Thread: .exe extension on Windows

.exe extension on Windows

From
Peter Eisentraut
Date:
Can somebody confirm how the executable extensions behave on
Windows/Cygwin? It seems that the following is true:

cc -o foo ...

creates a file `foo.exe'.

cc -o foo.exe ...

also creates a file `foo.exe'. Is that correct?

It also seems that the make targets need to be written like

pg_passwd$(X):

rather than

pg_passwd:

because otherwise you're not really updating the target of the rule.

 I agreed this.

Hmm,I see the following in my environment.

bash-2.02$ ls
CVS          Makefile     pg_passwd.c  pg_passwd.o
bash-2.02$ make pg_passwd
gcc -o pg_passwd
pg_passwd.o -lcrypt -lm -lreadline -ltermcap -lncurses -lcygipc
 -g
bash-2.02$ ls
CVS            Makefile       pg_passwd.c    pg_passwd.exe  pg_passwd.o
bash-2.02$ make pg_passwd
make: `pg_passwd' is up to date.

Regards.

Seems make is smarter than it wants to admit. Then that would not sit well
with the changes I just made (which would require you to do `make
pg_passwd.exe', unless make is *that* smart). Gotta investigate this in
the GNU make manuals. Thanks.
