Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
This macro sets VARNAME to the expansion of the DIR variable, taking care
of fixing up ${prefix} and such.
</p>
<p>
VARNAME is then offered as both an output variable and a C preprocessor
symbol.
</p>
<p>
Example:
</p>
<pre>
AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])
</pre>
</div>

test "x$prefix" = xNONE && prefix_NONE=yes && prefix=$ac_default_prefix

dnl In Autoconf 2.60, ${datadir} refers to ${datarootdir}, which in turn
dnl refers to ${prefix}. Thus we have to use `eval' twice.
eval ac_define_dir="\"[$]$2\""
eval ac_define_dir="\"$ac_define_dir\""
AC_SUBST($1, "$ac_define_dir")
