1 | dnl @synopsis AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) |
2 | dnl | |
3 | dnl This macro sets VARNAME to the expansion of the DIR variable, | |
4 | dnl taking care of fixing up ${prefix} and such. | |
5 | dnl | |
6 | dnl VARNAME is then offered as both an output variable and a C | |
7 | dnl preprocessor symbol. | |
8 | dnl | |
9 | dnl Example: | |

11 | dnl AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.]) | |

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