<0> hey , im trying to learn the basics of ***embly and i have a problem with compiling my project to exe file , im using a program called most and when i press compile it generates .obj file , .bak file and .txt file if anyone knows this program how do i get an .exe file with it??? or what do you suggest thank you for your time and sorry about my noob question :)
<1> You will probably need a linker, sir.
<0> this program includes a Link.exe file in its folder
<0> oh no wait
<1> If you run the object file through the linker, it will generate the exe for you.
<0> tlink.exe
<1> Usually ***emblers offer an option for executable generation.
<1> Ah yes. Turbo Linker will link executables for you :)
<0> :DD
<1> However, it working depends on your ***embly code.
<0> i will try it sec
<0> love
<1> If your code is written for and executable, then it will work. But simpler programs are usualy ***embled into .com files.
<0> i dragged the obj file on the tlink.exe and it generated an .exe file
<1> There you go :)
<1> Does it work?
<0> thank you
<1> Anytime, sir :)
<0> i will try to debug it
<0> program has no sibol table :(
<0> symbol
<1> Yes, that will probably be the debugger trying to load the debug information out of the executable.
<1> Did it run okay?
<0> mmm
<0> how do i know if it runs ok
<0> i have writen a simple project
<1> What does the project do?
<0> that adds tow numbers
<0> :D
<0> im just starting
<1> Okay, it might be better to start ***embly programming with .com files.
<0> the project acording to most have no errors
<1> Or should I say, easier :)
<0> but i wanna know why cant i debug the exe file?
<1> Because there are no symbols in it. So there is nothing to debug.
<1> Or atleast, your debugger thinks there aren't any.
<1> :)
<1> Can I see your code?
<0> sure
<0> www.pastebin.com ?
<1> Whichever is your preference :)
<0> pastebin is stuck
<0> you have another paste site link?
<1> Try www.nomorepasting.com
<0> thx
<0> URL: http://www.nomorepasting.com/paste.php?pasteID=66543
<0> i must make the debugger to work
<1> I unfortunately don't have an ***embler that will ***emble TASM code, but if you check the options on Tasm, it should generate debug information.
<0> it doesnt have any option tab
<0> or im blind
<1> Try the command line :) "tasm /h" I think.
<1> That should list the options.
<0> /zi,/zd Debug info: zi=full, zd=line numbers only
<0> that?
<1> Yeah, try with /zi.
<1> That might give your debugger something to chew on :)
<0> :D
<0> trying
<0> mmm what that command line suppose to do?
<0> it didnt generate any file or anything
<1> Add debugging information to the .obj file. So the debugger can do things like ***ociate an address in the machine-code with a line in your source.
<1> You will need to add that as an option to a normal ***emble: tasm /zi input.asm
<0> oh
<1> Something like that.
<0> i did
<0> and then link the OBJ?
<1> That's right, better to check to make sure the linker won't strip the debug information too :)
<0> still same error
<0> :/
<1> Blast.
<0> mmm
<0> look
<0> i'll paste the command i did and the result
<0> maybe u'll understand something
<0> sec
<0> URL: http://www.nomorepasting.com/paste.php?pasteID=66545
<1> Shame I don't have TASM here
<0> lol
<0> maybe i'll send u mine
<1> Give me a minute to have a dig around :)
<0> k
<0> its 800k
<0> if u want i can host it
<1> Just a moment, sir.
<0> np
<1> Aye, you'd better :)
<0> better what?
<1> I have no TASM :(
<0> shall i host it or send via irc?
<1> Probably best to host it, if that is not too much trouble :)
<0> nah
<0> you have a dump site?
<1> Not myself, no.
<0> any known one i mean
<1> Sorry, no.
<0> k i'll look
<1> Got it.
<1> Nope, not got it :
<1> :/
<1> LoL.
<0> lolz
<0> cant find anything with no registration
<1> Blast.
<1> Well, I chewed your code so MASM will compile it, but now the linker doesn't like it! LoL.
<0> omg
<1> MS linker ****s sometimes.
<1> LINK : fatal error LNK1221: a subsystem can't be inferred and must be defined
<1> Neat.
<0> i want exe file with symbol table :,(
<1> Odd that your debugger doesn't just debug the exe with no symbols...
<0> what does it mean?
<1> The symbol table tells the debugger what element in, say the data segment, ties to what symbol in your source code.
<0> yea
<0> maybe my debugger just ****s
<1> Well, I've linked it now :/
<1> And it crashes spectacularily :)
<0> lol
<0> hymm
<0> what does it mean
<0> :P
<1> Just a moment.
<1> Btw, about your code...
<1> Where did you get it from?
<0> from a book
<1> Why sub bx, bx; mov ax, [bx]
<1> When bx isn't initialised with any value?
<0> maybe just in case
<0> :p
<1> Eh?
<0> it cant have any grabage on it?
<0> gurbage
<1> LoL.
<1> It seems that there is garbage, sir.
<0> lol
<1> And the mov ax, [bx] is trying to read from such a garbaged address.
<1> Unless I'm missing something ;)
<1> Have you checked your book to make sure the program is the same?
<0> mm
<0> yes
<0> mm
<0> [bx] should have the first 2 bytes of the data segment if im not wrong
<1> ax and ds will.
<0> should point
<0> which mean pointing to 5678
<1> Where did that number come from?
<0> from first dd 12345678H
<1> Ah, okay.
<1> AX and DS will point to the datasegment.
<0> sub bx,bx will make bx = 0
<0> and then bx will point there
<1> But bx will be zero, not ds.
