Usage: $0 [OPTION] ... [TEMPLATE-FILE]
|
|
|
|
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 variable \`WARNINGS' is 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 report the list of calls to MACRO
|
|
-i, --initialization also trace Autoconf's initialization process
|
|
|
|
In tracing mode, no configuration script is created.
|
|
|
