我有rfact.s和rfactmain.c如何鏈接兩個目標文件
rfact.s：
.text
.p2align 4
.global rfact
.type rfact, @function
rfact:
pushl %ebp
movl %esp, %ebp
pushl %ebx
subl $4, %esp
movl 8(%ebp), %ebx
movl $1, %eax
cmpl $1, %ebx
jle .L53
leal -1(%ebx), %eax
movl %eax, (%esp)
call rfact
imull %ebx, %eax
.L53:
addl $4, %esp
popl %ebx
popl %ebp
ret
rfactmain.c：
int main(){
int x = rfact(4);
return 0;
}
我是一個64位系統。因此，首先我做
gcc -m32 -c rfact.s
gcc -m32 -c rfactmain.c
同時獲得目標文件，然後我試圖把它們像這樣
gcc -m32 -o rf rfact.o rfactmain.o
聯繫在一起，但我得到一個錯誤
gcc -m32 -o rf rfact.o rfactmain.o
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory

/usr/bin/ld: cannot find -lgcc_s
/usr/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status
如果我刪除-m32我得到錯誤（這是預期的，因爲兩個目標文件都是32位）
gcc -o rf rfact.o rfactmain.o
/usr/bin/ld: i386 architecture of input file `rfact.o' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `rfactmain.o' is incompatible with i386:x86-64 output
