NAME
ifnames2.13 - print identifiers that a package uses in C preprocessor
conditionals
SYNOPSIS
ifnames2.13
[
--help
|
-h
] [
--macrodir=dir
|
-m dir
] [
--version
]
DESCRIPTION
ifnames2.13
can help when writing a
configure.in
for a software
package. It prints the identifiers that the package already uses in C
preprocessor conditionals. If a package has already been set up to
have some portability, this program can help you figure out what its
configure
needs to check for. It may help fill in some gaps in a
configure.in
generated by
autoscan2.13
(see
autoscan2.13(1)).
ifnames2.13
scans all of the C source files named on the command line
(or the standard input, if none are given) and writes to the standard
output a sorted list of all the identifiers that appear in those files
in
#if,
#elif,
#ifdef,
or
#ifndef
directives. It prints each
identifier on a line, followed by a space-separated list of the files
in which that identifier occurs.
ifnames2.13
accepts the following options:
- --help
-
- -h
-
Print a summary of the command line options and exit.
- --macrodir=DIR
-
- -m DIR
-
Look for the installed macro files in directory DIR. You can also
set the
AC_MACRODIR
environment variable to a directory; this
option overrides the environment variable.
- --version
-
Print the version number of Autoconf and exit.
