레뎃6.2설치된 스팍머쉰 프린트포트에 LED꽃아서 간단하게
제어해볼라고 하는데요..
#include <stdio.h>
#include <unistd.h>
#include <sys/io.h>
#include <stdlib.h>
#define PORT 0x378
int main()
{
while(1){
ioperm(PORT,3,1);
outb(0x09,PORT);
sleep(1);
outb(0x06,PORT);
sleep(1);
}
}
[root@node00 /root]# gcc check.c -o check
/usr/include/asm-sparc/io.h: In function `mapioaddr':
In file included from /usr/include/sys/io.h:6,

위와같은 에러가 나는데 에러나는 부분을 보니까
extern __inline__ void mapioaddr(unsigned long physaddr, unsigned long virt_addr,
int bus, int rdonly)
{
switch(sparc_cpu_model) {
case sun4c:
case sun4:
sun4c_mapioaddr(physaddr, virt_addr, bus, rdonly);
break;
case sun4m:
case sun4d:
case sun4e:
srmmu_mapioaddr(physaddr, virt_addr, bus, rdonly);
break;
default:
printk("mapioaddr: Trying to map IO space for unsupported machine.\n");
printk("mapioaddr: sparc_cpu_model = %d\n", sparc_cpu_model);
printk("mapioaddr: Halting...\n");
halt();
};
return;
}
위부분에서 에러가 나는것 같은데
어떻게 수정을 해주어야 될지 잘모르겠네요.. ^^;;

앗 글구요.. 스팍에서도 프린트포트 넘버가 378번 맞나요? ^^;
컴파일러 버젼은 gcc version 2.95.3 20010315 (release) 입니다
