autoscan2.13 - help to create a configure.in file for a software
autoscan2.13 [ --help ] [ --macrodir=dir ] [ --verbose ] [ --version ]
The autoscan2.13 program can help you create a configure.in file 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 preliminary configure.in for that package.
You should manually examine configure.scan before renaming it to
configure.in; it will probably need some adjustments. Occasionally
autoscan2.13 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).
autoscan2.13 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 # are comments.
autoscan2.13 requires that a Perl interpreter is installed.
autoscan2.13 accepts the following options:
-h 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.
