Configure
Using configure script is a method to generate makefiles before compilation in Unix systems.
When installing Hercules, configure script should be run after Git Clone and before compiling.

Basic usage
To avoid errors in server-client communication, PACKETVER must be set to date the client you're going to use has been released at (in YYYYMMDD format), eg 20100730 for 2010-07-30aRagexeRE. Instead of editing mmo.h directly, PACKETVER can be set to desired date with configure switch --enable-packetver=YYYYMMDD.
Run following command, replacing YYYYMMDD with your client release date, eg 20100730.
./configure --enable-packetver=YYYYMMDD
Configure script will perform necessary tests and generate makefiles.

Setting executable bit
In order to run configure script it must be executable, ie have the execute permission set. When checking out a working copy from a git repository repository, executable bit should be set automatically. However, if it fails for some reason, running ./configure will bring the following message (or similar):
bash: ./configure: Permission denied
To fix this, set executable permission with:
chmod +x ./configure
Additional switches
To display all available switches use:
./configure --help
Debug mode
It is possible to compile Hercules in debug mode with --enable-debug switch.
