If you've installed OpenWatcom using "installation disks," I don't
know what that means. Did you download the compiler from the
OpenWatcom website and install from that? For myself, I'm using the
OpenWatcom as we provide it in the distribution.
I'm not sure why "wcc prova.c" then "wcl prova.obj" works, but "wcl -c
prova.c" then "wcl prova.obj" does not. The "-c" option means "compile
only."
This is very odd. I wonder if there's something in the DOS
environment? Probably not, but worth checking. (When I compile on
FreeDOS, I only set the environment variables that I need. I run
OWSETUP.BAT to set up my OpenWatcom environment, and I compile with
that.)
At least, something is happening in the object file, or at least in
the link stage.
Here's my test. I started by creating a new test file:
D:\TEMP>edlin prova.c
prova.c: New file.
*i
: #include <stdio.h>
:
: int main()
: {
: puts("Hello world");
: return 0;
: }
: .
*w
prova.c: 7 lines written
*q
Really quit (Y/N)? y
In my OWSETUP, I have this line to not have the DOS extender print anything:
set DOS4G=quiet
Then I compile like you did:
D:\TEMP>wcl -c prova.c
