Forcing complete expansion of a variable

[Joshua Kwan]

Hi all,

My program has something like this in configure.in:

AC_ARG_WITH(musicpath,
        AC_HELP_STRING([--with-musicpath], [Path to install music files
        to (default: DATADIR/tetriword/music)]),
                musicpath=$withval,
                musicpath=${datadir}/${PACKAGE}/music)

So musicpath will default to ${datadir}/${PACKAGE}/music. This is good!

But later on:

if test $music = yes; then
echo "Music will be installed in     : $musicpath"
fi

This prints out:

Music will be installed in     : ${prefix}/share/tetriword/music

Ugh! Is there a non-hacky way that I can force the expansion of that
${prefix}?

(please CC me, i'm not subscribed to this list yet)

Regards,
Josh
