Subject: [PATCH] unix/uxutils.h: fix build on uclibc
|
|
Build on uclibc is broken since version 0.75 and commit
|
65383082bf0c49cec63f4b36001a40bd9b13edf6 because AT_HWCAP2 is used
|
even if <sys/auxv.h> is not available:
|
|
unix/uxutils.c: In function 'platform_aes_hw_available':
|
unix/uxutils.c:13:22: error: 'AT_HWCAP2' undeclared (first use in this function)
|
13 | return getauxval(AT_HWCAP2) & HWCAP2_AES;
|
| ^~~~~~~~~
|
|
To fix this build failure, include <elf.h>
|
|
