| Subject: lib/raid6: Let $(UNROLL) rules work with macOS userland |
| |
| From: John Millikin <john@john-millikin.com> |
| |
| [ Upstream commit 0c36d88cff4d72149f94809303c5180b6f716d39 ] |
| |
| Older versions of BSD awk are fussy about the order of '-v' and '-f' |
| flags, and require a space after the flag name. This causes build |
| failures on platforms with an old awk, such as macOS and NetBSD. |
| |
| Since GNU awk and modern versions of BSD awk (distributed with |
| FreeBSD/OpenBSD) are fine with either form, the definition of |
| 'cmd_unroll' can be trivially tweaked to let the lib/raid6 Makefile |
| work with both old and new awk flag dialects. |
