are any warnings while linking. By default, this checkbox is deselected, and the linker pro-

ceeds with generating output files even if there are warnings.

Selecting this checkbox displays any warning (as errors), regardless of the state of the

Show Warnings checkbox in the General page; see the Show Warnings section on page

70.

Treat Undefined Symbols as Fatal

When selected, this checkbox causes the linker to treat undefined external symbol warn-

ings as fatal errors. If this checkbox is selected, the linker quits generating output files and

terminates with an error message immediately if the linker cannot resolve any undefined

symbol. By default, this checkbox is selected because a completely valid executable can-

not be built when the program contains references to undefined external symbols. If this

checkbox is deselected, the linker proceeds with generating output files even if there are

undefined symbols.

Selecting this checkbox displays any warning (as errors), regardless of the state of the

Show Warnings checkbox in the General page; see the Show Warnings section on page 70.

Warn on Segment Overlap

This checkbox enables or disables warnings when overlap occurs while binding segments.

By default, the checkbox is selected, which is the recommended setting for Z8 Encore!.

An overlap condition usually indicates an error in project configuration that must be cor-

rected; however, the linker creates deliberate overlays for some functions when using

static frames, and these overlays are not reported as warnings. These errors in Z8 Encore!

can be caused either by user assembly code that erroneously assigns two or more segments

to overlapping address ranges or by user code defining the same interrupt vector segment

in two or more places.

Linker: Output Page

The options in the Output page are described in this section.
