makefile.djgpp

quake1 dos源代码最新版本

#
# DJGPP makefile for DOSQuake by Norberto Alfredo Bensa <[e-mail]>
# Usage: make -f makefile.djgpp [DEBUG=X] [VERBOSE=X]
#
# Use DEBUG=X for a debug version
# Use VERBOSE=X to see all the tool calls
#
# --------------------------------------------------------------------------
#
# Necessary changes for the code to work with DJGPP:
# 1. Remove the "static" statement for the isDedicated variable in SYS_DOS.C
# 2. Add the following to lines to SYS_DOS.C to fix the memory detection bug
#    #include <crt0.h>
#    int _crt0_startup_flags = _CRT0_FLAG_UNIX_SBRK;
# 3. There are more bugs in DOSQuake, for a list of known Quake bugs visit
#    the Quake Info Pool through http://www.bigfoot.com/~maddes (redirection)
#
# --------------------------------------------------------------------------
#
# Packages needed to build DOSQuake can be downloaded at http://www.delorie.com/djgpp/
# (ftp://ftp.simtelnet.net/pub/simtelnet/gnu/djgpp/)
#
# Go to the ZipPicker page and choose the following for the minimum download:
# - "Build and run programs with DJGPP"
# - state your OS
# - online-documentation: "yes" (not necessary, but helpful)
# - programming language: "C"
# - you don't need RHide or the GNU debugger
# - get the extra documentation formats if you are not used to info
#
# As of 2000-07-27 you will get the following download list (older versions may work too)
