Re: Re: External C ran from External Perl ran from CGI

I dont get this problem if I run the software locally, but it crashes with a segmentation fault if I try to run it via CGI. This seems to come up a lot. Usually, it happens because when you run it "locally", your personal user account has permission to read, write and/or execute particular files in cited directories, whereas when it runs via a web server, the web server's user account (usually "nobody") does not have the same permission. Check permissions on the various directories and files involved.

Httpd.conf runs has the user set to be "tomcat" The program ($hbplus) itself is owned by root, but has these permissions: rwxr-xr-x.

The directory into which the resulting file is created (cwd) is owned by "tomcat", and is writable. To prove that, the log file created by '>$hblog' IS created in the same directory.

However the log file is empty, so it seems like the program crashed before it even started...
