Recompile PHP with ZTS enabled on Ubuntu

Question

I am trying to install pthreads by using

pecl install pthreads

But I got this error during the installation

configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled

I have searched for this error. It seems that I have to install a new version of PHP with ZTS enabled. Is there any simpler ways to recompile with ZTS enabled instead of reinstalling PHP?

Here is the quoted answer from a Digital Ocean community comment:

ZTS support is a configure time option and can not be enabled at run time. You'll need to build php yourself with the --enable-maintainer-zts flag in order to enable it.

One way to do this is to modify the existing package and rebuild it. First we'll need to install and download a few things:

Install the build dependencies:

sudo apt-get build-dep php5

Install the developer tools:

sudo apt-get install devscripts

Download the source:

apt-get source php5

Now enter the source directory and edit the debian/rules file:

cd php5-5.5.9+dfsg/    # The version will be different depending on the Ubuntu release
nano debian/rules

Find the section starting with COMMON_CONFIG=--build=$(DEB_BUILD_GNU_TYPE) \ and add the following configure flags:

        --enable-maintainer-zts \
        --enable-pthreads \

Then we want to bump the version number for the package, so that it is higher than the version of PHP in the repository. Run dch -i and create a new changelog entry:

php5 (5.5.9+dfsg-1ubuntu4.5+zts1) trusty; urgency=medium

  * Rebuild with ZTS support.

Now the package can be built using the command:

DEB_BUILD_OPTIONS=nocheck debuild

This will take quite awhile and will also require some memory. If you're on a 512mb server, you'll probably need to add some swap.

It will produce a number of packages in the parent directory:

cd ..
ls *deb

You can now install the individual packages with sudo dpkg -i pakage_name.deb or all of them with sudo dpkg -i *deb
