Re: How do I check if a directory exists?

[Jimmy DeWitt]

Tristan,
      Thanks.

      This accomplishes some of what we need.  If "my_dir" exists, make
treats the
"my_dir"/Makfile dependency as an actual file within a subdirectory, and a
"touch" of
/my_dir/Makfile will force a recompile.

      If my_dir doesn't exist "my_dir/Makefile" is treated as a target.
Since there
 no rule exists for that target, make crashes.

      We would like make to stop if there are no other targets to build, or
go to the next target
if running "make.all"

Would this suite your purpose ?


target: my_dir/Makefile
             $(MAKE) -C my_dir
