dnl @synopsis AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
|
|
dnl
|
|
dnl This macro sets VARNAME to the expansion of the DIR variable,
|
|
dnl taking care of fixing up ${prefix} and such.
|
|
dnl
|
|
dnl VARNAME is then offered as both an output variable and a C
|
|
dnl preprocessor symbol.
|
|
dnl
|
|
dnl Example:
|
|
dnl
|
|
dnl AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])

|
|
dnl In Autoconf 2.60, ${datadir} refers to ${datarootdir}, which in turn
|
|
dnl refers to ${prefix}. Thus we have to use `eval' twice.
