I am using OpenSUSE 11.2.
When I use “# rpmbuild -ba xxxx.spec” to create rpm packages of xxxx, the operation is successful but no debuginfo package is generated.
Anybody can tell me why?
Is there any solution or suggestion to this problem?

I mean how to generate debuginfo rpm package by rpmbuild.
Should I use any options, modify any configuration items or specify anything in the spec file?
