| 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]) |
