The error here is configure.ac:9: error: AC_INIT should be called with package and version arguments
.
You are getting this error because on line 9 of your configure.ac you are not passing package and version arguments to AC_INIT.
The exact information can be found here: https://www.gnu.org/software/automake/manual/automake.html#Public-Macros
Namely,
If your configure.ac has:
AC_INIT([src/foo.c])
AM_INIT_AUTOMAKE([mumble], [1.5])
You should correct it as follows:
AC_INIT([mumble], [1.5])
AC_CONFIG_SRCDIR([src/foo.c])
AM_INIT_AUTOMAKE
Although the other notes around it are important too imho.
