1)
object by fasm,
FORMAT COFF
PUBLIC XYZ
XYZ = 34

object by masm
EXTRN XYZ:ABS

=> Alink with 2 object files is OK.


But
2)
object by fasm,
FORMAT COFF
EXTRN XYZ

mov eax, XYZ


object by masm
PUBLIC XYZ
XYZ = 34

=> Alink with 2 object files is error.
Alink says undefined seg.

You know XYZ is not a variable. It's absolute constant.

FASM doesn't work for ABS directive. (Absolute constant)

How can fasm work for external constants?

I tried with LINK and POLINK and they both have no problem linking such objects. perhaps ALINK is vulnerable for some specific layout of fasm-generated COFF objects? I have to look into it.

Thank you for your kind help.

But unfortunately I need a linker for DOS.

Alink is the only DOS linker to support both OMF and COFF.

I think polink is for windows.


Would you have any schedule for support OMF format in FASM?
(i.e FORMAT OMF)

Thanks anyway.

Maybe you could try with some COFF-only DOS linker (like ld) and OMF2COFF?

I personally dislike the OMF format, in favor of formats that are more "modern" in design (like ELF and COFF), that's why I never started implementing it into fasm. The alternative would some good COFF2OMF tool.
