I want to ensure that every command was successfully executed. The return values will be ignored if the commands are concatenated by the metacharacter ";". I prefer to use "AND lists" here. > So you either a .config file or the config directory. I would expect that both will be generated in my output directory by a command like "make silentoldconfig". Why is the cleanliness check additionally performed on my source directory? Should it really matter if I want to concentrate on "objtree"? > If you now say this is a SUSE specific problem then I suggest asking SUSE for help. I don't want to say that. I indicated a bit about my runtime environment. Is it more likely that the Makefile will need an update? Regards, Markus
