Compiler Option: -w
Set minimum warning level.
Syntax:
-w level | all | none | param | escape | pedantic | next | funcptr | constness | suffix
Parameters:
level
escape
Warning messages only with a level equal or greater to this value will be output.
all
Equivalent to specifying a level of negative one (-1).
none
Suppresses all warnings.
paramescape
Warn when string literals contain any number of escape characters (\).
pedantic
Equivalent to specifying the param and escape arguments, plus length checking of parameters passed ByVal and of any Cptr converting to pointer only, plus warning on useless suffixes in '-lang fb'.
next
Warn when Next is followed by an identifier.
funcptr
Warn on mismatched procedure pointers, including conversions in CAST and CPTR expressions. Implies '-w all'. Experimental. Behaviour may change in future versions.
constness
Warn when CONST (Qualifier) is discarded in an assignment. Implies '-w funcptr' and '-w all'. Behaviour may change in future versions.
suffix
Warn on useless suffixes in '-lang fb'.
Description:
The -w compiler option determines which compiler warnings, if any, are output. Each possible warning is associated with a warning level, starting from negative one (-1) and increasing with the potential problems that may occur.
The param, escape, pedantic, next, funcptr, and constness arguments provide additional warnings not ordinarily output, even by default.
The default, if the -w option is not specified, is as if -w 0 was used. The -w option can be specified multiple times. Warning messages having a level of -1 are not shown by default.
-w none, or a significantly high level value will have the effect of suppressing all warning messages.
For fbc version >= 1.08: Warning level for all warnings is increased by 1. Default warning level is 1 (previously, default warning level was 0 and some warnings had level of -1).
