[opensuse-programming] Where to save "global" data files from application

by opensuse＠sky-bizz.com

Hello [at first: i am not new to developing software, but i am slightly new to developing linux-software :)] i'm just developing an command line tool for linux (c++), which has to save its data into a single file in the filesystem, undependently from running user. its handling is best described like or compared with "updatedb". there is only one data-file for all users. in which folder should i create the application's data-file, and whats about the needed rights on it? can this application "ask" for getting needed privileges like on windows? is there a special folder intended for handling such things? if yes, what folder? kind regards for any help hagen --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org

[opensuse-programming] make - simple vs. recursive variables

by Per Jessen

All, I think I'm seeing something odd in 'make': Makefile#1: ALLDOMAIN:=alldomains.list #ALLDOMAIN:=$(shell mktemp alldomain.XXXXXX) .PHONY: $(ALLDOMAIN) .SILENT: $(ALLDOMAIN) $(ALLDOMAIN): <commands to produce the file> >$@ include $(ALLDOMAIN) The $(ALLDOMAIN) file defines a target named 'alldomains', so I should now be able to do "make -f Makefile#1 alldomains". Except - when ALLDOMAIN is a simple variable (assigned with :=) it doesn't work. The 'alldomains' target can not be found. When ALLDOMAIN is a recursive variable it works fine .... I need ALLDOMAIN to be set up only once - see the commented out line that gives me a temp file. What am I doing wrong here? /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org

[opensuse-programming] pcre match_limit

by Per Jessen

All, I'm using PCRE (the C-library) to extract base64 encoded attachments from emails. Needless to say, such attachments can get pretty big. I've been getting segfaults, so I have been playing with the match_limit (as far as I can tell, it's not a stacksize problem). However, according to the pcreapi man page, the default match_limit is 10million - where as I'm having to keep it at 15000 or thereabouts. I'm right now trying to find the optimal level. Can anyone explain why I would have to set it so low? /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-programming+help(a)opensuse.org
