A wish:

I'd like to do the following:

1. I put some asm code (ASCII) somewhere in memory
[1.2 I reserve some other mem for my beloved (kochany) fasm to put its data there]

2. I call fasm (somehow) to take a look at the code (-> 1.) and assemble it into opcodes

3. fasm tells me, if it is okay, occasionally puts its binary output somewhere (into -> 1.2 maybe)

Or in short:
I'd like to have the option of a binary output - but without using files. Just mem.

Hmmm...I scanned all docs, couldn't find something like that, so I thought, it is not possible yet - talking about 'Windows', sorry....

What do you think of this "my wish"?

It is possible if you do it,else wait for a long time.
I did it in 'octa os' but i'm not a windows programmer ,and Tomasz seems to be very busy these days.

search board for "FASM DLL" or something like that. There was DLL with FASM somewhere recently

Thanks vid, I guess you had in mind:
http://board.flatassembler.net/topic.php?t=2917

Well, as it looks to me, as if the in-memory assembling feature still awaits to be manufactured... Wink

As a beginner I think it will take some time, until I found out how to do it right Smile

i think there was already some DLL version done. But i am not sure, and i am not even sure if it was assembling in memory or from file.

In-memory assembling might be a problem - what to do when you encounter "include"? To make such version, i would suggest to take FASM sources, include them into your project, and rewrite file reading / writing routines so that they read/write memory.

Yeah, that's what is left to be done...
I just thought, I could get along without understanding the source code of fasm Wink

Now, its time for digging into.

Thanks, vid. You did motivate me.

Regarding include:
I think of either the usual file-include by name, or "inventing" a new mem-include with some form of mem address supply (shared mem) or stream-include with some form of address - why not an URL?

We will see...

depends on what you need. You can even completely disable "include" (and "file"), and make things easier.

vid, you remembered correctly. The DLL version of fasm was posted here:

I found the fasm.dll last week sometime and started to write a wrapper for it immediatly so i could intergrate assembly language into euphoria language ( I use it alot ) wich doe's not support asm syntax. The wrapper was wrote for the euphoria programming language but if anyone would like to port it or use pieces of it go ahead...

The latest version can be found here: http://www.rapideuphoria.com/fasmwrapper.zip

Would it be easy enough to port the fasm.dll source to linux *.so format?
What steps would i need to take?
I'm definatly not a linux guru...

no, it would need very big rewrite Sad

bummer, my fasm wrapper is cross platform, but needs a fasm.so for linux, oh well...

<OT> just a note for anyone interested in useing my fasm.dll wrapper for euphoria in C. useing the E2C translator shipped with euphoria, my wrapper can be translated to watcom, borland, lcc or djgpp

Hayden: why don't you link it statically? Code has only 64KB, not much these days

Thanks for the idea, that would probably work, but the problem is with linking it to euphoria, wich is an interpreted language. although I could probably to it without too much ado..., i'll look into it.

I would need to create a hybrid source wrapper, ie;

I would need to supply euphoria's cross platform routines, mixed in with modified pieces of flat assembler dll source...
