| 5 | # OBSOLETE MACRO | |
| 6 | # | |
| 7 | # Deprecated because it does not comply with the GNU Coding Standards. See | |
| 8 | # the autoconf manual section "Defining Directories" for alternatives. | |

| 10 | # SYNOPSIS | |
| 11 | # | |
| 12 | # AX_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) | |
| 13 | # | |
| 14 | # DESCRIPTION | |
| 15 | # | |
| 16 | # This macro sets VARNAME to the expansion of the DIR variable, taking | |
| 17 | # care of fixing up ${prefix} and such. | |
| 18 | # | |
| 19 | # VARNAME is then offered as both an output variable and a C preprocessor | |
| 20 | # symbol. | |
| 21 | # | |
| 22 | # Example: | |
| 23 | # | |
| 24 | # AX_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.]) | |
