NodeBuilder Errors Guide 5-57
NCC# Description
456
The directive ‘#pragma num_alias_table_entries’ is required
[NCC#456]
A Neuron C program must specify to the Neuron C Version 2
compiler how much room is to be reserved for the alias table. The
compiler does not attempt to compute a default, so the programmer
must
specify a value for this pragma. Previous versions of the
Neuron C Compiler defaulted this value to zero, but that is really not
an appropriate default value.
The value 0 (zero), however, can still be used to effectively disable
the use of the alias feature; please see the Neuron C Reference Guide
for more about compiler directives.
457
The type used in the declaration is unnamed or unsupported
[NCC#457]
Some types are not supported when compiling a program that is used
as a Neuron C model file for ShortStack host development. Consult
the ShortStack User's Guide for more information.
458 The fblock’s property is a duplicate [NCC#458]
The L
ONMARK Application Layer Interoperability Guidelines specify
that no more than one property of any particular SCPT or UCPT type
may be used for a functional block. Consult that document for more
information.
459
Node object must be first fblock for LNS versions before 3.2
[NCC#459]
For LNS versions prior to version 3.2, if the device has a node object,
that node object must be the first functional block declared in the
device (and therefore, the functional block with global index zero).
460 Cannot use an inheriting type to declare this object [NCC#460]
Some CPTs require inheritance of type information from a network
variable. Type inheritance is a feature that only applies to
configuration properties. Use of such a CPT for any other purpose
(for example, declaring a local or static variable in the program, or
declaring a function parameter or pointer) results in a declaration
with incomplete type information(since only a configuration property
can inherit a type from a network variable). A declaration with an
incomplete type is not valid.
The CPT used in the declaration can only be used as part of a
configuration property declaration.
461
Cannot use an inheriting type CP as a device property
[NCC#461]
A configuration property declared using a CPT type that inherits
from a network variable could not be a device property, because in
that situation there is no network variable from which to inherit.
