[FIXED] How to install memcache extension (php72, macos Catalina)

Issue

I can't install memcache (not memcached) extension on MacOs Catalina, php 7.2

checking for the location of zlib... configure: error: memcache support requires ZLIB. Use --with-zlib-dir=<DIR> to specify prefix where ZLIB include and library are located
ERROR: `/private/tmp/pear/temp/memcache/configure --with-php-config=/usr/local/opt/php@7.2/bin/php-config --enable-memcache-session=yes' failed

I try

pecl install memcache --with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include/zlib.h

But

Attempting to discover channel "--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include"...
Attempting fallback to https instead of http on channel "--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include"...
unknown channel "--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include" in "--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include/zlib.h"
invalid package name/package file "--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11/include/zlib.h"

Solution

You're close... Your path should not to be the header file but to the directory. Also, pecl install doesn't pass the command line parameter in the script down to the ./configure command so you have to do it yourself:

pecl download memcache
open memcache-4.0.5.2.tgz  
cd memcache-4.0.5.2/memcache-4.0.5.2
phpize
./configure --with-zlib-dir=/usr/local/Cellar/zlib/1.2.11
make
sudo make install
