autoscan2.13 - help to create a configure.in file for a software package
] [ --macrodir=dir

program can help you create a configure.in
for a software package. autoscan2.13
examines source files in the
directory tree rooted at a directory given as a command line argument, or the
current directory if none is given. It searches the source files for common
portability problems and creates a file configure.scan
which is a
for that package.
You should manually examine configure.scan
before renaming it to
; it will probably need some adjustments. Occasionally
outputs a macro in the wrong order relative to another
macro, so that autoconf2.13
produces a warning; you need to move such
macros manually. Also, if you want the package to use a configuration header
file, you must add a call to AC_CONFIG_HEADER
. You might also have to
change or add some #if
directives to your program in order to make it
work with Autoconf (see ifnames2.13
(1)), for information about a
program that can help with that job).
uses several data files, which are installed along with the
distributed Autoconf macro files, to determine which macros to output when it
finds particular symbols in a package's source files. These files all have the
same format. Each line consists of a symbol, whitespace, and the Autoconf
macro to output if that symbol is encountered. Lines starting with #
requires that a Perl interpreter is installed.
accepts the following options:
- Print a summary of the command line options and exit.
- -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.
- Print the names of the fiels it examines and the
potentially interesting symbols it finds in them. This output can be
- Print the version number of Autoconf and exit.
