AC_ARG_WITH

[Russell Shaw]

Hi,

I'm learning autoconf packaging.

At the configure step, i want to specify:

  ./configure --with-default-size=5

and have appear in config.h: #define DEFAULT_SZ  5

In configure.ac, i have:

AC_ARG_WITH(
    [border_size],
    AC_HELP_STRING([--with-default-border-size],
                   [Set default border size]),
    [default_size = $withval],
    [default_size=3]
)

AC_DEFINE(DEFAULT_SZ,$default_size)


However, in config.h, all i get is:

  #define DEFAULT_SZ $default_size


How do i get:

  $define DEFAULT_SZ  5

??
