All these undefined references ("zi" => ".") seem to be within your own
package "CHD", but guessing what goes wrong exactly is a bit hard without
further information. A complete log of what you are doing might help, a
tar file including your sources would be even better (when building is as
simple as "make" or the like). This is a general hint for people reporting
non-trivial problems: Whenever possible, package up everything necessary for
reproducing the problem in a way that a plain "make" suffices, and attach it
to your problem report. Remember: This is a "lazy" mailing list... :-)
