autoheader1

Create a template header for configure

Usage

autoheader [OPTION] ... [TEMPLATE-FILE]

Overview

Create a template file of C '#define' statements for 'configure' to use. To this end, scan TEMPLATE-FILE, or 'configure.ac' if present, or else 'configure.in'.

-h, --help: print this help, then exit

-V, --version: print version number, then exit

-v, --verbose: verbosely report processing

-d, --debug: don't remove temporary files

-f, --force: consider all files obsolete

-R, --replace-handwritten: overwrite an existing template file that appears not to have been generated by autoheader

-W, --warnings=CATEGORY: report the warnings falling in CATEGORY (comma-separated list accepted)

Warning categories are:

`cross`	cross compilation issues
`gnu`	GNU coding standards (default in gnu and gnits modes)
`obsolete`	obsolete features or constructions (default)
`override`	user redefinitions of Automake rules or variables
`portability`	portability issues (default in gnu and gnits modes)
`portability-recursive`	nested Make variables (default with `-Wportability`)
`extra-portability`	extra portability issues related to obscure tools
`syntax`	dubious syntactic constructs (default)
`unsupported`	unsupported or incomplete features (default)

-W also understands:

`all`	turn on all the warnings
`none`	turn off all the warnings
`no-CATEGORY`	turn off warnings in CATEGORY
`error`	treat all enabled warnings as errors

Library directories:

-B, --prepend-include=DIR: prepend directory DIR to search path

-I, --include=DIR: append directory DIR to search path
