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.]) | |
