error when installing pecl memcached

Question

I've been having real trouble installing the pecl memcached package.

Have not had any joy with any yum or pear/pecl install commands I referred to this question Install PECL Memcached Error and started trying to configure/make manually

I'm using pecl to download the latest (memcached-2.2.0) then untar, phpize...

If I configure with --disable-memcached-sasl the configure completes but make fails. With what looks like syntax errors

In file included from /root/memcached-2.2.0/php_memcached_private.h:28,
                 from /root/memcached-2.2.0/php_memcached.c:26:
/root/memcached-2.2.0/php_libmemcached_compat.h:56: error: expected ‘=’, ‘,’, ‘;’, ‘asm’     or ‘__attribute__’ before ‘php_memcached_instance_st’
/root/memcached-2.2.0/php_memcached.c:328: error: expected declaration specifiers or ‘...’ before ‘php_memcached_instance_st’
/root/memcached-2.2.0/php_memcached.c:329: error: expected declaration specifiers or     ‘...’ before ‘php_memcached_instance_st’
/root/memcached-2.2.0/php_memcached.c:330: error: expected declaration specifiers or ‘...’ before ‘php_memcached_instance_st’
/root/memcached-2.2.0/php_memcached.c: In function ‘php_memc_get_impl’:
/root/memcached-2.2.0/php_memcached.c:594: warning: passing argument 4 of     ‘memcached_mget_by_key’ from incompatible pointer type
/usr/include/libmemcached/memcached_get.h:38: note: expected ‘char **’ but argument is of type ‘const char **’
/root/memcached-2.2.0/php_memcached.c: In function ‘php_memc_getMulti_impl’:

There's more of that but hopefully thats a useful enough indicator

If I use --with-libmemcached-dir=/usr/include/libmemcached i get

checking for libmemcached location... configure: error: Unable to find memcached.h under /usr/include/libmemcached

But that IS where memcached.h is

If I use --with-libmemcached-dir=no configure gives

configure: error: no, libmemcached sasl support is not enabled. Run configure with --disable-memcached-sasl to disable this check

If i add the --disable-memcached-sasl option, it configure completes but make fails with the syntax errors again

Feel like I'm stuck in a loop.

This isn't the first time I've set up a server from scratch to use memcached (although first time in a while I guess) I don't remember having any issues before.

Any ideas please anyone?

This looked like a good lead

But not joy still

I've also been investigating this issue from php-memcached's github page

https://github.com/php-memcached-dev/php-memcached/issues/69

I've tried with 2.1 and 2.2 now, hacking the files to try and get make to build. Still no luck...

Answer 1

On CentOS 7.2 with installed libmemcached-devel version 1.0.16 you should answer the question with /usr:

libmemcached directory [no] : /usr

Answer 2

Step 1 - Install SASL:

yum install cyrus-sasl-devel

Step 2 - Compile libmemcached with SASL installed:

cd ~
wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
tar -zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure
make && make install

Step 3 - Install PHP Memcached:

pecl install memcached

(Do not specify libmemcached-dir)

Answer 3

Steps:

1. sudo apt-get install libmemcached libmemcached-dev
2. sudo mkdir -p /usr/lib/x86_64-linux-gnu/include/libmemcached && sudo ln -s /usr/include/libmemcached/memcached.h /usr/lib/x86_64-linux-gnu/include/libmemcached/memcached.h
3. echo "/usr/lib/x86_64-linux-gnu --disable-memcached-sasl" | sudo /opt/phpfarm/inst/php-5.4.40/bin/pecl -C /opt/phpfarm/inst/php-5.4.40/etc/pear.conf install memcached

Setup: Ubuntu 14.04.x LTS x64 (trusty tahr) phpfarm (latest) with pecl PHP 5.4.40 memcached 2.2.0

NOTE: Obviously, you must replace the paths according to your system

Answer 4

The procedure @rynop is very good and its all great!

Now how about you want to package for deployment? My target deployment runs on Ubuntu 14.04 LTS and I want it to replace upstream php5-memcached package as a simple .deb file.

For this, take a look at fpm which stands for "Freaking Package Manager" (sic). Its made to create packages out of almost anything.

After @rynop procedure, here’s what I did:

// Rest of @rynop procedure, modulo this configure options
./configure --enable-memcached-igbinary --disable-memcached-sasl

Install jordansissel/fpm

apt-get install -y pkg-config ruby-dev gcc
gem install fpm

Then, check the package contents you want to replace and let’s replicate for our own purposes.

dpkg --list | grep php5-memcached
find /var/cache/apt -type f -name '*php5-memcached*'
dpkg -c /var/cache/apt/archives/php5-memcached_2.1.0-6build1_amd64.deb

I figured out in the output that I only needed a few folders, so I created them.

mkdir -p etc/php5/mods-available/
// Adjust memcached.ini to suit your tastes, then prepare it for packaging
cp memcached.ini etc/php5/mods-available/
// Make sure the usr/lib/php5/foo path matches in 
// the result of `dpkg -c` you issued
mkdir -p usr/lib/php5/20121212/
cp modules/memcached.so usr/lib/php5/20121212/

Magic will happen

fpm -s dir -t deb -n php5-memcached -v 2.2.0-wpd -m '<your@email.org>' --description 'PHP 5.5 PECL igbinary + memcached support' -d libmemcached10 etc/ usr/

Answer 5

If you don't need SASL, answer with this:

libmemcached directory [no] : no --disable-memcached-sasl

Answer 6

If you dont need sasl support here is an easy way to install 2.2.X:

pecl_memcached_ver="2.2.0"
pecl download memcached-${pecl_memcached_ver}
tar xzvf memcached-${pecl_memcached_ver}.tgz
cd memcached-${pecl_memcached_ver}/
phpize
./configure --disable-memcached-sasl
make
make install
cd ..
rm -r memcached-${pecl_memcached_ver}
echo "extension=memcached.so" > /etc/php5/fpm/conf.d/20-memcached.ini

Then run php5 -i to test that it installed 2.2.x correctly

Answer 7

Solved it by using this combination:

1. libmemcached release 1.0.16 - installed from source
2. php-memcached release 2.1.0 - installed from source & Added memcached.so in php.in

I Hope this help.
