compiling 1394 error?

zongtongyi · 04-07-2006, 10:45 PM

I have making a projet -TCP/IP transmitting based on IEEE1394.That is packeting the data using TCP/IP
stack and transmitting the packets using IEEE1394 device driver.
I have realised the TCP/IP stack and 1394 interface,then make it and met problems.

This is the errors,compiled by gcc-3.2.2

Well "previous declaration" errors normally mean that you are including the header file too many times.

Or maybe it could be defined in the header file and again in the C file. If graemef is right, try wrapping your .h file in an ifndef macro, like:

Code:

#ifndef _MY_1394_H
#define _MY_1394_H

... /* defs go here */

#endif

If it's the latter problem (redefined in .c file; it looks from your errors that this is the case) then only use the C file for the implementation, not the definition. For example, function definitions like

Code:

void foo(int x);

go in the header and function implementations like

Code:

void foo(int x) {
    printf("%d\n", x);
}

go in the C file.
