Issue using clang parsing in python

Clang Frontend
#1

Hello,

I am trying to parse c file using clang. I have created python binding using libclang.so and passing my .c file as and argument to my python script.

I see that it is not able to parse header file, due to which file linux/errno.h is also not parsed and hence it is not able to get values of macro definition of all error codes.
Ex:

#2

Not able to parse header files, or not able to FIND (the correct!)
header files? There is a distinct difference... Maybe you could output
the preprocessed data from libclang (using the -E option)

Hi,

Thanks for your help,

I am passing header files in args option of parse function.

tu = index.parse(sys.argv[1],list_arg)

where list_arg = [’-I/usr/include’,…] --all libraries which i will require.

When I parse .c source file to read all return values of a function using “node2.get_tokens().next().spelling” , it is not able to find correct value of macro which is defined in library included in .c file and passed in args during index.parse().

For Example

static int bcm63xx_wdt_open(struct inode *inode, struct file *file)
{
if (test_and_set_bit(0, &bcm63xx_wdt_device.inuse))
return -EBUSY; // not able to find value of EBUSY,hence returns error when I try to print node.spelling()
} // EBUSY is defined in linux/errno.h which is included in my .c file and also passed in list_arg.

Thanks again for all your help,
