When the input line contains only whitespace, player->argp[0] is null after parse(). This condition was not checked, comtch() returned M_IGNORE, and code handling that printed the null pointer. Some systems (GNU, Windows) deal gracefully with printing null strings, others crash. Trivial to trigger remotely. Before the fix, the value of parse() was assigned, but never used, and that was spotted by the Clang Static Analyzer. |

Welcome to Empire 4, code-named Wolfpack.
Empire is a multi-player, client/server Internet based war game.

it under the terms of the GNU General Public License as published by

See file `CREDITS' for a list of contributors.
Directory `doc' has additional information. File `doc/README'
describes the files there and what they talk about.
To build the server and set up a game, follow the steps below.
(1) Unpacking the source tree
If you downloaded a tarball, unpack it.
If you cloned a git repository, run bootstrap. This requires
recent versions of Autoconf and Automake to be installed.
(2) Building a server
Prerequisites: IEEE Std 1003.1-2001 (POSIX.1-2001), GNU make, a
curses library, Perl, and either nroff or GNU troff (`groff').
See file `INSTALL' for detailed compilation and installation
instructions. Quick guide for the impatient: run configure; make;
make install. The last step is optional; everything runs fine
right from the build tree.
If make fails without doing anything, you're probably not using
GNU make. Some systems have it installed as `gmake'.
Solaris supports POSIX.1-2001, but you need to set up your
environment for that. Try passing
SHELL=/usr/xpg4/bin/sh PATH=/usr/xpg6/bin:/usr/xpg4/bin:$PATH
to make. See standards(5) for details.
(3) Creating a game
* Create a configuration for your game. make install installs one
in $prefix/etc/empire/econfig ($prefix is /usr/local unless you
chose something else with configure). You can use pconfig to
create another one.
* Edit your configuration file. See doc/econfig for more
information.
Unless you put your configuration file in the default location
(where make install installs it), you have to use -e with all
programs to make them use your configuration.
* Run files to set up your data directory.
* Run fairland to create a world. For a sample world, try
`fairland 10 30'. This creates file ./newcap_script, which will
be used below. You can edit it to change country names and
passwords.
Check out fairland's manual page for more information.
* Start the server. For development, you want to run it with -d
in a debugger, see doc/debugging. Do not use -d for a real
game!
* Log in as deity POGO with password peter. This guide assumes
you use the included client `empire', but other clients should
work as well.
For help, try `info'.
To change the deity password, use `change re <password>'.
* Create countries with `exec newcap_script'.
Your game is now up!
Naturally, there's more to running a real game than that, but that's
beyond the scope of this file.
