Hello,
I would like to make zeos step-into the field setter, how should I do
it?

That is, debug field1.asString := '';

Thank you.

In order to debug zeos (or any package): Open that package, from the
packages toolbar choose options, go to debugging, and enable debug
info (dwarf-3 / unless you use gdb, then it is dwarf-2+sets).

After that the debugger should step in.

It works.
Other problem, however, it fails step into with a standard tfield
(i.e., that of the standard LCL "fields.inc"). I have compiled Lazarus
in Debug IDE but it does not work F7 and breakpoint. Should I do
something else?

Resolved.
Now what I do is try to find the bug I found zeos 8 with the
calculated fields (I try). For those interested in trying to solve it
I also wrote an example that reports the problem.

You mean TField in unit "DB" in folder fcl-db? => That is part of fpc.
You need to rebuild fpc, using the make files. Or using fpcupdeluxe.
