[Buildroot] [PATCH v1] package/php: fix aarch64 uclibc-ng compile

Peter Seiderer ps.report at gmx.net
Mon Mar 9 14:50:38 UTC 2020


The aarch64 compile uses the sys/auxv.h header which is not
provided by ulcibc-ng. Add configure.ac patch to check for
the header before using it in ext/standard/crc32.c.

Fixes:
