit like this https://gist.github.com/trolldbois/af7fee01b1afa13a74c196fefceeda93 it will work .

The clang parser is the class that need the Include command line options. Not the code generator.
Can you point me to the example you used so I can double check it on my side ?

[XVilka]

@trolldbois Thank you! That indeed solved the issue. Can't find where I saw this, maybe I just misread it...

[trolldbois]

Great !
