NAME

autoconf - Generate configuration scripts

SYNOPSIS

autoconf [ ,OPTION/]... [,TEMPLATE-FILE/]

DESCRIPTION

Generate a configuration script from a TEMPLATE-FILE if given, or 'configure.ac' if present, or else 'configure.in'. Output is sent to the standard output if TEMPLATE-FILE is given, else into 'configure'.

Operation modes:

-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

-o, --output=,FILE/: save output in FILE (stdout is the default)

-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

Tracing:

-t, --trace=,MACRO[/:FORMAT]: report the list of calls to MACRO

-i, --initialization: also trace Autoconf's initialization process

In tracing mode, no configuration script is created. FORMAT defaults to '$f:$l:$n:$%'; see 'autom4te --help' for information about FORMAT.
