4.3 Options to specify the Language for the Output Code

These options are also available as declarations in the input file (see Gperf Declarations).

‘-L generated-language-name’

‘--language=generated-language-name’

Instructs gperf to generate code in the language specified by the option's argument. Languages handled are currently:

‘KR-C’

Old-style K&R C. This language is understood by old-style C compilers and ANSI C compilers, but ANSI C compilers may flag warnings (or even errors) because of lacking ‘const’.

‘C’

Common C. This language is understood by ANSI C compilers, and also by old-style C compilers, provided that you #define const to empty for compilers which don't know about this keyword.

‘ANSI-C’

ANSI C. This language is understood by ANSI C compilers and C++ compilers.

‘C++’

C++. This language is understood by C++ compilers.

The default is ANSI-C.

‘-a’

This option is supported for compatibility with previous releases of gperf. It does not do anything.

‘-g’

This option is supported for compatibility with previous releases of gperf. It does not do anything.
