| 6 # | |
| 7 # AX_REQUIRE_DEFINED(MACRO) | |
| 8 # | |
| 9 # DESCRIPTION | |
| 10 # | |
| 11 # AX_REQUIRE_DEFINED is a simple helper for making sure other macros have | |
| 12 # been defined and thus are available for use. This avoids random issues | |
| 13 # where a macro isn't expanded. Instead the configure script emits a | |
| 14 # non-fatal: | |
| 15 # | |
| 16 # ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found | |
| 17 # | |
| 18 # It's like AC_REQUIRE except it doesn't expand the required macro. | |
| 19 # | |
| 20 # Here's an example: | |
| 21 # | |
| 22 # AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG]) | |
