在Debian和Ubuntu下如何编译PHP7

I’ve been reading great things about PHP 7, specifically the PHP7 infographic created by Zend. So today I decided to create a ubuntu droplet and go to work compiling php7 from source. I ran into a few problems along the way but eventually was successfully. Here is a quick howto that will help you avoid some the same pitfalls I experienced.

After installing a fresh copy of Ubuntu 14.04 lets install some dependencies and software we need to compile php from source.

A WORD OF CAUTION! Do not attempt to compile or install php7 on a production machine, you have been warned. While already published, this article is a work in progress and I’m still writing and editing it.

First Step, Install gcc compiler, php5 dependencies, and some required libraries.

You may also have to create this symbolic link

Next, create a folder to download to and use git to clone the php7 codebase.

Running buildconf and configure is next  You may want to adjust the paths of –prefix and –with-config-file-path if you are attempting to make and install php7 to coexist with a php5 installation.

And now, time to compile php7. This step might take a while depending on your machine. I first attempted to compile php7 on a DigitalOcean 512MB droplet and ran out of memory. Make sure your ubuntu machine has at least 1GB of RAM before proceeding.

The final step, install the compiled php7 binaries.

Now lets execute php -v and to confirm the we are indeed running php 7.

That’s it, your first taste of php7. If you run into errors during the configure step the answer might be below.

You may want to add: /root/php7/usr/lib/php to your php.ini include_path
/root/php7/php-src/build/shtool install -c ext/phar/phar.phar /root/php7/usr/bin

Solution
Install more RAM or increase the size of your VPS, it looks like 512MB is not enough to compile php7 from source.

Disk and Memory Requirements to compile PHP7

You will need atleast 1GB of RAM to compile php 7 on Ubuntu 14.04.
