# Quake2 gamei386.so Makefile for Linux 2.0
#
# Jan '98 by Zoid <zoid@idsoftware.com>
#
# ELF only
#
# Probably requires GNU make
#
# This builds the gamei386.so for Linux based on the q2source_12_11.zip
# release.  
# Put his Makefile in the game subdirectory you get when you unzip
# q2source_12_11.zip.
#
# There are two compiler errors you'll get, the following fixes
# are necessary:
#
# In g_local.h (around line 828), you must change the 
#    typedef struct g_client_s { ... } gclient_t;
# to just:
#    struct g_client_s { ... };
# The typedef is already defined elsewhere (seems to compile fine under
# MSCV++ for Win32 for some reason).
#
# m_player.h has a Ctrl-Z at the end (damn DOS editors).  Remove it or
# gcc complains.
#
# Note that the source in q2source_12_11.zip is for version 3.05.  To
# get it to run with Linux 3.10, change the following in game.h:
#    #define	GAME_API_VERSION	1
# change it to:
#    #define	GAME_API_VERSION	2
