Installing PHPv8js on Ubuntu

Question

I'm having some trouble installing phpv8js on Ubuntu.

I've made sure I have a recent version of libv8 installed and have the required version of PHP but the install fails using PECL.

Here's the output:

libtool: compile:  g++ -I. -I/tmp/pear/temp/v8js -DPHP_ATOM_INC -I/tmp/pear/temp/pear-build-rootFyySRS/v8js-0.1.2/include -I/tmp/pear/temp/pear-build-rootFyySRS/v8js-0.1.2/main -I/tmp/pear/temp/v8js -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /tmp/pear/temp/v8js/v8js.cc  -fPIC -DPIC -o .libs/v8js.o

The only suggestions I've seen are to edit the package contents to define PHP_V8_VERSION but that seems a little hacky :)

You need to detail a little better which versions you are building against, and which build system, your procedure, etc. It's tricky business anyway. – Fendley

Answer 1

You can type the following and you should be able to install v8js for php.

    sudo apt-get install libv8-dev libv8-dbg g++ cpp

Then type:

   sudo pecl install v8js-0.1.3

Add to php.ini :

    extension=v8js.so

This should be marked as best answer - it worked for me! Thanks! – Shoemake

0.1.3 is kinda very old version, his date was released from year 2012. Then use it: sudo pecl install v8js-1.3.1 (relased date: 2016-07-02) – Kapp

i have a question, i have already installed v8js-0.1.3 what should i do if i want 1.3.1? – Manizales

Answer 2

sudo apt-get install libv8-dev libv8-dbg g++ cpp

if you are getting error "Package 'libv8-dbg' has no installation candidate".

Then Try.

1. sudo apt-get install libv8-dev g++

2. sudo pecl install v8js-0.1.3

3. "extension=v8js.so" to to your php.ini

if you are getting "pecl: command not found" then install

php-pear package for the pecl

sudo apt-get install php-pear php5-dev

and try step 2
