assembly x8086 undefined reference to 'pause'
0
I'm trying to assemble a simple file and then i want to stop the video to see what I've done. The code is:
*.GLOBAL _main
.DATA
stringa: .ASCIZ "Questa e' la stringaaa"
lettera: .BYTE 'e'
conteggio: .BYTE 0x00
.TEXT
_main: NOP
MOV $0x00, %CL
LEA stringa, %ESI
MOV lettera, %AL
comp: CMPB $0x00, (%ESI)
JE fine
CMP (%ESI), %AL
JNE poi
INC %CL
poi: INC %ESI
JMP comp
fine: MOV %CL, conteggio
CALL pause
RET*
when I try to assemble in the cmd using the command:
gcc -o file file.s
I get the state:
C:UsersUser nameAppDataLocalTempccegNf7o.o:fake:(.text+0x23):
undefined reference to `pause'
collect2.exe: error: ld returned 1 exit status
It seems simple but I tried so hard and still don't succeed.

pauseis not a function you can'tcallit. Trycall getcharinstead.

Set a breakpoint on theretin a debugger, or run your program from inside an already-existing terminal window, if you can't configure a terminal to stay open after running your program.

I tried and it's the same, instead of 'pause' there's 'getchar'

Actually use_getcharas your environment apparently uses leading underscore on functions. (Also let me correct myself:pauseis a function at least per POSIX, but it's probably not what you were looking for.)
