Problem:

Undefined Symbols messages are telling you that your code contains references to entry points which the generator is not able to resolve at link time. As the generator will create direct references to these entry points they need to be resolved at link time.

Resolution:

The options are:

1. Link in the code which contains the missing entry points into the executable.

2. Tell cob that the entry points will be dynamically loaded at run-time by adding:

"-d entrypointname" option to the cob line.

3. Let cob work out they need to be dynamically loaded at run-time by adding "-U" to the cob line.
