# build Subsurface for Win32
#
# this file assumes that you have installed mxe on your system
# and installed a number of dependencies as well
# it also makes some assumption about the filesystem layout based
# on the way things are setup on my system so I can build Ubuntu PPA,
# OBS and Windows out of the same sources.
# Something like this:
#
# ~/src/win/mxe                    <- current MXE git with Qt5, automake
#      /win/libxml2                <- libxml from git
#      /win/libxslt                <- libxslt from git
#      /win/libzip-0.11.2          <- libzip sources from their latest distribution tar ball
#      /subsurface                 <- current subsurface git
#      /subsurface/libdivecomputer <- appropriate libdc branch
#      /subsurface/marble-source   <- appropriate marble branch
#      /subsurface/libgit2         <- appropriate libgit2 branch
#
# ~/src/win/win32                  <- build directory
#                /libxml2
#                /libxslt
#                /libzip
#                /libgit2
#                /marble
#                /subsurface
#
# then start this script from ~/src/win/win32
#
#  cd ~/src/win/win32
#  bash ../../subsurface/packaging/windows/mxe-based-build.sh installer
#
# this should create the latest daily installer
