Imposible with fasm, you need a external tool (a linker). Create an object file (COFF, MSCOFF and ELF are supported) of your program and later use a linker.

or make an equate file to support your obj file.
and include it in your source. need to load the object when program starts.

NO, FASM doesn't suport OMF objects, this has been discussed many times, several people complained, Tomasz didn't make any statement on this issue Sad

YES, you need a linker for OBJ's, like VALX.

For 32-bit code you can try come "COFF2OMF" tool (untested, at your risk).

You probably could brew an OBJ manually, as one can do with MZ, LE and PE.

NASM and LZASM do support OMF OBJ.

Why use OMF object files when there's COFF? Just find a decent linker Smile

I explained this in a few other places, too.

YES, long time ago. I was somewhat wrong Sad

NO. It's not about finding a D.L. or L.D. Laughing - it's about (OK, not very up to date) 16-bit (there is no COFF-16), and using FASM with compilers and linkers using OMF (VALX), and existing OMF stuff.

I'l add a FAQ ASAP Idea

DOS386: sure, if somebody is doing 16-bit code, they won't be using COFF. (But why write big 16-bit programs these days?).

Most people asking about OMF/COFF, however, tend to be using 32-bit borland tools... and there, the solution is to move to a better toolset.

Why not? 16 MB should be enough for anyon... oh wait, never mind. Laughing


  • legacy code/libs that you want to use
  • still got 286s lying around (not me, sadly, heh)
  • working with embedded systems
  • fun (maybe someone likes the challenge)


Wink

P.S. Try Agner's OBJCONV (via HX if need to run in pure DOS).
