[Tekmovanje] Narediti najkrajši exe alla "Pozdravljeni" v winxp sistemih

StratOS :: 21. jun 2006, 21:54

Evo končno nekaj pametnega :

Tekmovanje narediti najkrajši exe skompiliran program, ki izpiše "Pozdravljeni" v winxp sistemih v različnih programskih jezikih (VB,C,asm,TP ...)

Mislim, da nekaj takega še ni bilo, na Vas pa je, da to tudi naredite.

Zraven še prosim pripišite s čim in kako ste omenjen program naredili/skompilirali

Veliko veselja

Konzola ali grafično?

Ni važno, glavno, da je najkrajši :D

sverde21 :: 21. jun 2006, 22:12

če vela PHP:

<?="Pozdravljeni"?>

Samo ne vem, če je tole primern, ker ni standalone...

EDIT: Aja exe :) podčrtaj tist, sm spregledu

P.S.: Grafični je logično daljši...

<?php echo `w`; ?>

Evo npr. enega na hitro v VB6, dodatno skompresiran z upx.

Evo, 4.608 bytes

Predvidevam, da se bo našel kak asm tzar, in sklal skupaj program, ki bo imel več bajtov za string kot pa za kodo

lahko naredimo tekmovanje za vsak programski jezik

"It works better if you plug it in."
"The one who is digging the hole for the other to fall in is allready in it."

smetko :: 21. jun 2006, 23:02

ena od možnosti.
Skreiraš bat datoteko v katero vneseš "ECHO Pozdravljeni".
Iz mesta http://www.computerhope.com/dutil.htm vzameš program bat2exe in s tem programom pretvoriš bat program v .exe (sicer dobiš .com vendarga lahko preimenuješ v .exe).
Jaz sem tako dobil program velikosti 109 Baytov.

C, v windows konzoli: 2048 bytov. ;)

#include <windows.h>
#include <stdio.h>
int main(void) 
{
    printf ("Pozdravljeni!\n");
    return 0;
}

prevedeno z eno starejšo verzijo gcc (mingw):

$ gcc -Wall -Os -DDEBUG=0 -c hello.c
$ gcc -o hello.exe hello.o -mconsole -s -Wl,--stack,1048576 -nostdlib -nostartfiles -lctiny -lkernel32 -luser32 -lshell32 -ladvapi32
$ strip hello.exe

še preverim, da res nima kakšnih čudnih odvisnosti (msvcrt, msys, cygwin). Evo, tale exe dela na vseh win9x, winnt sistemih:

$ depends hello.exe
hello.exe: GDI32.dll
hello.exe: USER32.dll
hello.exe: ntdll.dll
hello.exe: KERNEL32.dll
hello.exe: hello.exe

veteran :: 21. jun 2006, 23:11

Moj rezultat: programček zavzame 31 B, od tega zavzame 12 B beseda "Pozdravljeni", ki se izpiše.

Kam submitam programček? ;)

Ej, saj piše, mal višje. ;) BTW, z gcc lahko narediš tudi win program iste velikosti (2048). Manj pa kvečjemu z M$ linkerjem (ker zna združit sekcije v PE).

#include <windows.h>

int WinMainCRTStartup (void)
{
    MessageBox (NULL, "Pozdravljeni!", "", MB_OK);
    ExitProcess (0);
}

Ne bom smetil z uuencode še enkrat (če ima kdo posebno željo, lahko dobi v ZS;). Predlagam pa, da bi forumu že končno dodali en knof PRILEPI DATOTEKO, ker je skrajno nadležno, da moraš prav vsako slikco ali datoteko najprej nekam odložit.

MSWin XP v konzoli nekako emulirajo MSDOS ne? Torej bi šlo

;tukaj je treba namutiti asemblerske direktive

MOV AX, CS; MSDOS klic #9 uporablja DS segment, naši podatki so očitno takoj za kodo...
MOV DS,AX
MOV AH,9
MOV DX, OFFSET str
INT 21h
XOR AX,AX ; MSDOS exit klic

xchg    eax,ebx
add     eax, dword 4
mov     ecx,msg

Ampak dobro no, kaj pa če tvoj grozni add:
xchg eax,ebx
add eax, dword 4
nadomestiš s temle
mov bx, ax
shl ax,2
? Oz. lahko še nadomestiš z osem bitnimi registri samo dvomim da bo krajše.

Drugače pa zanimivo, da so vsi registri kar na 0 na začetku 8-O

Gundolf,

119 bytov, z Hello World stringom, ki je v data segmentu in ni v ELF headarju zakamufliran. Torej en byte vec, kot jaz.

Ja, nekaj stvari se da se nadomestiti z osem bitnimi registri, samo ni nic krajse.

Vsi registri na nuli? Saj ne vem, da so... ;>

.com je bolj tako tako. To pravzaprav sploh preveden program ni. ;)

? .COM je star MSDOS exec format za 8086, omejen na 64 KB (podatki in koda). Recimo večina MSDOS C prevajalnikov iz časov, ko je bilo to aktualno ga je podpirala v obliki "tiny" modela - itak, da je lahko preveden! Je pa problematičen, ker je v resnici to samo binarna slika programa na disku. Ni headerja in zato tudi ni nobene možnosti, da bi se ga naložilo kam drugam kot na določen dogovorjen naslov v pomnilniku.
