# winbuild.sh: Cross-compiling freeciv from linux to Windows using Crosser dllstack

# This script is licensed under Gnu General Public License version 2 or later.
# See COPYING available from the same location you got this script.

# Version 1.3.4.2 (13-Aug-15), for freeciv branches S2_6 and later

#
# 1. Adjust hardcoded WINCCPATH + DLLSPATH below to point to dllstack installation directory in your system.
#    Here WINCCPATH is upper level directory, where actual dllstack directories are: "current32" being
#    win32 dllstack, and "current64" being win64 dllstack. In my system "current32" and "current64" are
#    symbolic links to dllstack version in use.
# 2. Take svn checkout of Freeciv code
# 3. Adjust hardcoded TOLUAPATH below to point to tolua program native to build system.
#    If you cannot get it otherwise, you can build it from freeciv sources:
#    3a) Make native freeciv build
#       3a1) Make subdirectory "natbuild" to checkout
#       3a2) cd natbuild
#       3a3) ../autogen && make
#    3b) Copy produced natbuild/dependencies/tolua-5.2/src/bin/tolua to safe place
# 4. Make subdirectory "build" to checkout
# 5. Place this script to "build" directory
# 6. cd build
# 7. ./winbuild.sh
