5.3 Options to specify the Language for the Output Code

These options are also available as declarations in the input file (see section 4.1.1.2 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.
