5-40 Neuron C Compiler Errors (NCC)
NCC# Description
309 Incomplete binary constant ‘<token>’ [NCC#309]
A binary constant begins with 0b and must be followed by one or
more binary digits, (i.e. the digits 0 or 1).
310 The symbol ‘<name>’ was declared but never used [NCC#310]
The compiler issues this warning for any run-time object that is
declared, but never used in the executable code. Run-time objects
include anything that consumes Neuron memory or other run-time
resources, such as I/O objects, variables, functions, timers, etc. No
warning is issued for compile time objects, such as typedefs,
structure tags, etc., which are not used. Some objects may be
intentionally declared, but unused. If it is desired to suppress this
warning for a certain symbol, the following pragma may be inserted
following the declaration of the object in question:
#pragma ignore_notused symbol
This directive may be used multiple times, for each symbol for which
the warning should be suppressed.

Redefinition of ‘<macroname>’ hides function [NCC#311]
Redefinition of ‘<macroname>’ hides enum value [NCC#312]
Redefinition of ‘<macroname>’ hides label [NCC#313]
The macro being defined, by the rules of ANSI C, will supersede any
other declarations of the same name. This may not be what the
programmer intended, so if a conflict is detected, to help with
detection of inadvertent programming errors, the above warning(s)
will be printed.
314 Cannot redefine ‘<name>’ [NCC#314]
The name has been declared as a certain type of identifier more than
once in the scope. For example, it is illegal to define a variable twice
at file scope, or a function, or a macro, etc. (however, there may be
multiple extern declarations for the same variable). Note that a
macro definition is always considered to be at file scope, regardless of
its placement in a file.
315
316
Name of network variable, ‘<name>’, exceeds 16 chars
[NCC#315]
Name of msg_tag, ‘<name>’ exceeds 16 chars [NCC#316]
Any network variable or message tag name is limited to 16
characters. Likewise, if a typedef name is used in declaration of a
network variable, it too must be 16 characters or less in length.
317 Label ‘<name>’ is not defined [NCC#317]
The specified label used in a goto statement is not defined in the
current procedure or task.
