 I/O] on the [emergency operation of the (report code). ! !
Look at code :
#include<stdio.h>;
#include<stdlib.h>;
#include "Sys/io.h>;
#include "Linux/ioport.h>;
Int base=0x210; //base address
Int X :
Int main ()
{
X=check_region (0x210,0x8);
If (x==0)
{
Request_region (0x210,0x8 "AC1082");
Int nDI;
NDI=inb (0x216);
}
Else printf ( "ERROR");
Return 0
}
I want to I/O operate, I wonder if the above in the right way?
In translation, suggested that the following errors :
/tmp/ccqsb5EC.o (. Text+0x1b) : In function `main ':
: Undefined reference to `ioport_resource '
/tmp/ccqsb5EC.o (. Text+0x20) : In function `main ':
: Undefined reference to `__check_region '
/tmp/ccqsb5EC.o (. Text+0x58) : In function `main ':
: Undefined reference to `ioport_resource '
/tmp/ccqsb5EC.o (. Text+0x5d) : In function `main ':
: Undefined reference to `__request_region '
Collect2 : ld returned 1 exit status
This is how it all about? That is not to #include "linux/ioport.h>; the first document? |
