      Just for clarity what specifically is “the latest from git” for your install. Latest is a moving target these days.

      Second, when you updated from git, did you do that while you were in the fog trunk directory or from within the bin folder? (just recently I saw someone running the download from the bin folder, which will only update the installfog.sh file)

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        I have a directory called “fogproject” from when I initially installed Fog. I did a “git pull” from within that directory to make it current, then did a “cd bin ; ./installfog.sh” to run the installer. I think this shows what version I’m working with; these commands were run in the fogproject directory:

        # git describe --tags
        v1.3.0-beta.3510-2774-gfb42d97
        # git log -1
        commit fb42d97355ff12ad540bfde3edc6ee02f0d1a909
        Merge: b6bfde0 fd40b38
        Author: Tom Elliott <tommygunsster@gmail.com>
        Date:   Mon Feb 15 16:34:29 2016 -0500
        
            Merge svn with dev-branch
        # git rev-parse HEAD
        fb42d97355ff12ad540bfde3edc6ee02f0d1a909
        

        I will try to upload the installation error log as well: 0_1455586835861_fog_error_6283.log

          I removed the value being passed my reference. With any luck, this error will be gone and solved.

              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

                  It is the standard PHP on RHEL 7:

                  $ php --version

                    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.

                            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?

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

                                  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.
