Re: Calling a C++ binary from Perl

Thanks for the suggestions, everyone! I ended up viewing the contents of all the files in the directory that appeared to be config files and noticed there was a reference to /tmp in there. I checked /tmp and found a file belonging to the c++ application that needed to be a+w but wasn't... So it was permissions after all!

So your program requires a file in `/tmp` which all local users can write to? Ouch - that sounds like sooner or later somebody is going to trash it, or remove it, and you'll be in trouble. It might be worth seeing if you can set $ENV{'TMP'} to read the file from another directory instead.., Steve --- <a href="http://www.steve.org.uk/">steve.org.uk</a> : <a href="http://www.debian-administration.org/">Debian System Administration</a>	[reply]

Don't do that. Chances are that the file was created while you were testing your app with your account, but if the app is supposed to be executed only by the apache/nobody/whatever CGI user just change the file owner leaving the permissions as they are were before (you probably can afford pretty the same result simply removing the file and letting the application re-create it from scratch). Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))') Don't fool yourself.	[reply]
