[Tutor] launching and monitor from make

[Ertl, John]

Ewald,

That easy...If you know.  Thanks for the example and the help.  Now lets see
if I can modify the make file without upsetting the make god.

Thanks again.

I think your Python-Script is an executeable "Shell"-Script with
"#!/usr/bin/env python ... "
So you can just insert your script in the makefile

When the exit-Code of the script is 0, than make assumes that everything is
ok,
otherwise an error occured.


Here's a short example with "ls"

Here the mkfile want's to list the file "hugo" which does not exist

mkfile:
all:
	ls -l hugo
--------------
#gmake -f mkfile
ls -l hugo
hugo: Datei oder Verzeichnis nicht gefunden
gmake: *** [all] Error 2



Here the mkfile itself is listed with ls
mkfile:
all:
	ls -l mkfile
----------
#gmake -f mkfile
ls -l mkfile
-rw-rw-r--   1 ewer     entw          19 Okt 12 16:35 mkfile
