How do I make an EXE? (question 2)

[Special Link 2]

I have a file called 'hello.txt' with Assembly code, but I do not even know how to begin to convert to exe,



Someone please can explain step by step how do I convert to exe?   Note: please a very detailed explanation because I am too inexperienced.


My operating system is Windows 7 in Portuguese

Depends on the contents of your "hello.txt" file. Usually, you will use Nasm to assemble "hello.txt" to "hello.obj" and then use a linker to create "hello.exe" from "hello.obj".

Since Nasm will produce several types of linkable object file, we need to tell Nasm which kind we want. Probably:

Code: [Select]

nasm -f win32 hello.txt
or

Code: [Select]

nasm -f win64 hello.txt
or possibly...

Code: [Select]

nasm -f obj hello.txt
(in this case you may want to find a different source file - this is "obsolete", but should still work)

Then you'll need a linker. Jeremy Gordon's "golink" is probably your best bet unless you have another you prefer:

If that doesn't fall into place, you may need to show us "hello.txt".

What was question 1?

so far did not understand was nothing.

1) only cmd.exe used only three times in my life, this is the fourth

2) I do not know if what I'm writing in cmd.exe is right or wrong, I do not know what the order of writing


3) this code that you insert when I said in cmd.exe?

 the file hello.txt is in E: \ or whatever address is E: \ hello.txt

the nasm.exe is in C: \ Users \ Speciallink \ nasm-2:11:08 ie the address is C: \ Users \ Speciallink \ nasm-2.11.08 \ nasm.exe


when I open cmd.exe is already written C: \ Users \ Speciallink \
and then I write what I want and looks like this:



C: \ Users \ Speciallink> nasm-2.11.08 \ nasm.exe nasm -f win32 hello.txt -IE: \ hello.txt

then the cmd.exe says:


nasm: error: more than one imput file specied

type 'nasm -h' for help

C: \ Users \ Speciallink>



hello.txt the content is this:

• section .data
• msg     db      'Como programar em Assembly - Curso Assembly Progressivo', 0AH
• len     equ     $-msg
• section .text
• global  _start
• _start: mov     edx, len
•         mov     ecx, msg
•         mov     ebx, 1
•         mov     eax, 4
•         int     80h
•         mov     ebx, 0
•         mov     eax, 1
•         int     80h

Well... the last time I ran Windows, Win98 was current, so I'm not going to be able to help you much with OS questions! I can tell you for sure you'll need some different source code - what you've got is for Linux. The "int 80h" is the tipoff. Code for Windows would probably say "extern" - maybe "extern ExitProcess" would be good to look for?

The error "more than one input file specified" may be just because you said both "nasm.exe" and "nasm", but that's just a guess. You'll need different source code anyway... or install Linux.

Can some Windows user get Special Link 2 on the right track? It'll go along easier once you get started - honest!

Best,
Frank

Edit: This might be someplace to start. At least it's got some valid Windows code...

This guy wants to make an Windows executable but assembly file content shows "int 80h" linux kernel system calls. Confused  Seems like he is using wrong file for windows platform.
