configure option disable-memcached-sasl not working

[fabiocarneiro]

The options has effect on configure, but on the build it requests sasl.h anyway.

Btw, I'm using official docker fpm alpine (php:7.0.11-fpm-alpine), and to be able to install the extension (php7 branch), I had to install cyrus-sasl-dev.

It was hard to find, because there are thousands of packages with sasl in the name and php docs call it "libsasl2".

[sodabrew]

Please try php7 branch again.

Seems that issue is not resolved still.

Can be reproduced with following Dockerfile:

FROM php:7.0.12-fpm-alpine


RUN apk add --update --no-cache \
        libmemcached-libs zlib \
        ca-certificates \
 && update-ca-certificates \

 && apk add --no-cache --virtual .tools-deps \
        git autoconf g++ libtool make \
 && apk add --no-cache --virtual .build-deps \
        libmemcached-dev \
        zlib-dev \

 && docker-php-source extract \
 && git clone --branch php7 https://github.com/php-memcached-dev/php-memcached \
              /usr/src/php/ext/memcached/ \
 && docker-php-ext-configure \
           memcached --disable-memcached-sasl \
 && docker-php-ext-install \
           memcached

Results with following error on step docker-php-ext-install memcached:

In file included from /usr/include/libmemcached-1.0/memcached.h:85:0,
                 from /usr/include/libmemcached/memcached.h:39,
                 from /usr/src/php/ext/memcached/php_libmemcached_compat.h:21,
                 from /usr/src/php/ext/memcached/php_memcached_private.h:28,
                 from /usr/src/php/ext/memcached/php_memcached.c:25:
/usr/include/libmemcached-1.0/struct/sasl.h:39:23: fatal error: sasl/sasl.h: No such file or directory
compilation terminated.
Makefile:194: recipe for target 'php_memcached.lo' failed
make: *** [php_memcached.lo] Error 1

[sodabrew]

At least the error moved from inside the php-memcached headers to the libmemcached headers. I'll take a look if there are flags that should be set to skip the sasl.h include there, too.

[fabiocarneiro]

I don't need this option anymore (for now), since I managed to configure it with the sasl support, but I created the issue so it would be helpful for someone else.

[Tairy]

Install cyrus-sasl-dev can solve this problem.

[tyranron]

@Tairy yeap. But the point of this issue in --disable-memcached-sasl case.

[sodabrew]

This is not fixable. When libmemcached is compiled with SASL support, it writes out its header files in such a way that it always requires the sasl.h header even if you disable SASL support in php-memcached.
