LabelMeAnnotationTool_Archlinux.md

Install the required packages:

$ sudo pacman -S apache perl perl-cgi php php-cgi php-apache

Download the application code, put it to the server directory, and configure:

$ sudo git clone https://github.com/CSAILVision/LabelMeAnnotationTool.git /srv/http/LabelMeAnnotationTool
$ cd /srv/http/LabelMeAnnotationTool
$ sudo make

If using default /etc/httpd/conf/httpd.conf, perform the following changes:

### Switch to `mod_mpm_prefork.so`. ! THIS IS A MUST FOR PHP7 !
# LoadModule mpm_event_module modules/mod_mpm_event.so

</IfModule>
<IfModule mpm_prefork_module>
	LoadModule cgi_module modules/mod_cgi.so
</IfModule>
...
LoadModule rewrite_module modules/mod_rewrite.so

### Add `php7_module`

### We'll use a virtual host, so uncomment this
Include conf/extra/httpd-vhosts.conf

Comment the examples in /etc/httpd/conf/extra/httpd-vhosts.conf and put the following configuration:

### If you'd like to work locally
#<VirtualHost 127.0.0.1:80>
### If you'd like to expose the service to the network
