Cannot enable libmemcached protocol

[panosru]

I have libmemcached-dev installed (latest version) and when I run pecl install memcached

I'm getting:

checking for memcached protocol support... enabled
checking whether libmemcachedprotocol is usable... no
configure: error: Cannot enable libmemcached protocol

With 3.0.4 works fine.

Same issue with PHP 7.3 and memcached-3.1.1

@blkperl I'm on PHP 7.2.13 (docker php-fpm)

3.1.2 released, please confirm if resolved now!

@sodabrew just checked and it worked for me (php-fpm 7.2.13/docker)

@sodabrew works for me PHP 7.3/Ubuntu Xenial docker.

Obviously that is working because it passes --enable-memcached-protocol=no, but what if is needed?

[sodabrew]

I haven't personally tested server protocol support, and I don't see unit tests for it. I'm not sure what the use case would be for the PHP module. Existence of this code predates my role as maintainer.

The libmemcached library has to be compiled to provide server protocol support, by default (and in most distributions) it is disabled:
