A simple web interface for GCC

This was my college mini-project actually. What I tried to do was create a simple web interface for GNU compiler collections, using PHP. It did turn out to be successful.

Features:
  • Written in HTML and PHP.
  • Allows execution of C and C++ code.
  • Accepts code, standard input, command-line arguments, and text input.
  • Supports multiple execution sessions.

More features, interface improvements and graphics coming along. Stay tuned.

Requirements:

  • Linux distribution (preferably Debian)
  • Apache webserver (2.2 or greater)
  • PHP 5.4 or greater
  • shell_exec() should be enabled

Installation:

  1. Download the repo as a zip file, extract it locally into a folder named 'webgcc'.
  2. (a)The script files should be placed in /var/www/. This can be achieved by just copying the 'webgcc' script folder into the directory.

    (b)Alternatively, if the script is to be hosted by a particular user account, a VirtualHost should be created pointing to the public_html directory of that user. The instructions on creating a VirtualHost can be found in Apache HTTP server manual at http://httpd.apache.org/docs/2.2/vhosts/examples.html. After the VirtualHost is created, the user account must be added to the www-data group, and the group ownership of the public_html directory must be set to www-data, along with the proper permissions. This is done by issuing the following commands in order in the terminal:
    cd /home/user/ (where 'user' is the username of the user account)
    chown -R user.www-data public_html
    usermod -a -G www-data user
    chmod 775 public_html

    Finally the 'webgcc' script folder must be copied into public_html directory.
  3. The 'webgcc' folder must have writeable permissions, so it's most recommended to set the permissions to 775. This is done by navigating to the working directory from the terminal and issuing the command:
    chmod 775 webgcc
  4. Finally the script files should be set with the proper permissions (755). This is done by typing the following commands in order:
    cd webgcc
    chmod 755 *

Usage:

Usage is really simple, just open the URL of the interface from a browser. Here are some screenshots to help you get up and running.

Changelog:
