Hi
I decided to install openemr manually using UniformServer and latest openemr
I extracted, created database, privileges, etc. and all went great until step 4, php-gacl

I’m getting this error in logs

[Wed Dec 14 21:06:39.877235 2016] [php7:error] [pid 4616:tid 1728] [client ::1:54477] PHP Fatal error:  Cannot unset $this in D:\\openemr\\UniServerZ\\www\\hc\\library\\adodb\\adodb-xmlschema.inc.php on line 160, referer: http://localhost/hc/setup.php

This is where I’m getting stuck

In case someone is wondering… UniformServer is one of the most lightweight WAMP environments with latest versions of php, mysql, apache, etc. all configured to be the most portable possible.
That’s why I dediced to go manually. I need a fast server in a not so fast workstation, which xampp does not help much in this way

Hi Enrique,

Guessing the simple answer will be that it is related to UniformServer, but perhaps there is a php7 bug here that can be addressed. What version of OpenEMR are you installing?

This is what I get from attempting to install Openemr 4.2.2. (Windows) via Xampp 7.1.1 on Macos Sierra

Hi Ben,

Try to use the following OpenEMR package instead which as I recall uses an updated adodb library (guessing this errors stems from the newer php version you are using):
http://opensourceemr.com/cvs/openemr-500-cvs.tar.gz
(this is a daily build from the openemr 5.0.0 development version)

Note will be releasing 5.0.0 tomorrow, so could then use that package when it’s out.

Thanks Brady, I will wait for the 5.0.0 tomorrow

I have tried now with the Linux 5.0.0 and got to this point, (not sure if I should use the Windows versions?)

We will now ensure correct file and directory permissions before starting installation:
Ensuring following files are world-writable…
‘/Applications/XAMPP/xamppfiles/htdocs/openemr-5.0.0/sites/default/sqlconf.php’ file is ready.
‘/Applications/XAMPP/xamppfiles/htdocs/openemr-5.0.0/interface/modules/zend_modules/config/application.config.php’ file is ready.

Ensuring following directories have proper permissions…

UNABLE to open directory ‘/Applications/XAMPP/xamppfiles/htdocs/openemr-5.0.0/sites/default/documents’ for writing by web server.
(configure directory permissions; see below for further instructions)

UNABLE to open directory ‘/Applications/XAMPP/xamppfiles/htdocs/openemr-5.0.0/sites/default/edi’ for writing by web server.
(configure directory permissions; see below for further instructions)

UNABLE to open directory ‘/Applications/XAMPP/xamppfiles/htdocs/openemr-5.0.0/sites/default/era’ for writing by web server.
(configure directory permissions; see below for further instructions)

(configure directory permissions; see below for further instructions)

You can’t proceed until all directories are ready.
In linux, recommend changing owners of these directories to the web server. For example, in many linux OS’s the web server user is ‘apache’, ‘nobody’, or ‘www-data’. So if ‘apache’ were the web server user name, could use the command ‘chown -R apache:apache directory_name’ command.
Fix above directory permissions and then click the ‘Check Again’ button to re-check directories.

Hi Ben,

Try the Windows file (this is a zip package). And if still not working then need to set write privileges for apache the above directories. See section at bottom of this wiki page for setting permissions in mac:

Thanks Brady, I have now tried the Windows 5.0.0 zip file version and get to this point:

Step 3

Configuring OpenEMR…

Connecting to MySQL Server… OK.
Creating database… ERROR. Check your login credentials. unable to execute SQL: ‘create database openemr character set utf8 collate utf8_general_ci’ due to: Can’t create database ‘openemr’; database exists

Do I need to remove my current xampp installation to remove vestiges of earlier installation attemps?

I will answer my own question by looking at past advice that needed one to open Phpadmin on the Localhost and Drop (delete) the database called Openemr

The class adodb-xmlschema.inc.php included in the .zip files is not compatible with PHP 7.1. If you are able to find and edit the file to replace all of the code in that file with all of the code presented here…ADOdb/adodb-xmlschema.inc.php at master · ADOdb/ADOdb · GitHub, it should work. I deleted the contents of adodb-xmlschema.inc.php, then copied and pasted this code in, saved the file, refreshed the page at step 4, and it continued with a successful install. Good luck!

Related issue on github here for reference:

And here’s the commit that brought in the new version of adodb into the development codebase:
