autoscan - help to create a configure.ac file for a software package
autoscan [ --help | -h ] [ --version | -V ] [ --verbose | -v ] [
--autoconf-dir=dir | -A dir ]
The autoscan program can help you create a configure.ac file for a
software package. autoscan 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.ac for that package.
You should manually examine configure.scan before renaming it to con-
figure.ac; it will probably need some adjustments. Occasionally
autoscan outputs a macro in the wrong order relative to another macro,
so that autoconf 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 ifnames(1)), for information about a program
that can help with that job).
autoscan 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.
autoscan requires that a Perl interpreter is installed.
autoscan accepts the following options:
-h Print a summary of the command line options and exit.
-V Print the version number of Autoconf and exit.
-v Report processing steps.
-A 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.
