Hi..

I just want to know if there is a program that i can download to convert C language to assembly in WINDOWS XP

..

I got linux(redhat v9) but i dont know why there is a problem with GCC compiler which gives me (when i enter any thing with gcc at the begning) no such command, also when i try to use the debuger (gdb).

..

also if there is a good debuger(for windows xp) that i can use to debug .o files .It will be helpfull, also if there is something that can convert .o file to assembly or C language.

..

please help me , i got an assignment to do (its realy easy but i cant do it becuase its in .o , what we take in class is to use gdb with it but i cant with my PC :( )

..

Thanks for reading
bye..

GCC can do it. just type: gcc -S myfile.c any compiler can do this, just read the documentation

I downloaded GCC in windows but there is something that i have to change in AUTOEXEC.bat accualy i didnt find this file in my PC i found AUTOEXEC.NT

thats why gcc compiler isnt working with my windows :(

thanks for responding :)

what you want is a dissasembler. try win32dasm . iirc it's not free, but i found some warez googlin around awhile back

Many, maybe most, compilers have an option for emitting listing files, which are assembly language. I downloaded a disassembler called disasm, but I don't remember where from. It appears to work, although I haven't used it except to disassemble its own .exe file.

you can use the free debug.exe that is distributed with windows operating system. it will show the assembly code of any executable, and the binary/hex/ascii representation of any file.

kind of cryptic -- but it works.

mmm iam trying to find 1
i found Win32Dasm All Versions in werz site which is 100 mb size
should i download it or find better 1

[BaAa3]

I downloaded win32dasm v893_1
i just conver a little C code and it gives me a realy strang codes which i didnt understand :) is there is a program that can give some thing like linux gcc compiler !


that is the C code :


#include <stdio.h>
int main ()
{
int a , int b ;
a = 6 ;
a = b ;
return 0
}

that what it gives me

LOL, man, what did you expect? Idiomatic English? That's assembler code, horribly formatted. Here's a sample of the output from the one I'm attaching. You can look at it and do what you will.

Oh..
WOW why its like this in windows, in linux its too much easyer
I dont know why my comiler wont work in linux :(

Thanks anyway u were great guys ;)

[BaAa3]

mmm

Is there a program that can convert assembly to c language

if there is please tell what is it , and if u can wjere to get it !

:)

I understand the the million monkeys that are producing Shakespeare have a copy...

It sounds like the problem you are having with your linux setup is that the path does not include the location of gcc. Try explicitly giving the full path to gcc or gdb, and see what happens.

You can also install gcc on Windows. It is included with the cygwin unix tools port (http:/www.cygwin.com/). If you download and install the full version then it should include everything you need to do your project.
