Thanks for any help.
I downlloaded the FASM assembler and ran it.
Have no idea where it is on my Puter.
Have no idea how to get an executable module.
Where the question marks are I don't understand the instruction.
Am running Ubuntu.
Really I need a book like FASM for Dummies.

; 1st fasm program 2-17-09 (put the letter A to the screen)

; Compile with:
; fasm fasmjps.asm A1stprog.o

format ELF executable
entry start

segment readable executable ; ???????

start:
mov eax,4 ; sys-write
mov ebx,1 ; unsigned int ??????
mov ecx,msg ; item to screen
mov edx,msg_size ; size of item
int 0x80 ; call the interrupt

mov eax,1 ; sys-exit
xor ebx,ebx ; unsigned int ??????
int 0x80

segment readable writeable ; ???????

msg db 'A',0xA
msg_size = $-msg

  • segment is just something to tell the OS what type of page permissions to set for the page.
  • unsigned int is a way of interpreting the contents of the register. Unsigned means no negative values. 32 bit can store up to ~4 billion.

Thought I had FASM uncompressed but I didn't. So that's fixed now.
It's in places/home/jack/fasm. Whether this is correct or not I have no idea.
Any way I can't compile my little program.
I keep on seeing references to a command line. Where the devil is that?????
Is that the only way to compile the program?? Something that should takes minutes to figure
out is now taking many hours. Ridiculous.

The fasm IDE is only for Windows. In Linux you will have to use the command line version.

Thank you Revolution for responding.
As far as I can tell I am using the correct version of FASM
Fasm Assemnbler 1.67.32 for Linux

Still can't compile a simple program.
What is the "Command Line"?
I guess It looks like I'll have to find a more compatible Assembler in Linux.
Things just DON'T need to be this evasive.

It is a *nix thing. Many a program will need the command prompt (the shell) to run things.

Command line is:
Code:
fasm fasmjps.asm    
or (if fasm is not added to the PATH environment variable)
Code:
/home/jack/fasm/fasm fasmjps.asm    
Since you defined your program to be an ELF executable, thus fasm won't generate object file A1stprog.o but only the bare executable that will have the name fasmjps.

Really? I thought all OSs had them. Does windows even have a way to ping without using a command line?

Sure, but only the *nix OSes seem to rely on the user knowing how to use it.

Really? I didn't know it was the OS' fault that the creators of a third party program decided not to make a GUI for it.

Several useful programs that are built into windows don't have GUIs.


So aren't command lines more a windows thing then a *nix thing?



Ew wtf got this when I tried to post

I was not trying to blame the OS, but the fasm executable for *nix requires the user to know the command line. Just a statement of fact.

Oh. Sorry. I thought when you said "It is a *nix thing" you meant the command line. I'll try to read more carefully before replying next time.

Both DOS and Windows have working IDEs, *nix does not. That is all I meant.

None of them got fasm. It would be great one could be adapted for fasm, then users like phenix would find it easier to get started.

What needs to be changed in *nix to let fasm have a GUI?

Nothing to change in the OS, just to get an IDE for fasm working.

Oh. So it's nothing to do with *nix? We just need to find who maintains fasm and ask him to make a GUI version?

That's what I thought, but then it wouldn't be a *nix thing..
