autofff's Issues

pip download error

Hi Andreas,

seems like the pip install does not work as expected:

python -m pip install autofff

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\fsc6lr\AppData\Local\Temp\pip-build-r9e4eyy_\validator

It also does not work with a manual installation "python -m pip install ."

I tried with anaconda3 with python 3.6 and a standalone python with python 3.4, both are not working...

Hope you can fix it ;P

Passing Defines during generation

Hello,

First off, thanks so much for this! this is a fantastic project!

I'm running into an issue with some includes where generation fails becuase something is not defined.

for example. from list.h in FreeRTOS:

#ifndef INC_FREERTOS_H
	#error FreeRTOS.h must be included before list.h
#endif

Is there any way i can pass defines into the generator?

Implement clang-based scanner

As discussed in #3 (comment), explore possibilities of using libclang's C API. Fortunately, libclang provides Python bindings for their C API.

Experimenting with it demonstrated, that libclang provides deeper lexical fidelity when parsing a C source/header file (i.e. it provides preprocessor tokens before they're expanded). Perhaps this can be used to more effectively work around __asm__(...)-statements, which make direct inclusion of that particular file impossible.

pycparser version cap

pycparser 2.21 adds an align arg to a bunch of the constructors in

eliben/pycparser@14ffe7b

Which breaks autofff. Pinning pycparser to <=2.20 can resolve this.

Outdated README

I think the instructions in the README regarding how to use autofff as a python package are no longer correct. You mention you can do the following:

import autofff

import os.path

targetHeader = input("Enter the path of the header you would like to scan: ")
outputHeader = input("Enter the path of the target header file which shall be generated: ")
fakes = './autofff/dependencies/pycparser/utils/fake_libc_include'

scnr = autofff.GCCScanner(targetHeader, fakes) # Create GCC code scanner

However, I don't think this works after this commit: 4ba015b. When you no longer do from scanner import * in the __init__.py file, you can't just use autofff.GCCScanner() after doing an import autofff.

I'm no python expert, but I was able to get the following to work:

from autofff import scanner

targetHeader = input("Enter the path of the header you would like to scan: ")
outputHeader = input("Enter the path of the target header file which shall be generated: ")
fakes = './autofff/dependencies/pycparser/utils/fake_libc_include'

scnr = autofff.scanner.GCCScanner(targetHeader, fakes) # Create GCC code scanner

Perhaps there is a better way to do it. All I know is what is listed in the README didn't work for me
