hi all,
i have a C header file named by linux.h which contains the following section of code:

Code:

#define USBI_BUS_PRIVATE \
	char filename[PATH_MAX + 1]; \
	struct usbi_device *dev_by_num[USB_MAX_DEVICES_PER_BUS];

and another header file named by usbi.h which includes the linux.h header file and here is a piece of code:

Code:

struct usbi_bus {
  struct list_head list;

  pthread_mutex_t lock;

  libusb_bus_id_t busid;
  unsigned int busnum;			/* Only needs to be unique */

  struct usbi_backend_ops *ops;
  int io_pattern;

  struct list_head devices;
  struct usbi_device *root;

  USBI_BUS_PRIVATE
};

watch the red line.

when i try to compile this usb package i got the following error:

expected specifier-qualifier-list before 'USBI_BUS_PRIVATE'

can anyone please how to fix this error?

thanks in advance.

Could you please post the actual error messages + a couple of lines before.

My guess is that the .h file that contains the define was not found, but it's just a first guess given the above information.
