plain binary restrictions?

[fdig]

Hi!

Where is the difference between plain binary and eg elf binary?
Do i have any restrictions using only plain binary? Is plain binary more portable but without any bad restrictions?

which could be reason don't using eg. elf but plain binary instead?

thanks

elf is a portable object and binary format for linux and similar OSes.

MASM32 produces Windows 32-bit PE files using coff object files (omf object files are also possible).

So you can say plain binaries are right thing to make same executable running on different platforms?
i tried linking plain binary (

Code Select Expand

$file binary : MS-DOS executable (COM))
under linux with ld, but it says "file format not recognized".
so far i am searching for good explain of differences between plain binary and elf binary / win32 binary yet.
i can't imagine if "plain binary" is binary format such ELF, COM or some art of compiling "layer".

fdig,

PE and ELF are just different object module formats. Various flavours of unix use different executable file formats and don't natively run msdos or windows files unless they have an additional layer that will recognise it. I have seen dos files run on linux and there is a wine emulator that is supposed to be getting better but they are finally diferent OS versions without much similarity so you cannot expect files from one to work on another unles there is some form of emulation software available on the target box that will run it.

Have a look at this blog entry on The Old New Thing. He describes some of the base differences between executable binaries. :U

Mybe only the emulators are

right thing to make same executable running on different platforms

Or compile twice your program /for 2 different platforms/ .

Ok, i got it.
It's easiely - that's because of it's name - clear asm. No part of ELF / PE object file container (and surely not linked).
