5-38 Neuron C Compiler Errors (NCC)

NCC# Description

275 Recommend use of 'fails' or 'succeeds' event instead [NCC#275]

This message indicates that the call to a completion event can be

changed to a fails or succeeds event as an efficiency consideration.

See the discussion on events in the Neuron C Programmer’s Guide or

the Neuron C Reference Guide.

276

The 'preempt_safe' keyword has no effect on this 'when' clause

[NCC#276]

Some when clauses and their associated tasks will be executed

regardless of preemption mode. Use of the preempt_safe keyword

for this type of when clause is unnecessary, and has no effect.

291 Improper binary constant ‘<value>’ [NCC#291]

A binary constant begins with 0b and is followed by one or more

binary digits, (i.e. the digits 0 or 1).

292 Incomplete hexadecimal constant ‘<value>’ [NCC#292]

A hexadecimal constant begins with 0x and must be followed by one

or more hexadecimal digits, (i.e. the digits 0-9, and the letters a-f and

A-F).

293 Improper octal constant ‘<value>’ [NCC#293]

An octal constant begins with 0, and must be followed by one or more

octal digits, (i.e. the digits 0-7).

294 Unterminated character constant: ‘<value>’ [NCC#294]

The proper format of a character constant is ‘char’. The ‘char’ can

either be a single character (except another quote ), or any of a

number of ANSI C escape sequences. Consult a basic text on ANSI

C, such as one of those listed in the Preface of the Neuron C Reference

Guide, for more information.

295 Integer constant ‘<string>’ is too large [NCC#295]

Integer constants are limited to 5 characters, with a value of 65535

or less, since the maximum size of an integer is 16 bits.

297 Cannot open <filetype> file: ‘<filename>’ [NCC#297]

The file that is named cannot be found. Check the spelling of the

filename and check the Application Directories’ and Include

Directories’ search paths in the development tool’s settings or the

command line being used to execute the compiler.

298

Recursive include file nesting (file ‘<filename>’) not allowed

[NCC#298]

An include file cannot include itself, nor can any file B included from

file A then re-include file A, etc.

299 Unsupported preprocessor directive: ‘<name>’ [NCC#299]

The following ANSI C preprocessor directives are not supported in

Neuron C:

#elif

#file

#if

#line

1 2 ... 53 54 55 56 57 58 59 60 61 62 63 ... 122 123
