NAME

autoconf - Generate configuration scripts

SYNOPSIS

autoconf2.69 [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 [syntax]

Warning categories include:

`cross': cross compilation issues
`obsolete': obsolete constructs
`syntax': dubious syntactic constructs
`all': all the warnings
`no-CATEGORY': turn off the warnings on CATEGORY
`none': turn off all the warnings
`error': warnings are error

The environment variables `M4' and `WARNINGS' are honored.

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.
