In general, you want error messages to go to sys.stderr and you want to return an error code other than zero. Send messages to stderr: print >>sys.stderr, message Return error code raise SystemExit(1) At this point, make will respond to errors correctly. You can use make's -k option to ignore them, but the error messages still go the same place as other programs.

Re: [Tutor] launching and monitor from make
Alan, Thanks, just as you and Ewald said it works great. Almost too easy...I have this feeling something will turn around a bite me once it goes to ops.

You can also exit with an error code using sys.exit(). make should detect the non standard error code because it uses standard shell processing..

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 HTH Ewald Ertl ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
