"Cannot create references" error

[A Former User]

Thanks for the patch! I did another “git pull” and tried the install again. I now get the same error, but in a different spot:

PHP Fatal error: Cannot create references to elements of a temporary array expression in /var/www/html/fog/lib/fog/fogbase.class.php on line 134

@dramaley What version of PHP are you running?

[A Former User]

It is the standard PHP on RHEL 7:

$ php --version
PHP 5.4.45 (cli) (built: Jan 6 2016 16:48:34)
Copyright 1997-2014 The PHP Group
Zend Engine v2.4.0, Copyright 1998-2014 Zend Technologies

@dramaley What version of fog are you running?

the Git tree, forces you to at least have 5.6.

Doh! When i originally installed Fog i was careful to check requirements, but have not rechecked those recently. I’ll look into getting PHP updated and report back if that fixes it.

@dramaley You didn’t do anything wrong. It’s only worrying me that if you’re running git pull and it’s NOT updating php to what I’m forcing, that something else is amiss and I don’t know what.

OK, so i stopped Apache, erased all php* packages, installed the php56-* packages in their place, and restarted Apache. Then i re-ran the Fog installer. And… it installed the original php* packages! So now i have 2 versions of PHP installed. And the old one takes precedence, so Fog is still not working.

I’ll try running the Fog installer again, but from a second terminal i’ll erase all the php* packages that the installer mistakenly installs and see if i can work around it that way.

[A Former User]

I got the latest Fog installed! The work-around that i described a few minutes ago worked.

@dramaley,

As you’re using git, can you output the exact commands being used?

[Tom Elliott]

Also, if possible the current hash of the git pull?

[A Former User]

Here is what i do to install Fog:

# cd fogproject
# git pull
# cd bin
# ./installfog.sh

Is this what you mean by the hash?

# git rev-parse HEAD
8ca213b6efd9fdc7b5df63deeac3b9cfd7fc1be0

That was run in the fogproject directory.

Hello,
I have the same error, just after the step :

• You still need to install/update your database schema.

• This can be done by opening a web browser and going to:

  http://192.168.222.14/fog/management

@Rico can you try the workaround steps @dramaley described? Your version of php is likely incorrect.
