Cool stuff. Though I haven't actually run it yet (nor built atop DOS proper).
Just a few tips:
1). You don't need a separate ls.lnk file at all, even under DOS.
For DOS, you can use "CC = *wcc" (notice the asterisk, aka star) for
working with "long" cmdlines. In this case, you would use "*wlink". (I
haven't personally tested this particular fix in native DOS yet, but
I've successfully done it for other projects.) See section 10.39 in
tools.pdf.
So the relevant makefile lines would now be:
ls.exe : $(OBJS)
*wlink name ls.exe format dos debug all op map file $(OBJS: =,)
(You linked objects in different order in ls.lnk, but when I adjusted
the makefile to use the same order, the resultant binary was the exact
same as yours, built here on Win7 64-bit. And yes, you need "format
dos" else it seems to think it's a Win16 .EXE, ugh.).
2). The other obvious improvement is this:
clean: .SYMBOLIC
@rm -f *.obj ls.exe *.map
I take it that you didn't know that Wmake has its own "rm" built-in?
So no need to use multiple "del"s here. (tools.pdf also mentions that
Wmake intercepts "set" and "for".)
