autoconf - Generate configuration scripts


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


Generate a configuration script from a TEMPLATE-FILE if given, or ‘’ if present, or else ‘’. 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 compilation issues
 obsolete constructs
 dubious syntactic constructs
‘all’ all the warnings
 turn off the warnings on CATEGORY
‘none’ turn off all the warnings
 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


-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.
