Error installing v8js

[tommymarshall]

I know this is only loosely related to your repo, but I thought getting an issue up would be a good reference for those of us debugging getting v8js installed.

Most of us use Laravel's Homestead vagrant box environment. I have a newly provisioned VM and, when I run the installation for v8js, I get the below error/output:

vagrant@homestead:~$ sudo pecl install v8js-beta

I ran pecl channel-update pecl.php.net, but the error persists. Any ideas?

V8js depends on libv8, run sudo apt-get install libv8-dev libv8-dbg g++ cpp before installing it with pecl (source).

Say me if that worked !

Thanks for opening the issue, I'm gonna update it at the README !

[tommymarshall]

Thanks for the quick response! There must be something funky with the Vagrant Box, because:

vagrant@homestead:~$ sudo apt-get install libv8-dev libv8-dbg g++ cpp
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libv8-dbg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libv8-dbg' has no installation candidate

I installed libv8 using gem install libv8. That got me further into the process, then:

vagrant@homestead:~$ sudo apt-get install libv8-dev libv8-dbg g++ cpp

Reading state information... Done
Package libv8-dbg is not available, but is referred to by another package.

vagrant@homestead:~$ sudo apt-get install libv8-dev g++

g++ is already the newest version.
libv8-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.

But then I don't have libv8-dpg or cppf :/ #tears

[talyssonoc]

I'm not sure thar libv8-dbg is really necessary (gotta check it later and them update the REAME me again, sorry by the inconvenient).

And I guess you commited a typo there, it's cpp, not cppf !

Try just this: sudo apt-get install libv8-dev g++.

Edit:

Just installed it in homestead using sudo apt-get install libv8-dev g++ :D When asked for libv8 location, use /opt/v8.

Thank you so much. /opt/v8 is the path I have been looking for.

God bless you.

Any ideas what to do when /opt/v8 doesn't exist? I have all the packages installed.
