Resolved php7 and memcached - again

and for ubuntu?

What is the problem with Ubuntu?

What is the problem with Ubuntu?

Just tested it now. All works fine with 16.04 and php7.1, not sure that it works, but it is installed and enabled in Plesk now!
There were some dependencies and some other package names:
apt install plesk-php71-dev pkg-config zlib1g-dev libmemcached-dev

P.S. read also an article about server load reduction which is related to memcached php7.

Sorry for bumping an old thread, but I run into an issue. A customer wants Memcached on his PHP 7.0.

I followed the tutorial IgorG to the letter, however I run into a problem. When I run the 'make' command I get the following error:

Any idea?

The customer is on CentOS 6.9 (Final).

Thanks in advance.

//edit

I also tested the above on a server of ourselves, which is clean and also is running on CentOS 6.9 (Final). I get the same exact issue there... :S

 

[IgorG]

# ./configure --disable-memcached-sasl --with-php-config=/opt/plesk/php/7.0/bin/php-config

Was this command completed without errors?

 

[HHawk]

Yeah, was without issues. I just ran the command on one of our own servers once again:

On a CentOS 7.x server it works all without issues, but using different commands there though (didn't work on CentOS 6.x obviously).

I offered the customer to redo the installation of his server with CentOS 7.x and Onyx as well. He didn't mind the downtime.
So there is no rush, but I still would like to know why it doesn't work on our servers with CentOS 6.x, because it should, right?

 

[IgorG]

I suppose that this may be related to outdated gcc and g++ on CentOS6
Try to update it with

# yum install centos-release-scl
# yum install devtoolset-3-toolchain
# scl enable devtoolset-3 bash

After that try to compile module again. I hope it will help.

Any other ideas?

Please double check that libmemcached-devel is really and correctly installed.

Sorry for the late reply, but was out a few days with the flu (still not feeling well, but duty calls...).

I am pretty sure that libmemcached-devel is correctly installed. Not much can go wrong with the use of yum for it imho.
See:

yum install  libmemcached-devel
Package libmemcached-devel-0.31-1.1.el6.x86_64 already installed and latest version

So that's not it. To make sure I removed it and reinstalled it again, but still the same issue...

You have outdated version of this package. Have you read this post #7 ?

 

[HHawk]

I actually did read that, however I thought those versions were even older and also it's for i686 not x86_64?

 

[IgorG]

Install it for x86_64 if you have 64bit OS version. Look, by default there is very old version:

# rpm -qi libmemcached | grep "Build Date"
Release : 1.1.el6 Build Date: Fri 12 Nov 2010 02:48:23 AM NOVT

 

[IgorG]

For example, x86_64 packages:

# wget https://packages.inverse.ca/SOGo/nightly/2/rhel/6/x86_64/RPMS/libmemcached-devel-1.0.18-1.x86_64.rpm
# wget https://packages.inverse.ca/SOGo/nightly/2/rhel/6/x86_64/RPMS/libmemcached-1.0.18-1.x86_64.rpm

I really thought YUM would automatically install the latest version. My bad.
Sorry IgorG and thanks again for explaining. Will give this a new go. Highly appreciated.
