4.1 Initializing configure

Every configure script must call AC_INIT before doing anything else. The only other required macro is AC_OUTPUT (see section 4.4 Outputting Files).

Macro: AC_INIT (package)

Process any command-line arguments and perform various initializations and verifications. Set the name of the package and its version. The optional argument bug-report-address should be the email to which users should send bug reports.

These three arguments must be static, i.e., there must not be any shell computation, but they can be computed by M4. The following macros and output variables are then defined:

AC_PACKAGE_NAME, PACKAGE_NAME

Exactly package.

AC_PACKAGE_TARNAME, PACKAGE_TARNAME

package once `GNU ' strip, and lower cased.

AC_PACKAGE_VERSION, PACKAGE_VERSION

Exactly version.

AC_PACKAGE_STRING, PACKAGE_STRING

Exactly `package version'.

AC_PACKAGE_BUGREPORT, PACKAGE_BUGREPORT

Exactly bug-report-address.
