OS를 컴파일하기 위해 make를 사용하는 동안 make가 이해할 수없는 이상한 오류가 발생했습니다. 메이크업에서충돌하는 유형 및 이전 함수 선언?
: 문제
source/paging.c:179:6: error: conflicting types for ‘page_fault’
headers/paging.h:68:6: note: previous declaration of ‘page_fault’ was here
make: *** [obj/paging.o] Error 1
기능 (들)을 따르는 것입니다. 나는 paging.c의 전체 파일을 포함하지 않았기 때문에 매우 큰데 paging.h tbh도 마찬가지지만 헤더 파일을보고 싶으면 나머지는 게시 할 것이다.
paging.c :
....
....
void page_fault(registers_t regs)
{
// A page fault has occurred.
// The faulting address is stored in the CR2 register.
u32int faulting_address;
asm volatile("mov %%cr2, %0" : "=r" (faulting_address));
// The error code gives us details of what happened.
int present = !(regs.err_code & 0x1); // Page not present
int rw = regs.err_code & 0x2; // Write operation?
int us = regs.err_code & 0x4; // Processor was in user-mode?
int reserved = regs.err_code & 0x8; // Overwritten CPU-reserved bits of page entry?
int id = regs.err_code & 0x10; // Caused by an instruction fetch?
// Output an error message.
monitor_write("Page fault! (");
if (present) {monitor_write("present ");}
if (rw) {monitor_write("read-only ");}
if (us) {monitor_write("user-mode ");}
if (reserved) {monitor_write("reserved ");}
monitor_write(") at 0x");
monitor_write_hex(faulting_address);
monitor_write("\n");
PANIC("Page fault");
}
paging.h :
....
....
void page_fault(registers_t *regs);
....
....
참고 :이 튜토리얼이다 (그래서 작동해야하지만, 내가 제공 문제에왔다 하나의 함수의 철자가 정확하지 않은 곳의 소스 코드).
make가 불평하는 이유는 무엇입니까?
감사합니다.

이는 링커 오류이므로 일부 라이브러리 또는 개체 파일이 명령 줄에서 누락되었습니다. 편집 자체가 잘 완료된 것 같습니다. –
