Have you noticed that without fixups directory fasm says "code cannot be generated"? The "weird" part is that with the other possible formats there are no complaints if "format X" is the only line in the source.

I've never tried to assemble a file with only a "format ..." line. I didn't really see the point. But nevertheless, a bug it would seem.

I don't know but this behavior is present on FASM 1.64 also so if it is a bug then it is an ancient one (but not as ancient as the [reg*0] bug Razz)

It can be instructive to see the minimal (not necessarily working) structure of the target binary for educational purposes, but in average quite useless, yes.

Format pe native ?    


I tried but it gives no results, no ".sys" file.

Sure it does.
Code:
format pe native
nop    
Generates a .sys file on my system. What version of fasm are you using?

BTW: LocoDelAssembly, just putting a single nop (like my code above) is enough to get it to assemble.

I use Fasm with Radasm.
Radasm ask me if I want to build "Win32 app" or "dll" ... I chose "win32 app" ... but there must be a problem on this side there. With "win32 app" (radasm) and "native format pe" ... I have a ".exe" file.
(Fasm 1.67.29 for windows)

I suggest you contact the Radasm authors to fix the problem. Although, in the meantime, a simple renaming would probably do the trick nicely, since fasm will still generate a .sys file but Radasm just decides to name it .exe
