Subject: [PATCH] ext/opcache: fix detection of shm/mmap
|
|
|
|
The detection of sysvipc and mmap doesn't work well when cross-compiling,
|
|
so I decided to only check for the availability of the functions involved.
|
|
This is not a clean solution, but works for now(tm) :-)
|
|
|
|
It should be discussed with upstream to find a better solution.
|
|
|
|
This solves the issue reported at
|
|
https://github.com/openwrt/packages/issues/1010
|
|
and makes opcache usable on OpenWrt.
