python - pycparser 解析错误

Question

我正在尝试使用 pyCparser 创建 AST，打印出以下错误:

Traceback (most recent call last):
File "C:\Work\RE\Tools\VarsExporter\BuildExportedDb.py", line 1076, in 
main()
File "C:\Work\RE\Tools\VarsExporter\BuildExportedDb.py", line 1032, in main
ast = parse_file(i_file)
File "C:\Python27\lib\site-packages\pycparser_init_.py", line 93, in 
parse_file
return parser.parse(text, filename)
File "C:\Python27\lib\site-packages\pycparser\c_parser.py", line 152, in 
parse
debug=debuglevel)
File "C:\Python27\lib\site-packages\pycparser\ply\yacc.py", line 331, in 
parse
return self.parseopt_notrack(input, lexer, debug, tracking, tokenfunc)
File "C:\Python27\lib\site-packages\pycparser\ply\yacc.py", line 1199, in 
parseopt_notrack
tok = call_errorfunc(self.errorfunc, errtoken, self)
File "C:\Python27\lib\site-packages\pycparser\ply\yacc.py", line 193, in 
call_errorfunc
r = errorfunc(token)
File "C:\Python27\lib\site-packages\pycparser\c_parser.py", line 1761, in 
p_error
column=self.clex.find_tok_column(p)))
File "C:\Python27\lib\site-packages\pycparser\plyparser.py", line 67, in _ 
parse_error
raise ParseError("%s: %s" % (coord, msg))
ParseError: Objectffly\SerDb.i:43:18: before: __loff_t

出现上述问题的原因是什么？我该如何处理？有什么建议我如何调试它并找出发生了什么吗？

来自 pyCparser git 常见问题解答:

C code almost always #includes various header files from the standard C library, like stdio.h. While (with some effort) pycparser can be made to parse the standard headers from any C compiler, it's much simpler to use the provided "fake" standard includes in utils/fake_libc_include. These are standard C header files that contain only the bare necessities to allow valid parsing of the files that use them.

为了解决这个问题，我已经成功地使用了描述的方法 here .
